Photoinitiated multicomponent cascade reaction of Nheteroarenes with unactivated alkenes and trimethylsilyl azide

• The visible-light-induced multicomponent cascade reaction of N -heteroarenes with unactivated alkenes and TMSN 3 has been accomplished. • Acr + MesClO 4 − was used as the photocatalyst. • The reaction has broad substrate scopes. A series of nitrogen-containing heteroarenes such as quinoxaline-2(1 H )-ones, quinolines, isoquinolines, quinoxaline, and quinazoline, were compatible with the reaction and obtained corresponding products in good yields. A visible-light-mediated multicomponent cascade reaction of heteroarenes with unactivated alkenes and TMSN 3 has been developed. This approach gives a practical solution for the eco-friendly modification of N -heteroarenes with a high functional group tolerance and a broad substrate scope. This efficient, green strategy provides access to functional compounds that contain both a heteroarene skeleton and an organic azide structure.
