  描述：

  (E,9S,13S)-9,12,13-tris[[tert-butyl(diphenyl)silyl]oxy]octadec-10-enoic acid 在 四丁基氟化铵 作用下， 以 四氢呋喃 为溶剂， 反应 12.0h， 以89%的产率得到(9S,12RS,13S)-pinellic acid
  参考文献：
  名称：

  A chemoenzymatic asymmetric synthesis of (9S,12S,13S)- and (9S,12RS,13S)-pinellic acids

  摘要：

  A brief and facile synthesis of the title compounds has been developed by using an efficient lipase-catalyzed acylation and a chiral template-directed diastereoselective alkylation for incorporating the stereogenic centres. A cross-metathesis was employed to get the required E-olefin geometry. (C) 2009 Elsevier Ltd. All rights reserved.
