Iron(III)-catalyzed chelation assisted remote C–H bond oxygenation of 8-amidoquinolines

Iron catalyzed site selective and chelation assisted C–H functionalization in 8-amidoquinolines is achieved. The remote C5-benzoxylation with benzoyl peroxide produced a variety of potentially bioactive 8-arylcarboxamido-5-benzoyloxy quinoline derivatives. The efficiency of the reaction reflects from the wide substrate scope with electronic differentiation on carboxamide and acyl peroxide in addition to tolerance of halo-substitutions on either of the aryls. The reaction is additive, silver free and proceeds without the exclusion of air or moisture.
