by copper(I) iodide in aqueous medium under ultrasound irradiation has been developed for the synthesis of a series of novel pharmacologically interesting polysubstituted 1,4-dihydropyridines. In comparison with the reported methods, our approach is expedient and offers several advantages such as: a shorter reaction time, excellent yields, milder conditions, convenience and environmental benignity.
