The first total synthesis of sespenine, a rare indole sesquiterpenoid from a mangrove endophyte, has been accomplished. A bioinspired aza‐Prins/Friedel–Crafts/retro Friedel–Crafts cascade reaction assembles the bridged tetrahydroquinoline core. Further investigations on the aza‐Prins cyclization imply that the C3 configuration of the hydroxyindolenine intermediate is crucial to the biosynthesis of
已经完成了从红树林内生植物中稀有的吲哚倍半萜类物质-倍半萜的第一个全合成。生物启发的氮杂-Prins / Friedel-Crafts /复古Friedel-Crafts级联反应可组装桥接的四氢喹啉核心。对aza-Prins环化的进一步研究表明,羟基吲哚烯中间体的C3构型对倍半萜及其同类产品xiamycin A的生物合成至关重要。
