An efficient method for the synthesis of N-(quinolin-2-yl)sulfonamides is described. The intermolecular amidation of quinoline N-oxides with sulfonamides proceeded smoothly in the presence of PhI(OAc)2 and PPh3 to afford N-(quinolin-

The copper-catalyzed ketenimine formation reaction of 1-(o-acetamidophenyl) propargyl alcohols with various sulfonyl azides is found to undergo a concomitant intramolecular nucleophile attack to generate 1,2-dihydro-2- iminoquinolines after aromatization (via elimination of acetyl and hydroxy groups) and tautomerization. The reaction produces 4-substituted and 3,4-unsubstituted title compounds in moderate to good yields under mild reaction conditions.
