A total synthesis of aspidophylline A, a pentacyclic akuammiline‐type monoterpene indole alkaloid, is described. The synthesis features: 1) rapid access to a fully functionalized dihydrocarbazole through the desymmetrization of readily available 2‐allyl‐2‐(o‐nitrophenyl)cyclohexane‐1,3‐dione; 2) an intramolecular azidoalkoxylation of an enecarbamate to install both the furoindoline ring and the azido
介绍了五环茶氨酰胺型单萜吲哚生物碱-阿斯匹多碱A的全合成。合成特征:1)通过对现成的2-烯丙基-2-(邻硝基苯基)环己烷-1,3-二酮进行脱对称处理,快速获得功能齐全的二氢咔唑;2)烯内酰胺的分子内叠氮基烷氧基化以同时安装呋喃二氢吲哚环和叠氮基官能团;3)用于2-氮杂双环[3.3.1]壬烷环系统的分子内迈克尔加成。
