Visible-Light-Mediated Late-Stage Sulfonylation of Anilines with Sulfonamides.

A visible-light-mediated late-stage sulfonylation of anilines with sulfonamides under simple reaction conditions is presented. Various primary or secondary sulfonamides including several pharmaceuticals were incorporated successfully via N-S bond activation and C-H bond sulfonylation. The synthetic utility of this strategy is highlighted by the construction of complex anilines bearing diverse bioactive groups.
