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.
