A simple and efficient copper-catalyzed method has been developed for synthesis of bicyclic pyrimidinones containing six-, seven-, eight-membered rings under mild conditions. The protocol uses readily available 2-bromocycloalk-1-enecarboxylic acids, amidines, and guanidines as the starting materials, copper-catalyzed cascade couplings provide the corresponding bicyclic pyrimidinones without addition of any ligand or additive, and the method is of economical and practical advantages.
