by nature, organic chemists have been using a divergent strategy to improve the synthetic efficiency of diverse molecules. Transition-metal-catalyzed C–H functionalization has become one of the most straightforward, powerful, and atom-economical methods to construct complex scaffolds. However, C–H activation initiated divergent transformation to prepare diverse molecules is still limited. To address

An efficient CoIII‐catalyzed cyclization of 2‐arylquinazolinones with alkynes for the synthesis of fused quinazolinones was developed. This method provides a great opportunity for the preparation of a library of quinazolinone based tetracyclic molecules.
