We herein report a simple and highly efficient microwave-assisted, copper-catalyzed and ligand-free synthetic method for 2-substituted 4(3H)-quinazolinones as domino reaction. This reaction proceeds via self-condensation of substrate (2-bromo/iodo benzamide) in the presence of a strong base and copper catalyst. The substituted quinazolinones were obtained in one-pot reaction by intramolecular cyclization (condensation) via Ullmann–type intermediate. Both the intermediates and quinazolinones were obtained in good yield and can be further used as building blocks for developing the potential novel drug-like compounds.

Reaction of benzamides and N-substituted benzamides with appropriate o-alkenyl and -alkynyl side-chains and (chlorocarbonyl)phenyl ketene gives transient anhydro-1,3-oxazinium hydroxides which readily undergo intramolecular 1,4-dipolar cycloaddition; loss
