Procedure: To a stirring suspension of 1.20 g of lithium aluminum hydride in 100 mL of diethyl ether under an argon atmosphere at 0° C. is slowly added a solution of 4.40 mL of commercially available valerophenone in 5.0 mL of diethyl ether over 10 minutes. After 0.5 hours the grey suspension is warmed to room temperature. After 1 hour the reaction mixture is re-cooled to 0° C. and slowly treated with 1.25 mL of water followed by 5.50 mL of 1N sodium hydroxide. After 1 hour the resulting white precipitant is filtered through a pad of magnesium sulfate with diethyl ether washings. The filtrate is concentrated under reduced pressure to afford 4.5 g of 1-phenyl-1-pentanol as a clear, colorless oil. This product may be used directly in the next reaction without further purification. After 1 hour the reaction mixture is re-cooled to 0° C. After 1 hour the resulting white precipitant is filtered through a pad of magnesium sulfate with diethyl ether washings The filtrate is concentrated under reduced pressure

Conditions: temp:140.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: Tris(triphenylphosphine)ruthenium (II) chloride (1.9 mg, 2 μmol, 0.5 mol %) and a chiral ligand (M=Ru, R=i-Pr, Ar=C6H5—, 1.3 μmol, 0.33 mol %) were dissolved in xylene (3 mL) under nitrogen atmosphere, and then heated and stirred for 1 h at 140° C. After the mixture was cooled to room temperature, pentanophenone (0.4 mmol), xylene (2 mL) and a solution of potassium hydroxide in methanol (0.4 mL, 0.2 M) were added thereto. Thereafter, the reaction system was placed in an autoclave, and stirred for 12 h under H2 (10 atm) at 25° C. The solvent was removed under reduced pressure, and the resultants were separated by column chromatography (silica gel column; eluent:ethyl acetate/petroleum ether=1/8). Accordingly, pure 1-phenylpentanol was obtained and the ee value (ee=99.6%) was measured by GC analysis. heated After the mixture was cooled to room temperature stirred for 12 h under H2 (10 atm) at 25° C The solvent was removed under reduced pressure the resultants were separated by column chromatography (silica gel column; eluent:ethyl acetate/petroleum ether=1/8)
