A series of 2,3-dihydroquinazolin-4(1H)-ones have been synthesized in good to excellent yields through direct cyclocondensation of anthranilamide and aryl aldehydes or ketones in water or methanol under mild conditi...
A simple and facile method for the synthesis of 2,3-dihydroquinazolin-4(1H)-ones through the direct cyclocon- densation of one-pot three-component cyclocondensation of isatoic anhydride, ammonium acetate (or primar...
2-Substituted-2,3-dihydro-4(1H)-quinazolinones were synthesized in high yield by condensation of 2-anthranilamide with aromatic aldehydes or ketones in refluxing water without catalyst.This protocol has advantages o...
