A simple and efficient method for the preparation of racemic 4-aryloxy-3-hydroxybutanenitriles is described, Lipase mediated kinetic resolution in organic media was then utilised to effect enantioseparation. Lipases from different sources were screened in the resolution reaction using a number of organic solvents. Enantiomeric excesses of up to 99%, were obtained by employing lipase from Pseudomonas cepacia in di-iso-propyl ether medium. (C) 2001 Elsevier Science Ltd. All rights reserved.
