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

Abstract

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.
