A concise approach toward the total synthesis of the communesin alkaloids and perophoramidine is reported. The strategy relies on the use of the interrupted Fischer indolization to build the tetracyclic indoline core of the natural products. Studies to probe the scope and limitations of this plan are presented. Although the methodology does not tolerate a C8-allyl substituent en route to the challenging
报告了一种对公社生物碱和 perophoramidine 全合成的简明方法。该策略依赖于使用中断的 Fischer 吲哚化来构建天然产物的四环二氢吲哚核心。介绍了探讨该计划的范围和局限性的研究。尽管该方法不能容忍 C8-烯丙基取代基到具有挑战性的邻位四元立体中心,但允许在 C7 和 C 环上发生变化。
