Abstract

An efficient and ecofriendly procedure for the onepot synthesis of biologically active heterocyclic compounds including indazolo12bphthalazinetriones has been developed in the presence of Fe3O4SiO2 nanoparticles The multicomponent reactions of aldehydes dimedone and phthalhydrazide were carried out under solventfree conditions to obtain some indazolo12bphthalazinetrione derivatives The present approach provides several advantages such as excellent yields a simple workup low reaction times easy catalyst separation and little catalyst loading
