Nanosized MgO as a Heterogeneous Base Catalysts, Catalyses Multicomponent Reaction of Cyclic Enaminoketones, Malononitrile, and Aromatic Aldehydes

Abstract

Nanosized MgO is an efficient catalyst for the synthesis of 1,4-dihydropyridine and imidazo[1,2-a]quinoline derivatives from multicomponent reaction of cyclic enaminoketones, malononitrile and aromatic aldehydes in EtOH at reflux condition. This method provides several advantages such as mild reaction and high yield with short reaction time.
