1.i :(i) Asymmetric Addition with Different Amounts of Chiral Ligand; With reference to the following Scheme 4, it shows that ethyl in diethyl zinc is added to the aldehyde in the presence of η-amino thiol 40 used as a chiral ligand. Compound 40 (the used amount thereof listed in Table 1) and benzaldehydes (2 mmol) placed in a 10-ml round-bottomed flask were stirred for 10 minutes at predetermined temperatures (shown in Table 1).Subsequently, diethyl zinc in n-hexane (1 M, 3 ml, 3 mmol) was added slowly along the inner wall of the flask. Posterior to several hours (shown in Table 1) of stirring, NH4Cl aqueous solution (1 N, 1 ml) was added to cease reaction, and then 1 N HCl aqueous solution was added for neutralization (pH=7). The organic and water phases were separated and the water phase was extracted with dichloromethane (20 ml.x.3). The organic phase collected was dried with anhydrous sodium sulfate, filtrated, and then condensed. The crude extract was purified by chromatography (eluent:ethyl acetate:n-hexane=1:6) to give the adduct and the results are listed in Table 1.

4.22. Enantioselective addition of diethylzinc to benzaldehyde in presence of ligands 15-19, 29-35, 45 and 46 (General procedure) Enantioselective addition of diethylzinc to benzaldehyde in presence of ligands 15-19, 29-35, 45 and 46 (General procedure) To a solution of the corresponding ligand in 6 ml of hexane or toluene, Et2Zn (5.6 ml, 5.60 mmol of 1 M solution in hexane) was added dropwise at 0 °C. The mixture was stirred for 30 min at 0 °C and then benzaldehyde (0.288 ml, 2.83 mmol) was added at 0 °C. The reaction was stirred at room temperature and monitored by TLC (petroleum ether/Et2O = 5:1) until the full consumption of benzaldehyde.

The mixture was quenched at 0 °C (aq. NH4Cl), extracted with Et2O (3 * 20 ml) and organic phase was dried over anhydrous Na2SO4.

The solvent was evaporated in vacuo and the crude product was chromatographed (15 g silica gel, petroleum ether/Et2O = 6:1) to obtain pure 1-phenyl-1-propanol as a mixture of both enantiomers.

For the ee determination of 1-phenyl-1-propanol, see Section 4.1 .

4.3. Asymmetric addition of diethylzinc to aldehydes; generalprocedure General procedure: Chiral catalysts of type 4 (0.1 mmol) in dry toluene (5 mL) were placed in a round-bottomed flask. The mixture was cooled to 0 °C and a solution of diethylzinc (1.0 M sln. in hexane, 3.0 mmol) was added under argon. After stirring for 30 min, an aldehyde (1.0 mmol) was added at 0°C, and the mixture was stirred at room temperature overnight. Next, a 5percent HCl aqueous solution was added, the layers were separated, and the aqueous phase was extracted with diethyl ether (4×10 mL). The combined organic layers were washed with brine (10 mL) and dried over anhydrous MgSO4. The solvents were evaporated off to afford the crude alcohols 5a–e, which were purified via column chromatography on silica gel (hexane with ethyl acetate in gradient). The yields, specific rotations, enantiomeric excess values, and the absolute configurations of products 5a–e are collected in Table 3. The spectroscopic data were in full agreement with those reported in the literature.

General procedure for enantioselective additions of diethylzinc to aldehydes General procedure: To a well-dried Schlenk tube charged with Bu4NBr (32.2 mg, 0.10 mmol, 10 mol percent), a solution of chiral ligand L1 (1 mL, 0.5 mol percent, 0.5 x 10-2 M in toluene) and dry toluene (1.0 mL) was added, then diethylzinc (1.0 M in hexane, 2.0 mL, 2.0 mmol, 2.0 equiv) was slowly added at 0 °C via a syringe under nitrogen atmosphere. After being stirred for 30 min, aldehyde (1a, 106 mg, 101.4 μL, 1.0 mmol) was added dropwise to the mixture at 0 °C . The mixture was stirred for 6 h at room temperature and quenched by addition of aqueous HCl (1.0 M, 5 mL). Extraction with EtOAc (10 mL x 3) gave combined organic layers that were washed with brine (10 mL), dried over MgSO4, and concentrated in vacuo to give a residue that was subjected to silica gel column chromatography (EtOAc/hexane = 1/10), which afforded the corresponding enantio-enriched secondary alcohol (2a) as a colorless oil. The ee value of the secondary alcohol was determined by Chiral GC. The absolute configuration of the alcohol was assigned as (R) by comparison of the optical rotation with reported data.

To a stirred solution of the catalyst (0.20 equiv) in toluene (2 mL) at 0 0C was added diethylzinc (1.0 M in hexane, 1.08 mL). After stirring the reaction for 30 min at 0 0C. benzaldehyde (0.05 mL. 0.49 mmol) was added and the reaction was stirred at this temperature for 24 h. The reaction was quenched with an aqueous saturated solution of ammonium chloride (2 mL). and the mixture was extracted with diethyl ether (3 x 5 mL).

Diethylzinc (1.0 M in hexane, 0.39 mL) was added dropwise to a solution of 75d (1 1 mg, 0.02 mmol) in toluene (2 mL) at room temperature. After 15 h, phenylacetylene (0.06 mL, 0.41 mmol) was added at room temperature and the reaction was stirred for 1 h. Benzaldehyde (0.02 mL, 0.20 mmol) was then added and the reaction was stirred for 24 h at room temperature. The reaction was quenched with water and extracted with diethyl ether (2 x 5 mL).

Retention times: R (minor) 7.50 min, S (major) 10.48 min.40aToluene proved to be the better solvent for the reaction since a slight decrease in ee to 72percent was observed when catalyst 75a was used in cyclohexane. Conditions where an additive, such as titanium(IV) isopropoxide. were also attempted with catalyst 75a. but both a low yield and low ee's were obtained (4percent and 6percent. respectively). Only results from the standard reaction conditions are shown in Table 14.Both diastereomers of the secondary alcohols were examined as catalysts in the reaction, shown in entries 2-9. Interestingly, only diastereomers with the absolute configuration of 74a-d had a significant effect on the enantioselectivity. In addition, in every case where a significant enatioselectivity was observed, the primary product was the R enantiomer.Compound 74d (entry 9) gave the highest enantiomeric excess for this class of ligands: however, the 1-naphthyl substituted ligand 74c provided a similar ee of 76percent with an 83percent yield. In the case of 74d. the electron-withdrawing effect of the fluorines on the aromatic ring created a decrease in the yield as compared to 74a-c.When comparing the selectivity provided by catalysts 74c and 74d (76percent ee and 79percent ee. respectively) with 74a and 74b (both 64percent ee) it appears that selectivity can be increased by either adding more electron withdrawing substituents or increasing the steric hindrance. These findings were also observed in the series of tertiary alcohols 75a-d. The decafluorobenzophenone tertiary alcohol 75d gave a 95percent ee, while the benzophenone tertiary alcohol 75a only gave 79percent ee (entries 10 and 13). The greater steric bulk of 75b gave an ee of 83percent. while the smaller tertiary alcohol 75c only afforded 66percent ee (entries 11 and 12).

Lower yield due to difficulties m purificationIn general, the tertiary alcohols, entries 10, 11, and 13. enhanced the selectivity of the reaction more than the secondary alcohols. The decafluoro tertiary alcohol 75d proved to provide one of the best enantioselectivities (95percent ee) overall, but gave the lowest yield.Surprisingly, the increased steric bulk provided by the tert-butyl groups on compound 75c did not improve the selectivity over that afforded by 75d and even decreased the selectivity when compared to the smaller compound 75a. Gau and Wu discovered with their η-amino alcohol systems that aromatic substituents increased the ee, while alkyl substituents decreased the ee (Gau, H. M.; Wu, K. H. Or ganomet allies 2003, 22, 5193-5200). Their finding is consistent with the results in Table 14 when comparing the tertiary and secondary alcohols. For example, the additional phenyl group on 75a (Table 3, entry 10) causes an increase in the selectivity by about 10 percent ee over that of entry 3. This shows that increase in steric bulk of the catalyst does help to increase enantioselectivity. However, catalyst 75b did not seem to show much of an increase in yield or selectivity from 75a suggesting that the 2-naphthyl substituents do not increase the sterics much from the phenyl substituents.Upon determining 75d as the catalyst with the highest selectivity at 20 mol percent, the asymmetric reaction parameters were optimized by varying the conditions of the reaction by lowering the catalyst loading (Table 4). When going from 20 mol percent to 10 mol percent of catalyst 75d, only a slight change in percent yield and percent ee were observed. Much to our delight, the reaction went further to completion when 5 mol percent of catalyst 75d was employed in the reaction than when 10 percent was used. However, when the amount of catalyst was further reduced to 2 mol percent of 75d, a decrease in the yield and selectivity was observed (Table 4, entry 4).Table 4: Variation of the catalyst loading using 75d as the ligand for the diethylzinc addition to benzaldehydeaLo\\ver yield due to difficulties in purification.Using the optimized asymmetric reaction conditions. 75d was used to catalyze the addition of diethylzinc to other aldehyde substrates as shown in Table 5. The -Cl and - OCHs substituents on the aromatic ring did not seem to have a large effect on the enantiocontrol of the reaction (entries 2 and 3) and afforded results similar to benzaldehyde; however, the yield of the reaction was lower with chlorobenzaldehyde as the substrate. When cinnamaldehyde and hydrocinnamaldehyde were employed in the

reaction, a decrease in the enantioselectivity was observed.Table 5: Diethylzinc additions to aldehydes catalyzed by 75d (5 mol percent)Overall, the novel nicotine-based decafluorodiphenyl catalyst demonstrates respectable yields and high enantioselectivities when employed in the catalytic asymmetric addition of diethylzinc to aromatic aldehydes. Finally, to investigate the effect of the chlorine substituent on the nicotine-based catalysts during the asymmetric reaction, compounds 9028 and 91 were synthesized and compared to 75a (Schemes 3 and 4). This comparison would provide insight as to whether or not the C-4 substituted nicotine-based compounds could be improved to enhance selectivity in the asymmetric reaction by adding or removing chlorine substituents from the pyridine ring.Scheme 3: Synthesis of 9090Scheme 4: Synthesis of 91Addition of a chlorine substituent to the C-5 position of nicotine, as shown with compound 90, increased the selectivity to 95percent ee at 20 mol percent, but at 5 mol percent a slight decrease in selectivity was observed (Table 6, entries 3 and 4). In contrast, catalyst 91 with no chlorine substituents decreased the selectivity as compared to ligand 75a as seen in Table 6, entries 5 and 6. The selectivity and yield were worse when the amount of catalyst 91 was lowered to 5 mol percent. Therefore, it may be desirable to have at least one chlorine substituent on the nicotine portion of the molecule, in addition to the alcohol functionality off of the C-4 position, in order to maintain adequate selectivity in the asymmetric reaction. Table 6: Comparing catalysts 75a, 75d, 90 and 91 in the asymmetric reaction of diethylzinc and benzaldehydea aReacrioηs were run at 0 ~C for 24 h in toluene.In conclusion, the more sterically hindered C-4 tertiary alcohols of (ηS)-6-chloronicotine provided better enantio selectivity than the C-4 secondary alcohols. Additionally, electron withdrawing fluorines on the aromatic ring improved the ee as compared to electron donating groups, as seen when comparing catalyst 75d with 75a and 75c. The effect of the chlorines on the pyridine ring of nicotine also proved to be beneficial when applied to the asymmetric reaction. Two chlorine substituents on nicotine derivative 90 proved to be superior to only one chlorine substituent on molecule 75a. When no chlorines were on C-4 substituted 91, the yield and the selectivity decreased noticeably.Overall, compound 75d provided the most promising results, yielding an ee of 95percent when benzaldehyde was the substrate and only 5 mol percent of the catalyst was used. The catalyst also provided acceptable results when other substrates were employed in the asymmetric reaction.However, compound 75d with zinc(II) triflate yielded very little product was obtained (data not shown). The diethylzinc conditions were applied where the product 93 was obtained with a 93percent yield with a 13percent ee, but some ethylphenyl alcohol 17 was also observed. In addition, when applied to the Henry reaction, the yields were very low (data not shown).

9 :The bisimidate ligands were further tested in 1,2-additions of diethylzinc to benzaldehyde. Amino-alcohols are the ligands of choice in this type of reaction. It is known that bisoxazolines without a hydroxyl substituent give low enantioselectivities. (Ref. 7)A typical procedure is as follows: Bisimidate (IIb) (6.0 mg, 0.012 mmol) was dissolved in toluene (2 mL). Et2Zn (0.75 mL, 1 M in hexane) was added and the resulting yellow solution was stirred for 20 min at room temperature under argon atmosphere.

Next, benzaldehyde X (50 μL, 0.49 mmol) was added and the reaction mixture was stirred for another 24 h. The reaction was quenched with 1 mL saturated NH4Cl solution. The reaction mixture was poured in H2O (25 mL) and extracted with EtOAc (3.x.25 mL). The combined organic phases were dried over Na2SO4 and evaporated in vacuo. Purification by flash chromatography over silica gel (pentane/EtOAc, 90/10) resulted in XI, 55.7 mg (83percent, 75percent ee).

4.6. Addition of diethylzinc on aryldehydes General procedure: 4.6.1. General procedure. In an oven-dried 5 mL flask under argon atmosphere, the ligand (0.1 equiv, 0.1 mmol) was dissolved in 2.5 mL of anhydrous toluene and diethylzinc (1.5 M in toluene, 2 mmol) was added dropwise. The solution was cooled to 0 °C for 15 min and the aldehyde (1 equiv, 1 mmol) was added as a single portion. The mixture was then warmed to room temperature and stirred for 48 h before 1 N HCl was added. The resulting alcohol was extracted with three portions of EtOAc. The organic layers were then combined, washed with brine, dried with Na2SO4, and concentrated in vacuo, giving an oil from which conversion and enantiomeric excess were determined by GC. In one case involving benzaldehyde and ligand 23a (Table 3, entry 1), the crude product was purified by flash chromatography (5:95 EtOAc/hexanes), giving 81percent isolated yield of 32. Commercially available (S)-1-phenyl-1-propanol was used for enantiomer identification on the GC chromatograms. Products 33 and 35, as control experiments, were also prepared from Grignard addition reactions and analyzed by GC.

Diethylzinc (1 M in heptane; 1 m L) was introduced into a Schlenk under a nitrogen atmosphere. Toluene (0.5 mL), ligand 7a (0.04 mmol in 0.5 mL toluene) and benzaldehyde (0.5 mmol) were subsequently added. The reaction mixture was stirred at room temperature over a period of 24 hours, cooled to O0C and subsequently quenched with an aqueous HCI solution (2M, 5 mL). The reaction mixture was washed with diethyl ether (3 x 5 mL), followed by washing with a saturated aqueous sodium chloride solution. The organic layer was dried using anhydrous magnesium sulfate and filtered. Upon removal of the solvent, the product was isolated by means of thin layer chromatography (hexane/ethyl acetate, 5:1). The fraction having an Rf of 0.37 was collected. The fraction was subsequently extracted with chloroform to yield the product as a yellow oil.

Each of these ligands was added, and benzaldehyde and diethylzinc were reacted to synthesize an optically active secondary alcohol. 3.0 ml (3.0 mmol) of diethylzinc (1.0 M toluene solution) was added to a Schlenk reaction tube containing 0.10 mmol of the phosphoramide compound (L1) or the ligands (L3) to (L12) under a nitrogen atmosphere, and stirred at 0°C for 30 minutes. Then, 1.0 mmol of benzaldehyde was added to the reaction solution and stirred at 0°C for 24 hours. The completion of the reaction was confirmed by a TLC. After confirmation, 10 ml of a saturated aqueous ammonium chloride solution was added and warmed to room temperature. Extraction from the mixture was performed twice using 15 ml of diethyl ether. The extracted organic layer was washed with 10 ml of a saturated sodium chloride aqueous solution, and dried with magnesium sulfate. Then, the filtration was performed using "Celite" (trade name), and the solvent was distilled off under reduced pressure. The obtained concentrated liquid was purified by passing through silica gel column chromatography(pentane/diethyl ether = (10/1) to (2/1)), and thus an optically active secondary alcohol was obtained. The structure of the synthesized optically active secondary alcohol, the reaction time, yield, and enantiomeric excess are indicated together with the structure of each of the above ligands.

Conditions where an additive, such as titanium(IV) isopropoxide. were also attempted with catalyst 75a. but both a low yield and low ee's were obtained (4percent and 6percent. respectively). Only results from the standard reaction conditions are shown in Table 14.Both diastereomers of the secondary alcohols were examined as catalysts in the reaction, shown in entries 2-9. Interestingly, only diastereomers with the absolute configuration of 74a-d had a significant effect on the enantioselectivity. In addition, in every case where a significant enatioselectivity was observed, the primary product was the R enantiomer.Compound 74d (entry 9) gave the highest enantiomeric excess for this class of ligands: however, the 1-naphthyl substituted ligand 74c provided a similar ee of 76percent with an 83percent yield. In the case of 74d. the electron-withdrawing effect of the fluorines on the aromatic ring created a decrease in the yield as compared to 74a-c.When comparing the selectivity provided by catalysts 74c and 74d (76percent ee and 79percent ee. respectively) with 74a and 74b (both 64percent ee) it appears that selectivity can be increased by either

adding more electron withdrawing substituents or increasing the steric hindrance. These findings were also observed in the series of tertiary alcohols 75a-d. The decafluorobenzophenone tertiary alcohol 75d gave a 95percent ee, while the benzophenone tertiary alcohol 75a only gave 79percent ee (entries 10 and 13). The greater steric bulk of 75b gave an ee of 83percent. while the smaller tertiary alcohol 75c only afforded 66percent ee (entries 11 and 12).

Lower yield due to difficulties m purificationIn general, the tertiary alcohols, entries 10, 11, and 13. enhanced the selectivity of the reaction more than the secondary alcohols. The decafluoro tertiary alcohol 75d proved to provide one of the best enantioselectivities (95percent ee) overall, but gave the lowest yield.Surprisingly, the increased steric bulk provided by the tert-butyl groups on compound 75c did not improve the selectivity over that afforded by 75d and even decreased the selectivity when compared to the smaller compound 75a. Gau and Wu discovered with their η-amino alcohol systems that aromatic substituents increased the ee, while alkyl substituents decreased the ee (Gau, H. M.; Wu, K. H. Or ganomet allies 2003, 22, 5193-5200). Their finding is consistent with the results in Table 14 when comparing the tertiary and secondary alcohols. For example, the additional phenyl group on 75a (Table 3, entry 10) causes an increase in the selectivity by about 10 percent ee over that of entry 3. This shows that increase in steric bulk of the catalyst does help to increase enantioselectivity. However, catalyst 75b did not seem to show much of an increase in yield or selectivity from 75a suggesting that the 2-naphthyl substituents do not increase the sterics much from the phenyl substituents.Upon determining 75d as the catalyst with the highest selectivity at 20 mol percent, the asymmetric reaction parameters were optimized by varying the conditions of the reaction by lowering the catalyst loading (Table 4). When going from 20 mol percent to 10 mol percent of catalyst 75d, only a slight change in percent yield and percent ee were observed. Much to our delight, the reaction went further to completion when 5 mol percent of catalyst 75d was employed in the reaction than when 10 percent was used. However, when the amount of catalyst was further reduced to 2 mol percent of 75d, a decrease in the yield and selectivity was observed (Table 4, entry 4).Table 4: Variation of the catalyst loading using 75d as the ligand for the diethylzinc addition to benzaldehydeaLo\\ver yield due to difficulties in purification.Using the optimized asymmetric reaction conditions. 75d was used to catalyze the addition of diethylzinc to other aldehyde substrates as shown in Table 5. The -Cl and - OCHs substituents on the aromatic ring did not seem to have a large effect on the enantiocontrol of the reaction (entries 2 and 3) and afforded results similar to benzaldehyde; however, the yield of the reaction was lower with chlorobenzaldehyde as the substrate. When cinnamaldehyde and hydrocinnamaldehyde were employed in the reaction, a decrease in the enantioselectivity was observed.Table 5: Diethylzinc additions to aldehydes catalyzed by 75d (5 mol percent)Overall, the novel nicotine-based decafluorodiphenyl catalyst demonstrates respectable yields and high enantioselectivities when employed in the catalytic asymmetric addition of diethylzinc to aromatic aldehydes. Finally, to investigate the effect of the chlorine substituent on the nicotine-based catalysts during the asymmetric reaction, compounds 9028 and 91 were synthesized and compared to 75a (Schemes 3 and 4). This comparison would provide insight as to whether or not the C-4 substituted nicotine-based compounds could be improved to enhance selectivity in the asymmetric reaction by adding or removing chlorine substituents from the pyridine ring.Scheme 3: Synthesis of 9090Scheme 4: Synthesis of 91Addition of a chlorine substituent to the C-5 position of nicotine, as shown with compound 90, increased the selectivity to 95percent ee at 20 mol percent, but at 5 mol percent a slight decrease in selectivity was observed (Table 6, entries 3 and 4). In contrast, catalyst 91 with no chlorine substituents decreased the selectivity as compared to ligand 75a as seen in Table 6, entries 5 and 6. The selectivity and yield were worse when the amount of catalyst 91 was lowered to 5 mol percent. Therefore, it may be desirable to have at least one chlorine substituent on the nicotine portion of the molecule, in addition to the alcohol functionality off of the C-4 position, in order to maintain adequate selectivity in the asymmetric reaction. Table 6: Comparing catalysts 75a, 75d, 90 and 91 in the asymmetric reaction of diethylzinc and benzaldehydea aReacrioηs were run at 0 ~C for 24 h in toluene.In conclusion, the more sterically hindered C-4 tertiary alcohols of (ηS)-6-chloronicotine provided better enantio selectivity than the C-4 secondary alcohols. Additionally, electron withdrawing fluorines on the aromatic ring improved the ee as compared to electron donating groups, as seen when comparing catalyst 75d with 75a and 75c. The effect of the chlorines on the pyridine ring of nicotine also proved to be beneficial when applied to the asymmetric reaction. Two chlorine substituents on nicotine derivative 90 proved to be superior to only one chlorine substituent on molecule 75a. When no chlorines were on C-4 substituted 91, the yield and the selectivity decreased noticeably.Overall, compound 75d provided the most promising results, yielding an ee of 95percent when benzaldehyde was the substrate and only 5 mol percent of the catalyst was used. The catalyst also provided acceptable results when other substrates were employed in the asymmetric reaction.However, compound 75d with zinc(II) triflate yielded very little product was obtained (data not shown). The diethylzinc conditions were applied where the product 93 was obtained with a 93percent yield with a 13percent ee, but some ethylphenyl alcohol 17 was also observed. In addition, when applied to the Henry reaction, the yields were very low (data not shown).

1.i :(i) Asymmetric Addition with Different Amounts of Chiral Ligand; With reference to the following Scheme 4, it shows that ethyl in diethyl zinc is added to the aldehyde in the presence of η-amino thiol 40 used as a chiral ligand. Compound 40 (the used amount thereof listed in Table 1) and benzaldehydes (2 mmol) placed in a 10-ml round-bottomed flask were stirred for 10 minutes at predetermined temperatures (shown in Table 1).Subsequently, diethyl zinc in n-hexane (1 M, 3 ml, 3 mmol) was added slowly along the inner wall of the flask. Posterior to several hours (shown in Table 1) of stirring, NH4Cl aqueous solution (1 N, 1 ml) was added to cease reaction, and then 1 N HCl aqueous solution was added for neutralization (pH=7). The organic and water phases were separated and the water phase was extracted with dichloromethane (20 ml.x.3).

4.12. General procedure for the reaction of aldehydes with diethylzinc in the presence of chiral catalyst (-)-5-(-)-15 General procedure: To the respective catalyst (0.1 mmol) 5-15, 1 M Et2Zn in n-hexane solution (3 mL, 3 mmol) was added under an argon atmosphere at room temperature. The reaction was stirred for 25 min at room temperature, and benzaldehyde (1 mmol) was then added to the solution, with subsequent stirring at room temperature for a further 20 h. The reaction was quenched with a saturated NH4Cl solution (15 mL) and the mixture was extracted with EtOAc (2 .x. 20 mL). The combined organic phase was washed with H2O (10 mL), dried (Na2SO4) and evaporated under vacuum. The crude secondary alcohols obtained were purified by flash column chromatography (n-hexane/EtOAc = 4:1). The enantiomeric excess and absolute configuration of the resulting material were determined by chiral GC, using a chiral stationary phase (Chirasil-Dex CB column) at 90 °C for 1-phenyl-1-propanol 17 and 18 [tR1 = 7.0 min for the (S)-isomer, tR2 = 8.1 min for the (R)-isomer]. [33] and [34] The direction of the specific rotation of each product was also checked.

Typical procedure 2 for the catalytic alkylation of benzaldehyde with titanium complexes of amino alcohols General procedure: In a glove box, hexane (1 mL) and a 1 M solution of diethyl zinc in hexane (3.7 mL, 3.7 mmol) were added to a 2 neck 25 mL round bottomed flask. The reaction vessel was taken out of the glove box, and a solution of the ligand (0.0564 mmol, 2 mol percent) dissolved in hexane was added. After stirring for 5 min, the reaction was cooled to -30 °C in a dry ice/ acetone bath. In the glove box, a solution of titanium tetrakis-isopropoxide (16 mg, 0.0564 mmol, 2 mol percent) in hexane (ca.

5 mL) was prepared. The titanium tetrakis-isopropoxide solution was added via syringe, and the reaction was stirred for 10 min.

Next, benzaldehyde (0.29 mL, 2.82 mmol) was added via syringe, and the solution allowed to return to room temperature overnight. Work-up and analysis were as described in typical procedure 1.

Typical procedure 1 for the catalytic alkylation of benzaldehyde with amino alcohols General procedure: In a glove box, hexane (1 mL) and a 1 M solution of diethyl zinc in hexane (3.7 mL, 3.7 mmol) were added to a 2 neck 25 mL round bottomed flask. The reaction vessel was then taken out of the glove box, placed on a nitrogen manifold, and a solution of the ligand (0.0564 mmol, 2 mol percent) dissolved in hexane was added. After stirring for 5 min, the reaction was cooled to -30 °C in a dry ice/acetone bath. Benzaldehyde (0.29 mL, 2.82 mmol) was added via syringe, and the solution allowed to return to room temperature overnight. The reaction was slowly quenched by the addition of hydrochloric acid (2 M, 10 mL). The solution was then separated, extracted with ethyl acetate, washed with a saturated sodium chloride solution, and dried (MgSO4). The solution was then rotary evaporated to give a cloudy liquid, which was chromatographed on silica gel eluting with petroleum ether and ethyl acetate (95:5, 100 mL). Rotary evaporation yielded light-yellow oil, which was used to determine the isolated yield and analyzed by 1H NMR spectroscopy. The product was diluted in ethanol (5 mg/mL) and injected into a chiral GC column (Chiraldex η-DA, 30 m .x. 0.25 μm, 80 °C). Benzaldehyde had a retention time of 7 min; benzyl alcohol had a retention time of 36 min; the two enantiomers of 1-phenylpropanol had retention times of 62 and 63 min for the (S)- and (R)enantiomers, respectively.

General procedure: Diol 4b (67mg, 0.15 mmol) was mixed with titanium isopropoxide (45μl, 0.15 mmol) in toluene (1.5 ml) solution. The mixture was stirred for 20h at room temperature and then concentrated to dryness. The residue was re-evaporated twice with toluene to remove traces of 2-propanol. The prepared solid was dissolved in toluene (2 ml), titanium isopropoxide (0.4 ml, 1.4 mmol) was added, and the solution was cooled to -40ºC. Then benzaldehyde (102 μl, 1 mmol) was added followed by a dropwise addition of diethylzink (1.4 ml, 1.4 mmol, 1M solution in toluene). The yellowish solution was stirred for 24h at -40ºC and then it was diluted with 10 ml of diethyl ether. GC analyses showed a complete conversion. The precipitate was washed with diethyl ether and the combined filtrates were evaporated (rotavapor 200 mbar) to remove the ether. The obtained toluene solution was purified by flash chromatography first with pentane to remove toluene and then with dichloromethane. The fractions containing the product were collected and the solvent was removed. The prepared liquid (110 mg) contained ~70 wtpercent of the 1-phenylpropanol-1 and the rest was DCM. Yield 57percent (low yield because of the losses during isolation caused by low boiling point of the product). Chiral GC analyses showed 20percent ee of the R-enantiomer.

After being stirred for 30 min, aldehyde (1a, 106 mg, 101.4 μL, 1.0 mmol) was added dropwise to the mixture at 0 °C . The mixture was stirred for 6 h at room temperature and quenched by addition of aqueous HCl (1.0 M, 5 mL). Extraction with EtOAc (10 mL x 3) gave combined organic layers that were washed with brine (10 mL), dried over MgSO4, and concentrated in vacuo to give a residue that was subjected to silica gel column chromatography (EtOAc/hexane = 1/10), which afforded the corresponding enantio-enriched secondary alcohol (2a) as a colorless oil. The ee value of the secondary alcohol was determined by Chiral GC. The absolute configuration of the alcohol was assigned as (R) by comparison of the optical rotation with reported data.

After the addition of diethylzinc (1.1 M in toluene) at 0 C,the reaction mixture was stirred at r.t. for a further 36 h, and wasthen quenched with 1 M HCl (4 mL).

The resulting mixture was filteredand the filtrate was extracted with CH2Cl2 (3×10 mL). Thecombined organic layers were dried with anhydrous MgSO4 andconcentrated under reduced pressure. Purification of the residueby flash chromatography (PE/ AcOEt 15:1) afforded the desired alcohol.The enantiomeric excess and the absolute configuration of theresulting alcohols were determined by HPLC and optical rotation.The catalyst was collected by filtration, washed with dry CH2Cl2,vacuum dried and used for a new run. For regeneration, the polymerwas stirred with 1 M HCl-THF (1:2 mL) for 1 h, and then washedsuccessively with CH2Cl2 (3×15 mL), THF (2×15 mL) and MeOH(2×15 mL).

4.11. Typical procedure for the addition of diethylzinc to aldehyde General procedure: To a solution of 4 (0.05 mmol) in freshly distilled diethyl ether(1 mL) diethylzinc (1 mL of 1 M hexane solution, 1 mmol) was added at ambient temperature under argon. The mixture was stirredfor 1 h and then cooled to 15 C. A solution of aldehyde (0.5 mmol) in diethyl ether (1 mL) was added via syringe and the mixture was stirred for 48 h. The reaction was then quenched bythe addition of saturated NH4Cl solution (4 mL), and diphenylmethane (0.25 mmol) was added as an internal standard. The mixture was extracted with EtOAc (3 10 mL) and the combined organic extracts were washed with water (10 mL) and brine (10 mL). The organic layer was dried over anhydrous Na2SO4 and concentrated in vacuo. Conversion and yield were determined from the crude mixture by 1H NMR analysis. The crude product was purified by preparative thin layer chromatography on silica gel (hexane/EtOAc,90:10) and the enantiomeric excess of the addition product was determined by GC on a Chiral b-DEX 120 capillary column.11b With 2-[(1S)-1-hydroxyethyl]-3-{(3S)-3-[(1R)-1-hydroxyethyl]-2,2-dimethylaziridin-1-yl}quinazolin-4(3H)-one in hexane, toluene, Time= 48h, T= -30 °C , Inert atmosphere, Reagent/catalyst, Temperature, Time, enantioselective reaction Celik, Saffet; Cakici, Murat; Kilic, Hamdullah; Sahin, Ertan; Tetrahedron Asymmetry; vol. 26; nb. 2-3; (2015); p. 152 - 157 View in Reaxys Stage 1: With (R,R)-(+)-1,2-bis(2-phenylphenyl)ethane-1,2-diol in hexane, dichloromethane, Time= 0.333333h, T= 20 °C , Inert atmosphere Stage 2: in hexane, dichloromethane, Time= 24h, T= 0 °C , Inert atmosphere, Reagent/catalyst, Solvent, Overall yield = 32 percent; enantioselective reaction Gök, Yaar; Külolu, Soner; Gök, Halil Zeki; Kekec, Levent; Applied Organometallic Chemistry; vol. 28; nb. 11; (2014); p.

General procedure for transferhydrogenation General procedure: In a Schlenk tube under an argon atmosphere, the corresponding metal complex (0.5 or 5 mol percent) is dissolved in 0.1 mL of iso-propanol. A solution of KOH in iso-propanol (40mL, 0.1 M) is then added via syringe. An immediate color change occurs throughout the addition, and a solution of acetophenone (0.2 mmol) in iso-propanol (1.9 mL) is then added.

The mixture is stirred at room temperature overnight. The reaction is quenched by addition of an aqueous solution of HCl (10percent), and the mixture is extracted with CH2Cl2 (3x). The combined organic phases are dried over Na2SO4, filtrated over Celite and the solvent is removed under reduced pressure. The crude mixture is purified by chromatography (silicagel, n-hexane/ ethyl acetate, 4/1, v/v) to obtain the desired secondary alcohol.

Bioreduction of 1a-o by using Lactobacillus reuteri restingcells General procedure: L. reuteri strains were grown in MRS medium. This pre-culture was inoculated in 500 mL of MRS and incubated for 24 h (37° C). Cells were harvested by centrifugation (2800 × g, 10 min)and washed twice with phosphate buffered saline pH 7.4 (PBS,Sigma–Aldrich). Then the cells were suspended in the same bufferand adjusted for cell density. To this cell suspension, 1percent glucose and the desired concentration of arylketone were added (total volume50 mL). To ensure the anaerobic conditions, flasks were degassed with a N2flux for 3 min. The reaction mixture was incubated at 37° C, 200 rpm. Sugars and organic acids were analyzed by HPLCbefore the extraction of the bioconversion products. The reactions progress was monitored by collecting suspension aliquots in a timecourse: after extraction with diethyl ether, the organic phase wasanalyzed by NMR or HPLC. After the appropriate conversion time(see Table 3), the suspension was centrifuged (2800 × g, 10 min,4C), and the aqueous phase was extracted with diethyl ether(3 × 15 mL). The organic phase was dried over Na2SO4, filtered, andevaporated under reduced pressure. The product was isolated bysilica gel column chromatography using hexane and ethyl acetate(90:10 or 80:20) as eluents to yield the desired alcohols (2a-o,Table 2). Absolute configurations of alcohols 2a-o obtained from the bioprocess were determined by comparison of their optical spe-cific rotation signs and/or retention times with known data (See Supporting informations).

The mixture was then stirred at room temperature and the progress of the reaction was monitored by TLC until the specified conversion was achieved. After evaporation of the solvents, 4 mL of CH2Cl2 and 1.5 mL of 10percent aqueous HCl solution were added to the residue. The layers were separated and the water layer was extracted twice with 2 mL of CH2Cl2. The combined organic layers were dried over Na2SO4 and the solvent was evaporated in vacuo. The oily residue was purified by column chromatography on silica gel using chloroform (dried over CaCl2) as eluent to afford the appropriate ketone. The enantiomeric excess was determined by GC analysis using a Supelco cyclodextrinb-DEX 120 capillary column (20 m 0.25 mm I.D. and 0.25 lm film thickness).

The NMR tube was shaken gently and a NMR cap with holes was then fitted. The catalytic mixture was stirred at 28°C for 1h, after which acetophenone (1.1mmol) was added using a syringe. The NMR tube was again shaken gently using a cap without holes and then left to stir at 28°C for the amount of time recorded. The reduction was monitored in two ways: (1) an NMR tube was placed in the NMR spectrometer, and the reaction monitored using a pre-set programme which records chromatograms at regular intervals at 28°C; and (2) at intervals the NMR sample was removed from the oil bath set at 28°C and analysed using the NMR spectrometer. Data analysis was performed using the MestreC software. The conversion of acetophenone to 1-phenylethanol was calculated by comparing the integration of the proton CHOH in the product alcohol (4.9ppm) with the integration of the 3 protons CH3 in acetophenone (2.5ppm).

Representative procedure for transfer hydrogenation reaction ofacetophenone General procedure: To a solution of acetophenone (58 μL, 0.5 mmol) in 2-propanol (0.5 mL) was added a stock solution of manganese pentacarbonyl bromide (0.5 mL, 0.005 mol·L−1; 2.7 mg, 0.010 mmol, in 2 mL 2-propanol)followed, in this order, by a stock solution of ethylenediamine (0.5 mL,0.005 mol·L−1; 1.0 μL, 0.0125 mmol, in 2.5 mL 2-propanol) and tBuOK (0.5 mL, 0.010 mol·L−1; 2.4 mg, 0.020 mmol, in 2 mL 2-propanol). The reaction mixture was stirred for 3 h at 80 °C in an oil bath. The solution was then filtered through a small pad of silica (2 cm in a Pasteur pip-ette). The silica was washed with ethyl acetate. The filtrate was evaporated and the conversion was determined by 1H NMR. The crude residue was then puried by column chromatography (SiO 2 , mixture of petroleum ether/ethyl acetate or dietyl ether as eluent. Enantiomeric excesses were determined by GC analyses performedon GC-2014 (Shimadzu) 2010 apparatus equipped with Supelco beta-DEX 120 column (30 m × 0.25 mm). The determination of the absoluteconguration was done by comparison with (S)-alcohol obtained bykinetic resolution of racemic alcohols with Novozym 435 (CandidaAntarctica Lipase B) and by comparison of the retention times with the literature [32–34].

Typical procedure for the OKR of racemic secondary alcohols General procedure: Racemic secondary alcohols (0.25 mmol), catalyst (1.5 molpercent of substrate), and KBr (0.02 mmol, 0.0024 g) were added to H2O(1.5 mL). The mixture was stirred for 10 min at room temperature, and then PhI(OAc)2 (0.175 mmol, 0.056 g) was added in four equal parts. The reaction progress was monitored by gas chromatography (GC). After achieving the desired oxidation level, the reaction mixture was heated to 40 ηC. The catalyst was precipitated out of the reaction system, washed with diethyl ether(3× 5 mL), dried in a vacuum, and finally recharged with fresh substrate, additive, and oxidant for the next catalytic cycle. The supernatants separated from the reaction system were extractedwith ether three times. The collected organic phase was driedover sodium sulfate and concentrated in a vacuum. The resultantmixture was purified by column chromatography on silica gel athe stationary phase (petroleum ether/ethyl acetate, 90/10). Enantioselectivitywas determined by a Agilent Technologies 6890NGC system equipped with a 19091G-B213 chiral capillary column(30 m×0.32 mm×0.25 m) with an FID.

The reaction vessel was pressurized with H2 to 30 bar and stirred for the desired time at room temperature.

Then pressure was released andthe reaction vessel was stirred for the desired time at controlledtemperature under a dihydrogen atmosphere at 1 bar. Alterna-tively, after venting the H2pressure used for the catalyst activation,the residual H2was purged with argon by continuous flushingbefore continuing the reaction. The pure products were obtainedby chromatography of the reaction mixture on silica gel using dichloromethane as eluent and then analyzed by NMR spectrosopyand chiral GC for the determination of the yields and enantiomeric excesses.

4.6. General procedure for the addition of ZnR2 to aldehydes General procedure: The Ni complex (0.1 equiv) was dissolved in anhydrous toluene(10 mL) in a Schlenk tube. The solution was stirred and cooled at0 C for 30 min, and then a solution of Et2Zn (1.1 M in toluene) orMe2Zn (1.0 M in toluene) (12 equiv) was added dropwise via a syringeunder N2 atmosphere. After stirring the mixture for 30 min atroom temperature, a solution of aldehyde (10 equiv) in dry toluenewas added dropwise via a syringe. The mixture was stirred at roomtemperature for 8 h, quenched with 1 M HCl aqueous (5 mL), andthe product was extracted into Et2O (310 mL). The combinedextracts were washed with KHCO3, dried with anhydrous MgSO4,and evaporated under vacuum. Purification by column chromatography(silica gel, 9:1 hexane/AcOEt as eluent) gave the pure alcoholas a colorless oil. All reactions were carried out using0.1e0.2 mL of aldehyde.

The conversion and the selectivity of thereaction were determined by NMR spectroscopy, and the enantioselectivitywas determined by HPLC or GC on a chiral stationaryphase Stage 1: With C32H34N4NiO2 in toluene, Time= 0.5h, T= 0 - 20 °C , Inert atmosphere, Schlenk technique Stage 2: in toluene, Time= 14h, T= 20 °C , Schlenk technique, Inert atmosphere, Solvent, enantioselective reaction Escorihuela, Jorge; Altava, Belen; Burguete, M.

General procedure for the green resolution of chiral alcohols General procedure: A 25 ml round-bottom flask was charged with 1 mmol racemic secondary alcohol, 5 mL vinyl acetate. Then 10 mg of immobilized enzyme was added in the previous mixture. When this was completed, the resulting mixture was stirred at ambient temperature for a certain time. Conversions and ee values were determined by GC analysis or HPLC analysis. When the reaction was complete, the solution was filtered through a pad of cotton; the solvent and the unreacted vinyl acetate were removed in vacuum. The resulting residues were purified by chromatography on silica gel with petroleum ether-ethyl acetate (1:10-1:5) to afford the corresponding pure (R)-configured esters.

The mixture was swirled, left at room temperature for 1 hour, quenched by rapid addition of 0.25 mL of methanol, and left for one more hour. The reaction mixture was diluted with CH2Cl2, washed twice with 1 M HCl, then twice with saturated aqueous NaHCO3, and dried over Na2SO4. The solution was concentrated on a rotary evaporator at room temperature and chromatographed (5-20percent Et2O in hexanes) to separate the ester from the unreacted alcohol.; The reaction time is expressed in hours and is shown under t(h). Entries 14 in Table 1 were obtained using 20 mol percent of the catalyst in deuterated chloroform CDCl3 at room temperature for 1 hour, and entries 5-14 were obtained using 2 mol percent of the catalyst at 0° C. in the presence of N,N-diisopropylethylamine in chloroform CHCl3 for the specified period of time. The esters produced and the unreacted alcohols resulting from kinetic resolution experiments were analyzed by chiral HPLC to determine their enantiomeric excesses (see below). HPLC analyses were performed on a Breeze LC system (Waters Corporation) and CHIRALCEL OD-H analytical column (4.6x250 mm, Chiral Technologies, Inc.) using isopropanol-hexanes mobile phase at a flow rate of 1 mL/min and UV detection at 254 nm. Specific optical rotations were measured using a Perkin-Elmer 241 polarimeter. The absolute chirality of the esters and alcohols obtained by kinetic resolution was determined by the sign of the optical rotation of the unreacted alcohol.; Procedure B: Variation of the solvent 1) The stock solution of the catalyst was prepared by dissolving 0.040 mmol of 2d (10.6 mg) and 1.5 mmol of N,N-diisopropylethylamine (262]L, 194 mg) in the reaction solvent in a 2 mL volumetric test tube and bringing the volume to the mark. 2) A one-dram vial was charged with 0.5 mmol of (O)-phenyl ethyl carbinol and 0.500 mL of the stock solution of 2d cooled in an ice bath.
