Magnetic nanoparticles (MNPs), through extraordinary capability for instance non-toxicity, retrievability and accessibility have become a vital part of heterogeneous catalysis. Catalysts which have benefited with this kind of supports, supply appropriate conditions to affixing organic linkers [1,2]. A huge range of heterocyclic compounds have been prepared by multicomponent reactions (MCRs) which offering multidimensional pharmaceutical applications [3]. In this study, in the continuation of our research in this field we attempted to synthesize some novel and complex hybrid pyridines incorporated triazole, indole or sulfonamide moieties by using a magnetic H-bonding catalyst which is based on Fe3O4@SiO2
