Copper-Promoted Double Oxidative C–H Amination Cascade for the Synthesis of Imidazo[1,5-a]quinolines

A copper-promoted cascade reaction of 2-methylazaarenes and benzylamines has been developed via sequential double oxidative C(sp(3))-H aminations. This protocol provides straightforward access to imidazo[1,5-a]quinoline derivatives without employing prefunctionalized substrates.
