| Abstract: | Tetraacetylethylene ( 1 ), and cis-diacetylethylene ( 4 ) reacted under mild conditions with 3-amino-2-butenoic acid methyl ester ( 6 ), benzene-1,2-diamine and naphthalene-2,3-diamine to give polysubstituted pyrroles, 2,3-disubstituted quinoxalines and 2,3-disubstituted benzo[g]quinoxalines respectively. Some aspects of the reactions mechanisms are discussed. |
