The Swernoxidation of various indolic substrates is described, and a range of products resulting from overalloxidation at the 2-position were observed. In particular, depending on the substrate and reaction conditions, it was possible to achieve direct oxidation to α,β-unsaturated systems at the 2-position, to introduce a nucleophile at the 2-position, and to introduce a CH3-S-CH2 group at the indole

An oxidative sequence for the conversion of oxindoles to structurally distinct heterocyclic scaffolds and aniline derivatives is disclosed by the combination of a copper-catalyzed C–H peroxidation and subsequent base-mediated fragmentation reaction. In contrast to classic enzymatic (i.e., kynurenine pathway) and biomimetic methods (i.e., Witkop–Winterfeldt oxidation) for oxidative indole cleavage,
