Abstract

A novel and efficient procedure for the synthesis of N-substituted phenanthridinones via palladium-catalyzed annulation of benzynes with N-substituted-N-(2-halophenyl)formamides has been developed. This methodology constructs two new C-C bonds via an arylation/annulation process, and provides the desired products in good yields.

摘要

通过钯催化苯炔与N-取代-N-(2-卤苯基)甲酰胺的环化反应合成N-取代菲啶酮的一种新颖且高效的方法已被开发出来。该方法通过芳基化/环化过程构建了两个新的C-C键,并以良好的产率提供所需产物。
