The [5–6–7] azatricyclic ABC core, found in several Daphniphyllum alkaloids, has been synthesized through a novel route involving ring expansion of a perhydroindolone to afford the AC ring system and a radical B ring closure as key steps. The level of functionalization of the reported octahydro-1,7-ethanocyclohepta[b]pyrroles suggests that they can serve as valuable building blocks in this alkaloid
在几种瑞香生物碱中发现的[5-6-7]氮杂三环ABC核心是通过一种新途径合成的,其中包括全氢吲哚酮的扩环以提供AC环系统和自由基B环闭合作为关键步骤。已报道的八氢-1,7-乙醇环庚[ b ]吡咯的官能化水平表明它们可以作为该生物碱领域的有价值的构建模块。还报道了通过 2-氮杂双环[3.3.1]壬烷扩环首次合成同吗啡烷。
