YieldReaction ConditionsOperation in experiment
75% With dimethylsulfide borane complex; C23H22BNO3 In tetrahydrofuran at 20℃; for 2 h; Cat-5 (0.05 mmol, 20 mg) prepared in Preparation Example 2.5 was dissolved in 1 ml of THF, BH3-DMS (0.42 mmol, 0.04 ml) was added, and the mixture was stirred for about 7 minutes. A solution of 3-chloropropiophenone (0.6 mmol, 100 mg) in 0.45 ml of THF was added dropwise to the reaction mixture. After reacting at room temperature for 2 hours, the reaction was terminated by the addition of methanol. (R) -3-chloro-1-phenylpropanol (yield: 75percent, 73percent ee) was obtained in the same manner as in Example 1.1.
77 % ee With hydrogen In methanol at 60℃; for 24 h; 6.127 mg (8.0 μmol) of Cp*Ir(OTf)[(S,S)-MsDPEN] and 1.249 g (8.0 mmol) of β-chloropropiophenone were introduced in an autoclave, and the mixture was subjected to argon substitution. 3.3 mL of methanol was introduced and deaeration was performed, then hydrogen gas was introduced at 10 atm and the resulting mixture was maintained at 60° C. for 24 hr while stirring. The solvent was distilled off under reduced pressure to give a crude product. GC analysis of the reactant confirmed that 3-chloro-1-phenylpropane-1-ol with optical purity of 77percent ee was produced in 12percent yield. Comparison with Example E-1 demonstrated the superiority of the asymmetric reduction using a potassium formate solution as the hydrogen source.
80 % ee With dimethylsulfide borane complex; (1R,2S,3R,5R)-2-(1',3',2'-dioxaborolan-2'-yloxy)apopinan-3-amine In tetrahydrofuran at 20℃; for 1 h; General procedure: To a solution of 1 (0.005–0.01 mmol, 0.5–1 mol percent) in dry THF(3 mL) at room temperature, a solution of BH3SMe2 (10 M,100 lL, 1 mmol) in THF (2 mL) was added dropwise at a rate of3.2 mL per hour using a syringe pump. At the same time a solutionof ketone (1 mmol) in THF (2 mL) was also added to the reactionflask at a rate of 3 mL per hour. After the addition of both reagents,the reaction mixture was stirred for 20 min, quenched by the additionof MeOH (1 mL) at room temperature, and stirred for 30 min. Subsequently, the solvents were evaporated under vacuum and theproduct was isolated by column chromatography using hexane/EtOAc (4:1) as the eluent.
66 % ee at 20℃; for 20 h; General procedure: A flask was charged with azolium salt L12 (0.02 mmol, 9.1 mg),Ag2O (0.01 mmol, 2.4 mg) and CH2Cl2(1 mL). After stirring the resulting mixture at room temperature for 2 h in the dark, CH2Cl2 was removed in vacuo. Then, a THF (1 mL) solution of [IrCl(cod)]2(0.01 mmol, 6.9 mg) was added to the reaction vessel. The resulting mixture was stirred at room temperature for an additional 4 h in the dark, filtered through a membrane filter, and evaporated to dry-ness in vacuo. Subsequently, to the resulting flask containing yellow solid of the unpurified IrCl(cod)(NHC) complex, a solution of AgBF4(0.025 mmol, 4.9 mg) in CPME (2 mL) was added, and then stirred at room temperature for 1 h. Finally, propiophenone (0.5 mmol,66 mg) and (EtO)2MeSiH (2.25 mmol, 294 mg) were added to the resulting CPME solution (see Appendix A. Supplementary data fordetails). After stirring at room temperature for 20 h under open-air conditions, K2CO3(2 mg) and MeOH (2 mL) were added. Then, the resulting mixture was stirred at room temperature for 2 h. Afterevaporation of the solvents, the residue obtained was purified bycolumn chromatography on silica gel (Et2O/n-hexane = 3:7) to give(S)-1-phenyl-1-propanol (61 mg, 91percent isolated yield). The ee was measured by chiral GLC.

88 % ee With Burkholderia species lipoprotein lipase; C51H77NO17; dextrin In toluene at 25℃; for 6 h; Enzymatic reaction General procedure: In a typical procedure, isopropenyl acetate (1.5 equiv.) was added to a 4 mL-vial containing BSLPL-1c-D (3 mg), substrate (0.3 mmol), and anhydrous toluene (0.5 M). The resulting solution was then shaken at 25 °C until the reaction reached 46–50percent conversion. After being diluted with methylene chloride, the reaction mixture was filtered through a celite pad, concentrated, and then analyzed by HPLC to determine the enantiomeric excesses of remaining substrate and acetylated product. The enantioselectivity (E) was then calculated using the equation: E = ln[1−c(1+eep)]/ln[1−c(1−eep)] where c = ees/(ees+eep). The kinetic resolution of 4a: (S)-4a (82percent ee) and (R)-5a (97percent ee); 46percent conversion; E = >100. The kinetic resolution of 4b: (S)-4b (>99percent ee) and (R)-5b (97percent ee); 50percent conversion; E=>100.

88 % ee With Burkholderia species lipoprotein lipase; C51H77NO17; dextrin In toluene at 25℃; for 6 h; Enzymatic reaction General procedure: In a typical procedure, isopropenyl acetate (1.5 equiv.) was added to a 4 mL-vial containing BSLPL-1c-D (3 mg), substrate (0.3 mmol), and anhydrous toluene (0.5 M). The resulting solution was then shaken at 25 °C until the reaction reached 46–50percent conversion. After being diluted with methylene chloride, the reaction mixture was filtered through a celite pad, concentrated, and then analyzed by HPLC to determine the enantiomeric excesses of remaining substrate and acetylated product. The enantioselectivity (E) was then calculated using the equation: E = ln[1−c(1+eep)]/ln[1−c(1−eep)] where c = ees/(ees+eep). The kinetic resolution of 4a: (S)-4a (82percent ee) and (R)-5a (97percent ee); 46percent conversion; E = >100. The kinetic resolution of 4b: (S)-4b (>99percent ee) and (R)-5b (97percent ee); 50percent conversion; E=>100.
