    Kinetic resolution of α-bromophenylacetamides using quinine or Cinchona alkaloid salts
    摘要:
    The kinetic resolution of racemic alpha-bromophenylacetamides 1 was achieved in the presence of benzenethiolate and Cinchona alkaloid salts as phase-transfer catalysts or benzenethiol and quinine, yielding (S)-enantioenriched alpha-sulfanylated products. The observed stereoselection was rationalized on the basis of the best fitting of 1 and the resolving agent in the ternary complexes. (C) 2012 Elsevier Ltd. All rights reserved.
