  Candida Rugosa lipase-catalyzed kinetic resolution of β-hydroxy-β-arylpropionates and δ-hydroxy-δ-aryl-β-oxo-pentanoates

  摘要：

  A simple and convenient method was reported for the preparation of optically active beta-hydroxy-beta-arylpropionates, delta-hydroxy-delta-aryl-beta-oxo-pentanoates and their butyryl derivatives via CRL-catalyzed hydrolysis. The optically active products are potential precursors of some chiral pharmaceuticals and natural products. (C) 2005 Elsevier Ltd. All rights reserved.
