The reaction proceeds via a nucleophilic attack of primaryamine on dialkyl acetylenedicarboxylate followed by Michael addition with β-nitrostyrene and successive intramolecular cyclization and aromatization to yield 1,2,3,4-tetrasubstituted pyrroles in good to excellent yields. A wide range of primaryamines including aromaticamines and benzylamines were coupled with differently substituted β-nitrostyrenes
