Popis: 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.
