The selective acylation of indoles often requires sensitive and reactive acyl chloride derivatives. Here, we report a mild, efficient, functional group tolerant, and highly chemoselectiveN-acylation of indoles using thioesters as a stable acyl source. A series of indoleamides have been obtained with moderate to good yields. In addition, heterocycles, such as carbazole, can also be used as nucleophiles

Abstract The N-acylation of indoles has been accomplished via inorganic base catalysis. It provided an efficient and simple catalysis system for the preparation of N-acylindoles with alkenyl carboxylates as acylating agents. A broad variety of indoles undergo the smooth N-acylation using Na2CO3 as catalyst in MeCN at 120 °C to give the corresponding N-acylindoles in good to excellent yields. The N-acylation
摘要 吲哚的N-酰化已经通过无机碱催化完成。它为以链烯基羧酸盐为酰化剂制备N-酰化吲哚提供了有效而简单的催化体系。使用Na 2 CO 3作为催化剂在MeCN中于120°C对多种吲哚进行平滑的N-酰化反应,从而以良好或极好的收率得到相应的N-酰基吲哚。 吲哚的N-酰化已经通过无机碱催化完成。它为以链烯基羧酸盐为酰化剂制备N-酰化吲哚提供了有效而简单的催化体系。使用Na 2 CO 3作为催化剂在MeCN中于120°C对多种吲哚进行平滑的N-酰化反应,从而以良好或极好的收率得到相应的N-酰基吲哚。
