Hydrolysis of racemic acetates with Pseudomonasfluorescenslipase (PFL) afforded optically active alcohols with the R-configuration, independent of ring size; a three-site model for PFL-catalysed hydrolysis is proposed.

Lipases A and B from Candida antarctica are shown to be highly efficient and complementary biocatalysts for the resolution of five- to seven-membered cyclic beta-hydroxy esters by O-acylation. Using this procedure, all four stereoisomers of each one are obtained in enantiopure form and very high yields. (C) 2003 Elsevier Science Ltd. All rights reserved.
