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.
