A concise and efficient synthesis of benzimidazo[1,2-c]quinazolines through CuI-catalyzed intramolecular N-arylations

摘要

A series of functionalized benzimidazo[1,2- c ]quinazoline derivatives was obtained in excellent yields under mild conditions through a CuI-catalyzed Ullmann N -arylation starting from easily available starting materials.
