An effective and practical palladium-catalyzedC2-acylation method was successfully developed for the synthesis of 2-acylindoles. A variety of 2-acylindoles were readily prepared from N-pyrimidyl indoles in moderate to good yields. This methodology offers several advantages, which include ease of handling, mild reaction conditions, and use of an efficient and cheap catalyst. In particular, challenging
A palladium-catalyzed decarboxylative C2-acylation of indoles with α-oxocarboxylic acids was achieved. This protocol represents a novel and complementary approach to 2-aroylindoles.
