An efficient and generalcarbonylative procedure for the synthesis of 3,4-dihydroquinazolin-2(1H)-one from 1-(halomethyl)-2-nitrobenzenes and aryl/alkyl amines have been explored. In this approach, to avoid of using toxic CO gas, a solid and stable CO precursor, TFBen (benzene-1,3,5-triyl triformate), was utilized. With elemental selenium as the catalyst, a variety of aryl/alkyl amines has been tolerated

Previously we reported the potent anticonvulsant activity of 3-dimethylamino-3,4-dihydro-2(1H)-quinazolinone. In this report, a series of 3-alkyl-3,4-dihydro-2(1H)-quinazolinones was synthesized in three steps from isatoic anhydrides or an anthranilic acid. Structure/activity investigations revealed optimal activity for the 3-isopropyl and 3-cyciohexyl analogs. These compounds were effective against
