Aliphatic C-H functionalization at indole 2α-position mediated by acyloxythionium species 1 generated from sulfoxide and acid anhydride has been developed. The combination of sulfoxide and TFAA with O-, N- and C-nucleophiles enabled introduction of various substituents in a one-pot procedure. Especially on utilizing DMSO, the combination provided a practical and efficient method for the synthesis of a wide range of 2α-substituted indoles. The Royal Society of Chemistry 2013.
