A variety of dihydroquinazolin-4(1H)-one derivatives (1–37) were synthesized via “one-pot” three-component reaction scheme by treating aniline and different aromatic aldehydes with isatoic anhydride in the presence of acetic acid. Chemical structures of c

Hydroxyapatite nanoparticles (HAP NPs) are found to be an efficient catalyst for synthesis of 2,3-dihydroquinazolin-4(1H)-one derivatives in aqueous media via a three-component one-pot condensation of isatoic anhydride and aromatic aldehydes with primary amines or ammonium salts. The nanocatalyst (characterized by FT-IR, XRD, SEM-EDS and TEM techniques) is easily recyclable six times without the significant loss of catalytic activity. Other remarkable features include the wide range of functional group tolerance and good to excellent yields of the products under mild reaction conditions.

A CuO nanoparticle-catalyzed one-pot process has engineered for the preparation of diverse quinazolinones from the readily available isatoic anhydride, aldehydes and amine or ammonium. For amine substrates the reactions afford 2,3-dihydroquinazolin-4(1H)-ones in aqueous ethanol promoted by ultrasound irradiation. However, the ammonium substrates undergo intramolecular electron transfer and rearrangement yielding quinazolin-4(3H)-ones. The catalyst is recyclable four times without loss of substantial activity. Other remarkable features include the wide range of functional group tolerance (46 quinazolinones are synthesized and 9 of them are reported firstly), and providing moderate to excellent yield of the products under mild conditions.
