    A novel protocol for the synthesis of 2,3-dihydroquinazolin-4(1H)-ones from 2-aminobenzamides and aldehyde derivatives catalyzed by KOH/DMSO suspension has been developed. The present transition metal free methodology is operationally simple, scalable and varieties of 2,3-dihydroquinazolin-4(1H)-one derivatives were obtained in good to excellent yields in short reaction times.

    2,3-Dihydroquinazolin-4(1H)-one derivatives have been synthesized via one-pot reaction of isatoic anhydride, aromatic aldehyde, and ammonium acetate catalyzed by FeCl3/neutral Al2O3 in tert-butanol under reflux conditions. Inexpensive and easily available reagents, convenient work-up procedure, reusable catalyst, and moderate to good yield are the salient features of this protocol.

    An efficient synthesis of (±)‐2‐monosubstituted and (±)‐2,2‐disubstituted 2,3‐dihydro‐4(1H)‐quinazolinones has been developed using a dissolving metal reduction‐condensative cyclization strategy. Treatment of 2‐nitrobenzamide and an aldehyde or ketone with iron powder in refluxing acetic acid affords high yields of the title compounds. More complex ring systems are available by incorporating additional
