• Ketenimines
• Tandem reaction
• Sulfonyl azide
• Terminal alkynes
• Isatoic anhydride

The one-pot synthesis of a novel class of N-(4-hydroxyquinolin-2-yl)sulfonamide derivatives is achieved in moderate to good yields by the sequential copper-catalyzed reaction between sulfonyl azides, terminal alkynes, and isatoic anhydride in N,N-dimethylformamide.
