We report the total synthesis of (±)-aspidophylline A, one of many complex furoindoline-containing alkaloids that has not been synthesized previously. Our route features a number of key transformations, including a Heck cyclization to assemble the [3.3.1]-bicyclic scaffold as well as a late-stage interrupted Fischer indolization to install the furoindoline and construct the natural product's pentacyclic framework.
我们报告了(±)-aspidophylline A 的全合成,(±)-aspidophylline A 是许多以前尚未合成的含呋喃吲哚生物碱之一。我们的路线具有许多关键的转化,包括 Heck 环化以组装[3.3.1]-双环支架,以及晚期中断的 Fischer 吲哚化以安装呋喃吲哚并构建天然产物的五环骨架。
