A concise total synthesis of (±)-myrioneurinol has been achieved in 14 steps. An efficient AgSbF /t-BuCl-catalyzed intramolecular [2+2] cycloaddition reaction of the alkynone-tethered enamine was developed to prepare the highly strained cyclobutene. It was used in combination with a subsequent retro-Mannich fragmentation/Mannich reaction to efficiently construct the tricyclic core of myrioneurinol.
已通过 14 步反应实现了（±）-myrioneurinol 的简洁全合成。开发了一种有效的 AgSbF/t-BuCl 催化的炔酮-连接的烯胺的分子内[2+2]环加成反应，以制备高度应变的环丁烯。该方法与随后的逆-Mannich 断裂/Mannich 反应相结合，有效地构建了 myrioneurinol 的三环核心。
