processes that mostly trigger rearrangements of the methanoquinolizidine motif. The family of the akuammiline alkaloids is best represented by strictamine. It bears the least functionalized carbon skeleton of all family members without lacking the signature structural motifs. Herein, we report the formal synthesis of strictamine through a Stevens [2,3]‐sigmatropic rearrangement as a key step and the synthetic
迄今为止,已经分离出了100多个阿库米林生物碱家族的同源物。它们的标志性结构元素是甲亚甲基喹唑烷部分,这是一种与金刚烷在结构上相关的笼状支架。该家族成员的结构变异来自氧化过程,该氧化过程主要触发了甲基喹啉嗪基序的重排。akuammiline生物碱家族最好以严格胺为代表。它具有所有家族成员中功能化程度最低的碳骨架,且不缺少标志性的结构图案。在本文中,我们报告了通过史蒂文斯[2,3]-σ重排作为关键步骤进行的正丁胺的正式合成,以及与合成有关的合成陷阱。
