n-Bu4NI-catalyzed selective dual amination of sp3 C-H bonds: oxidative domino synthesis of imidazo[1,5-c]quinazolines on a gram-scale

An n-Bu4NI catalyzed domino reaction that involves selective dual amination of sp(3) C-H bonds has been developed. The protocol affords a facile and efficient approach to the synthesis of imidazo[1,5-c]quinazolines under mild conditions.
