A series of quinoxaline derivatives was synthesized by the reaction of 3-(Ï-bromoacetyl)coumarins with substituted 1,2-diaminobenzenes in the absence of a catalyst under microwave conditions. Reasonable yields of the products, environmentally benign and convenient workup are the advantages of this method.
