The aspidosperma alkaloid goniomitine was synthesized in six steps from 2-ethyl-δ-valerolactam. The convergent strategy features an Ullman coupling to assemble the required carbon atoms. A complexity-generating radical translocation reaction was used to build the indole architecture.
从 2-乙基-δ-戊内酰胺出发,经六步反应合成了石蒜科生物碱高尼米汀。该合成策略采用 Ullman 偶联反应来构建所需的碳原子,利用产生复杂结构的自由基迁移反应构建吲哚环系。
