This paper is dedicated to Professor Habib Firouzabadi for his great achievements on the occasion of his 65th birthday and his retirement. A mixture of ethyl acethylenecarboxylate, various aryl aldehydes and aminoacetaldehyde dimethyl acetal in the presence of silica gel were converted to N-ethyldimethyl acetal-1,4-dihydropyridines using microwave irradiation with good yields.
