A brief introduction into the chemistry of the CP-molecules is followed by first-generation synthetic sequences toward key building blocks for their total synthesis. Processes for both racemic and enantiomerically enriched bicyclo[4.3.1] ketone 6 or its equivalent are described, and the absolute stereochemistries of the optically enriched intermediates are determined. The efficient route developed
简要介绍 CP 分子的化学,然后是第一代合成序列,以了解其全合成的关键构建模块。描述了外消旋和对映体富集的双环 [4.3.1] 酮 6 或其等效物的过程,并确定了光学富集的中间体的绝对立体化学。开发到外消旋 6 的有效途径和关键构件的两种对映异构体的容易获得,为 CP 分子的全合成和绝对立体化学的测定提供了机会。
