Abstract
The 7-azabicyclo[4.3.1]decane ring system, common to a number of biologically active alkaloids, was accessed from tropone (via its η4-diene complex with Fe(CO)3) in a short sequence of steps: 1) nucleophilic amine addition and subsequent Boc-protection, 2) photochemical demetallation of the iron complex, and 3) an intramolecular Heck reaction. Minor modifications to the protocol enabled access to the related 2-azabicyclo[4.4.1]undecane system, albeit in lower yield.

通过分子内 Heck 反应从三羰基(托酮)铁合成 7-氮杂双环[4.3.1]癸烷环系统
摘要
7-氮杂双环[4.3.1]癸烷环系统是许多生物活性生物碱所共有的,是通过简短的步骤从托酮(通过其 η 4 -二烯与 Fe(CO) 3的复合物)获得的:1)亲核胺加成和随后的 Boc 保护,2) 铁配合物的光化学脱金属,以及 3) 分子内 Heck 反应。对方案进行少量修改即可访问相关的 2-氮杂双环[4.4.1]十一烷系统,尽管产率较低。
