(S)-4-Hydroxy-2,2-dimethyl-1-cyclohexanone (1a) was prepared by two enzymatic methods. 1,4-Cyclohexanediol was converted to monoacetal (11) via (+/-)-1a.Enzymatic reduction of 11 by baker's yeast gave (S)-1 of almost 100 percent e.e.Direct hydroxylation of 2,2-dimethyl-1-cyclohexanone (14) by P-450 camphor monooxygenase of the cloned genes of Pseudomonas putida PpG1 gave (S)-1a of almost 100 percent e.e., too.According to Mitsunobu's method, SN-2 inversion of (S)-1 gave (R)-1.
