                                    Enantiopure (1R,2R)-, (1S,2S)-, (1S,2R)- and (IR,2S)-2-cyanocyclopentanol and -cyclohexanol, isomers were prepared through the Pseudomonas cepacia lipase-catalysed acetylation of the racemic cis and trans compounds with vinyl acetate in diisopropyl ether. The quasi-irreversible nature of acylations with 2,2,2-trifluoroethyl esters is evident. (C) 1997 Elsevier Science Ltd.
