Kinetic resolutions of a number of beta-hydroxy selenides promoted by enzymes were performed using PPL (free Porcine pancreatic lipase), PSL (Amano PS-free Pseudomonas sp. lipase) and CALB (NOVOZYM 435(R)-immobilized Candida Antarctica lipase type B) with (RS)-1-phenylselanyl-propan-2-ol. CALB gave the best results and provided both (R)- and (S)-enantiomers in high enantiomeric purity. A comparative study of the effect of temperature, solvent, enzyme immobilization and the structure of the substrates on the resolution is presented. (C) 2004 Elsevier Ltd. All rights reserved.
