The synthesis of quinazolinone derivatives was achieved from 2-iodobenzamide derivatives and various benzylamines, allylamine, and cinnamylamine derivatives through a one-pot copper-catalyzed reaction. In this reaction, the amine component (benzylamine/allylamine/cinnamylamine) is N-arylated with 2-iodobenzamide derivatives through Ullman coupling, followed by an intramolecular C-H amidation in the presence of copper catalyst. Copper-catalyzed tandem-Ullman N-alkylation and intramolecular C-H amidation reaction protocol for the synthesis of 2-phenylquinazolinone and quinazolinone derivatives from N-substituted 2-iodo-benzamides and benzylamines, allyl, and cinnamylamine is achieved.

Condensation of different schiff bases (II) with 2-methyl-4H-3,1-benzoxazin-4-one (I) yields 3-substituted 2-styryl-4(3H)-quinazolinones (III) in good yields.A plausible mechanism for the reaction has been suggested.
