Copper-Catalyzed Cascade Cycloamination of α-Csp(3)-H Bond of N-Aryl Ketimines with Azides: Access to Quinoxalines.
A copper-catalyzed cycloamination of α-Csp(3)-H bond of N-aryl ketimines with sodium azide has been developed. This methodology provides an efficient access to quinoxalines and features mild reaction conditions and readily available ketimines with diverse functional group tolerance.
