• β‐Ketoesters as Mono‐ or Bisnucleophiles: A Concise Enantioselective Total Synthesis of (−)‐Englerin A and B
  作者：Lei Guo、Bernd Plietker

  DOI：10.1002/anie.201900401

  日期：2019.6.17

  A short enantioselective total synthesis of englerin A, a guaiane sesquiterpene with significant in vitro antitumor activity, is reported. Key features of this total synthesis are an organocatalytic asymmetric decarboxylative aldol reaction, a neighboring‐group‐participating [4+3] cycloaddition, a novel one‐pot Heck coupling/regioselective 1,4‐hydrosilylation/Tamao–Fleming oxidation cascade, and a

  据报道，一种短时的对映体全合成的englerin A是一种具有显着的体外抗肿瘤活性的愈创树倍半萜烯。该总合成的关键特征是有机催化不对称脱羧醛醇醛反应，邻基参与的[4 + 3]环加成反应，新颖的单锅Heck偶联/区域选择性1,4-氢化硅烷化/ Tamao-Fleming氧化级联反应以及降低CBS的动力学，从甲基乙二醛开始的十二个步骤中，生成的光学纯天然产物的总收率为6.7％。englerin A的更具反应性的乙醇酸酯部分的选择性皂化也产生（-）-englerinB。
