Abstract
(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% ee 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% ee, too. According to Mitsunobu's ...
