Abstract: The Amberlite 15 catalyzed synthesis of substituted 2,3-dihydroquinazolin-4(1H)-ones was reported. The reaction conditions were optimized by screening in different solvents and catalysts. The substrate scope of the reaction was also studied, and

A novel multi-component reaction strategy was developed for the construction of important building blocks, 2-amino 3-substituted quinazolinone derivatives from isatoic anhydride and amine with electrophilic cyanating compound, N-cyano-4-methyl-N-phenylbenzenesulfonamide (NCTS). The quinazolinone synthesis proceeds via a sequential series of reactions such as nucleophilic attack of the amine group on the carbonyl group of isatoic anhydride followed ring opening and subsequent decarboxylation, nucleophilic attack of amine to nitrile, followed by heterocyclization.

Some new 4-quinazolinones were prepared. Their antiplatelet activity was evaluated in vitro with respect to aggregation induced by ADP, collagen, arachidonic acid and the platelet serotonin release reaction. Most molecules showed an inhibiting power similar to that of acetylsalicylic acid under the same conditions, and even greater when aggregation was induced by ADP. Reduction of the 4-quinazolinone derivatives to their 1,2,3,4-tetrahydroquinazoline homologues produced an increase in platelet inhibitory action except when ADP is the inductor.
