Abstract

An efficient synthesis of Hantzsch 1,4-dihydropyridines via a one-pot three-component reaction of ethyl acetoacetate, substituted aldehydes and ammonium acetate in the presence of ZnO@SnO2 mixed metal oxide nanoparticles under solvent-free conditions has been reported. Compare to the reported reactions, this method shows attractive aspects such as cleaner reaction profile, shorter reaction times, minimum catalyst loading and high yields. Isolated catalysts were reused for new reactions without considerable loss of their catalytic activity.
