ABSTRACT An efficientsynthesis of 2,3-dihydroquinazolin-4(1H)-one derivatives is accomplished in aqueousmedia by a three-component reaction of isatoic anhydride, primary amines or ammonium acetate, and aldehydes catalyzed by titanium silicon oxide nanopowder. A variety of 2,3-dihydroquinazolin-4(1H)-one derivatives were synthesized using this methodology in good to excellent yields. The catalyst
