Abstract: An efficient synthetic protocol for the 1,4-diaryl-1,4-dihydropyridines was developed via the domino four-component reaction of arylamine, acetylenedicarboxylate, aromatic aldehyde and ethyl acetoacetate. The reaction mechanism involves the formation of β-enamino ester and its sequential Michael addition to arylidene acetoacetate.

Key words: 1,4-Dihydropyridine, β-Enamino ester, Domino reaction, Four-component reaction
