title: Manganese(IV) dioxide-catalyzed synthesis of quinoxalines under microwave irradiation.
abstract: We synthesize quinoxalines, catalyzed by manganese(IV) dioxide, from a variety of alpha-hydroxyketones followed by trapping with aromatic or aliphatic 1,2-diamines without using a solvent, within one minute under microwave irradiation.
