A supported magnetic nanocomposite as a simple, stable, and efficient catalyst was successfully developed for condensation reaction of aldehydes, ammonium acetate, and isatoic anhydride to prepare 2,3-dihydroquinazolin-4(1H)-one derivatives as essential biologically active heterocyclic compounds. Ethanol as a non-toxic solvent under a reflux condition was utilized in the reactions. The Fe3O4/SiO2/CeO2 nanocomposite was prepared as a […]
