Abstract
Sulfonic acid-supported vanillin/bis indolylmethane-functionalized Fe3O4@SiO2-Propyl NPs were prepared and characterized by FT-IR, XRD, FE-SEM, TEM, VSM, EDX, DLS, and TGA-DTG. The catalytic efficiency of the prepared nanoparticles was subsequently investigated for the effective synthesis of imidazoquinazolines via the one-pot condensation of 2-aminobenzimidazole, aryl aldehydes, and cyclohexanone or dimedone under solvent-free condition. Some thiazoquinazolines also were prepared via the multicomponent reaction of aldehydes, dimedone, and 2-aminobenzothiazol under solvent-free condition,. This avenue is really suitable because it makes a high yield of product, doesn’t take too long, doesn’t need harmful materials and solvents, its work-up is easy and the catalyst is reusable.
