Fe/ZSM-5-catalyzed-synthesis of 1,4-dihydropyridines under ultrasound irradiation and their antioxidant activities
A small library of 1,4-dihydropyridines have been synthesized from ethyl acetoacetate, ammonium acetate and various aldehydes via Hantzsch multicomponent reaction in the presence of Fe/ZSM-5 catalyst under ultrasound irradiation for 90 min. 1,4-Dihydropyridine derivatives were obtained in 64-86% yie...
