Abstract
The first one-pot copper-catalyzed highly regioselective C–N bond formation between aryl/alkyl amines and sulfonamide-substituted naphthoquinones was accomplished. Facile chemoselective routes obtained diverse ring-opening 6-amino/anilino-naphthalen-dione-1-sulfonamides and ring-fused 6-amino/aniline-5H-naphth[1,8-cd]isothiazol-5-one,1,1-dioxides with great functional group tolerance. Regiochemistry was confirmed by 1D- and 2D-NMRs.
