Gold-catalyzed oxidation of arylallenes: Synthesis of quinoxalines and benzimidazoles.

ABSTRACT: A gold-catalyzed oxidation of arylallenes to form α-diketones and aldehydes in good yields is presented. Further directed synthesis of quinoxalines and benzimidazoles, via the condensation of the resulting α-diketones and aldehydes with benzene-1,2-diamine, was achieved in high yields.
