one-pot synthesis of 1,4-dihydropyridine derivatives using magnetic nanocomposite catalyst under solvent-free conditions

a green and efficient synthesis of hantzsch 1,4-dihydropyridine derivatives using magnetic nanocomposite (fe₃o₄-ch-so₃h) as a recyclable catalyst under solvent-free conditions was performed. the catalyst was characterized by ft-ir, vsm, and sem analysis. one-pot three-components hantzsch synthesis 1,4-dihydropyridine derivatives using magnetic nanocomposite has the advantages of short reaction times, little catalyst loading, high yields, easy recovery and reusability of the catalyst.
