実験手順
4'-Isobutylbutanophenone (1.2 g) was added to a solution of (+)-B-chlorodiisopinocampheylborane (2.10 g) in tetrahydrofuran (4 ml) at 25° C. After 5 hours, the solvent was removed and the residue was dissolved in ethyl ether (20 ml). Diethanolamine (1.4 ml) was added to the mixture and the mixture was stirred for 2 hours. The solid was filtered off and washed with ethyl ether. The combined filtrates were concentrated and the residue was chromatographed on silica gel (eluent:hexane:CH2Cl2 =1:2) to give (R)-1-(4-isobutylphenyl)butan-1-ol (937 mg).
