n-Bu4NI-catalyzed selective dual amination of sp3 C–H bonds: oxidative domino synthesis of imidazo[1,5-c]quinazolines on a gram-scale†
Abstract
An n-Bu4NI catalyzed domino reaction that involves selective dual amination of sp3 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.
