surrounding. Some of them exhibit promising bioactivities, such as antitumor, anti‐HIV, etc. In this article, we describe our efforts to the collective total synthesis of schilancidilactones A, B, schilancitrilactones A, B, C, and 20‐epi‐schilancitrilactone A from common precursors. An intramolecular radical cyclization, late‐stage halogenation and AIBN‐mediated or Ni‐catalyzed intermolecular radical cross
五味子科的三萜类化合物是新颖的天然产物,其包含高度稠合的环系统,环系统带有多个手性中心。其中一些具有良好的生物活性,例如抗肿瘤,抗HIV等。在本文中,我们描述了我们从共同的前体中集体合成总的五聚氰基内酯A,B,Schilancitrilactones A,B,C和20- Epi- schi-schilancitrilaclactone A的努力。关键步骤包括分子内自由基环化,后期卤化和AIBN介导或Ni催化的分子间自由基交叉偶联反应。
