Polyheterocycles are found in many natural products and are useful moieties in functional materials and drug design. As part of a program towards the synthesis of Stemona alkaloids, a novel palladium(II)‐catalyzed CH activation strategy for the construction of such systems has been developed. Starting from simple 1,3‐dienyl‐substituted heterocycles, a large range of polycyclic systems containing pyrrole
多杂环存在于许多
天然产物中,并且在功能材料和药物设计中是有用的部分。作为合成花粉
生物碱的计划的一部分,已经开发了一种新型的
钯(II)催化的CH活化策略来构建此类系统。从简单的1,3-二烯基取代的杂环开始,可以一步合成大量包含
吡咯,
吲哚,
呋喃和
噻吩部分的多环系统。
