摘要：

A facile iodine-mediated unprecedented C-C cleavage by employing CuI has been established towards the synthesis of quinazolin-4(3H)-ones and benzo[4,5]imidazo[1,2-c]quinazolines. This protocol involves peroxide free synthetic approach for the stable C-C bond cleavage followed by oxidative annulation to develop a library of fused N-heterocyclic molecules.
