Desymmetrisation of 4-cyano-4-phenylcyclohexanone 1 has been achieved by enzyme-catalysed enantioselective alcoholysis with n-butanol of the derived racemic enol acetate 2 in tetrahydrofuran. The absolute configuration of the enol acetate (−)-(S)-2 (100% e.e.) obtained was determined by X-ray analysis of the camphanyl derivative 7.
