Abstract
A variety of 2,3-disubstituted quinoxalines are readily prepared in high yields under extremely mild conditions by cyclocondensation of arene-1,2-diamines with 1,2-dicarbonyls using a catalytic amount of bismuth(III) triflate. The reactions of 2,3-di-aminopyridine with 1,2-dicarbonyls produce pyrido[2,3-b]pyrazine derivatives under similar conditions.
