Copper-Catalyzed Direct, Regioselective Arylamination of N-Oxides: Studies To Access Conjugated pi-Systems

摘要

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. The dual functional groups in the final molecules were utilized to construct structurally and functionally diverse nitrogen-containing organic x-conjugated systems.
