Herein, a new magnetic metal–organic frameworks based on Fe3O4 (NMMOFs) with porous and high surface area materials were synthesized. Then, NMMOFs were characterized by FT‑IR, XRD, SEM, elemental mapping, energy dispersive X‑ray (EDS), TG, DTG, VSM, and N2 adsorption–desorption isotherms (BET). Fe3O4 @Co(BDC)‑NH2 as a magnetic porous catalyst was applied for synthesis of novel fused pyridines and 1,4‑dihydropyridines with pyrazole and pyrimidine moieties as suitable drug candidates under ultrasonic irradiation. The signifcant advantages of the presented methodology are mild, facile workup, high yields, short reaction times, high thermal stability, and reusability of the described NMMOFs catalyst.
