SYNTHESIS OF HANTZSCH 1,4-DIHYDROPYRIDINES UNDER MICROWAVE IRRADIATION

Abstract
Biologically active substituted 1,4-dihydropyridines have been synthesized in excellent yields by the reaction of aldehydes, ethyl or methyl acetoacetic ester and ammonium acetate under microwave irradiation (MWI) within 0.75–3 min.
