Divergent Construction of Diverse Scaffolds through Catalyst-Controlled C−H Activation Cascades of Quinazolinones and Cyclopropenones

A transition-metal-catalyzed C-H activation cascade strategy to rapidly construct diverse quinazolinone derivatives in a one-pot manner is reported. The catalysts play an important role in the different transformations. Additionally, the procedure is scalable, proceeds with high efficiency and good chemo-/regio-selectivity, and tolerates a range of functional groups.
