Transition-metal-catalyzed aminometalation of o-alkynylanilines is a promising pathway for the synthesis C3-functionalized indoles. Herein, we describe Cu(II)-catalyzed site-selective C3-heteroarylation indoles from and quinoline N-oxides. A plausible reaction mechanism involving aminocupration followed by nucleophilic addition Cu(II)-indolyl complexes to N-oxides was proposed. Post-transformations generated C3-heteroarylated demonstrated broad applicability developed method.
