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

Solvent free; 1,4-dihydropyridine; magnetic nanocomposite catalyst.
