  Studies on the chemoenzymatic synthesis of 3-phenyl-GABA and 4-phenyl-pyrrolid-2-one: the influence of donor of the alkoxy group on enantioselective esterification

  摘要：

  A new chemoenzymatic method for the synthesis of enantiomerically pure 3-phenyl-gamma-aminobutyric acid 1 and 4-phenyl-pyrrolid-2-one 9 based on the enzymatic kinetic resolution of 3-phenyl-4-pentenoic acid 2 is described herein. Enzymatic resolution of the racemic substrate provided products with good enantiselectivity upon esterification. In these reactions, a new class of alkoxy group donor-orthoesters, acetals and ketals were used. The best results of the enzymatic kinetic resolution were obtained for triethyl orthoacetate in toluene solvent. Crown Copyright (C) 2013 Published by Elsevier Ltd. All rights reserved.
