Iodine‐Mediated Oxidative Annulation by C–C Cleavage: A Domino Synthetic Approach to Quinazolinones and Benzo[4,5]imidazo[1,2‐c]quinazolines.

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. [ABSTRACT FROM AUTHOR]
