A straightforward approach to a highly functionalized enantioenriched bicyclo[5.3.0]decadienone system close to the thapsigargin framework has been achieved. The developed synthetic route involves two main stages: installation of the chains on either side of the quaternary center at C7 starting from a central enantiopure epoxide and formation of the bicyclic octahydroazulene through subsequent Pauson–Khand annelation.
已成功实现一种直接合成高度功能化的手性富集双环[5.3.0]癸二烯酮的方法,该化合物接近thapsigargin骨架。所开发的合成路线包括两个主要阶段:以中心手性纯环氧�苷为起始物,在C7季碳中心两侧安装链段;通过随后的Pauson-Khand环化反应形成双环八氢蔚蓝烯结构。
