An efficient copper(I)-catalyzed direct regioselective arylamination of various heterocyclic N-oxides was achieved successfully under redox-neutral conditions using anthranils as arylaminating reagents. The developed protocol is simple, straightforward, and economic with a broad range substrate scope. dual functional groups in the final molecules were utilized to construct structurally functionally diverse nitrogen-containing organic π-conjugated systems.
