Preparation of 3-Aryl-2-aminoindoles via Rhodium-Catalyzed Coupling Reaction between 2-Arylpyridines and 3-Diazoindolin-2-imines

摘要

Rhodium-catalyzed coupling reaction of 3-diazoindolin-2-imines with 2-arylpyridines, 2-phenylpyrimidines, or 1-phenylpyrazoles furnished the corresponding 3-aryl-2-aminoindoles in moderate to excellent yields. A variety of functional groups were tolerant to the reaction conditions.
