Abstract
2,3-Dihydroquinazolin-4(1H)-one derivatives were synthesized via a one-pot, three-component reaction of isatoic anhydride and an aromatic aldehyde with 4-aminohippuric acid, catalyzed by acetic acid. After completion of the reaction, the corresponding products were reacted with an aromatic aldehyde, acetic anhydride, and sodium acetate to yield oxazolone derivatives. The reactions were carried out under microwave irradiation and reflux.
