Abstract

Over the past few years, the use of palladium-catalyzed aromatic carbon–nitrogen bond forming reactions by the cross-coupling of aryl halides or triflates and amines has become a useful synthetic tool. Herein, we describe a copper (I) catalyst system that allows efficient synthesis of functionalized indoles and pyrrolo [2, 3-c] pyridines. This method takes advantage of amino acid promoted copper coupling of amines with aryl halides, in ...
