Abstract

An efficient rhodium- and copper-co-catalyzed C-H bond activation and [4 + 2] annulation enables the construction of bioactively important quinazolines. This aerobic oxidative protocol provides a useful application of simple azides in N-heterocycle synthesis with N2 and H2O as byproducts.
