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.
Pseudomonas fluorescens lipase (PFL) was used as catalyst for enzymatic resolution of 1-ethoxycarbonyl-2-hydroxy-cyclohexane. The resulting ester was used for the total synthesis of the novel enantiomerically pure 10-ethyl trinem. (C) 1997, Elsevier Science Ltd.

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.
