A strategy for the synthesis of quinazolinones via acceptorless coupling of o-aminobenzamides with methanol has been accomplished in the presence of the metal-ligand bifunctional catalyst Cp*Ir(2,2'-bpyO)(H2O). Notably, this research exhibited the potential of transition-metal-catalyzed activation of methanol as a C1 source for the construction of heterocycles.
