摘要：
A process for efficiently producing (S,S)-2-alkoxycyclohexanols in a single step by using (.+-.)-trans-2-alkoxycyclohexanols which are inexpensive and can be easily obtained. The process comprises treating a (.+-.)-trans-2-alkoxycyclohexanol with a hydrolase originating in a microorganism and being capable of esterifying stereospecifically the R-isomer in the presence of an acyl donor under such conditions that no hydrolysis occurs substantially to thereby give (S,S)-2-alkoxycyclohexanols and (R,R)-2-alkoxycyclohexanol carboxylate and then taking up the (S,S)-2-alkoxycyclohexanols.
