  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.

• Construction of Two Vicinal Quaternary Carbons by Asymmetric Allylic Alkylation: Total Synthesis of Hyperolactone C and (−)-Biyouyanagin A
  作者：Chao Du、Liqi Li、Ying Li、Zhixiang Xie

  DOI：10.1002/anie.200902908

  日期：2009.10.5

  Call on triple A: Palladium‐catalyzed asymmetric allylic alkylation (Pd‐AAA; see scheme) has enabled a concise and efficient synthesis of hyperolactone C and (−)‐biyouyanagin A in only six (20 % overall yield) and seven (8 % overall yield) steps, respectively. The enantiomers of these natural products were also prepared by exploiting the same methodology.
