A Rh‐catalyzed unique and direct approach for constructing a series of 5‐arylimidazo[1,2‐c]quinazolines in moderate to excellent yields from simple and readily available 2‐arylimidazoles and 3‐phenyl‐1,4,2‐dioxazol‐5‐ones was described. This procedure proceeds with sequential ortho‐C−H bond amidation and cyclization, which represents a facile and straightforward pathway to access such frameworks.
