A variety of N-aryl beta-nitroenamines were effectively transformed into 3-nitroindoles in good yields and with complete regioselectivity via a rapid microwave (mu V) assisted intramolecular arene alkene coupling reaction. This report further demonstrates the versatility of this method by constructing 3-carboalkozy- and 3-cyanoindoles. Optimization data, substrate scope, and applications are discussed.
