摘要：
Rhodium-catalyzed reactions of 3-diazoindolin-2-imines with aromatic aldehydes and ?±,??-unsaturated aldehydes respectively furnished (E)-2-aminomethylene-3-oxoindoles and pyranoindoles in moderate to excellent yields with nice functional group tolerance. The reaction proceeds in a cascade involving ?±-amidino rhodium carbene as the key intermediate.
