Abstract: An unprecedented synthesis of 4-ethenyl quinazolines via a Rh(III)-catalyzed C–H activation and annulation reaction was described. In particular, when C-alkyl imidamides are benzyl groups, 2-benzoyl quinazolines can be obtained. This protocol enables the effective application… read more here.
