A novel strategy for intercepting the σ-alkylpalladium species generated via a Heck reaction, enabling a palladium-catalyzed cyclization of o-ethynylanilines, has been described. This direct and operationally simple protocol provided a fundamental platform to synthesize bisindoles with high efficiency, involving one C–N bond and two C–C bond formations.
已经描述了用于拦截经由Heck反应产生的σ-烷基钯种类的新策略,该策略使得钯能够催化邻乙炔基苯胺的环化。这种直接且操作简单的方案为高效合成双吲哚提供了基础平台,涉及一个C–N键和两个C–C键形成。
