A concerted palladium catalyzed C−H activation and decarboxylative strategy has been explored for the efficient synthesis of N-acylated indoles. The process allows a facile step- and atom-economic assembly of 3-arylated indole ring from inexpensive and readily available anilides and cinnamic acids as reacting partners.

钯通过邻位C-H活化和脱羧策略催化C-C和C-N键形成：一种N-酰化吲哚的实用方法

为有效合成N-酰化的吲哚，人们探索了一种协同的钯催化的CH活化和脱羧策略。该方法允许以廉价且容易获得的酸酐和肉桂酸作为反应伙伴，容易地以步骤和原子经济的方式组装3-芳基化的吲哚环。
