We report herein a one-pot copper(II)-catalyzed coupling-cyclization leading to small molecules based on a novel structural motif, i.e. the pyrrolo[2,1-f][1,2,4]triazine moiety fused with an isoquinoline ring. The reaction is easy to perform in good to excellent yields with high atom economy and exhibits a broad substrate scope.
