A Regiocontrolled Synthesis of Substituted Indoles by Palladium-Catalyzed Coupling of 2-Bromonitrobenzenes and 2-Bromoacetanilides

Kasahara, Akira,Izumi, Taeko,Murakami, Satoshi,Miyamoto, Kazuhiro,Hino, Toshimi

, p. 1405 - 1413 (2007/10/02)

The palladium-catalyzed cross-coupling reaction of 2-bromonitrobenzenes or 2-bromoacetanilides with ethylene has been used to produce a variety of substituted indoles.The mild reaction conditions and selectivity inherent in the coupling reaction have been utilized to produce regiochemically pure 4-, 5-, 6-, and 7-substituted indoles.
