The versatile synthons 2-chloro-N-(4-sulfamoylphenyl)acetamides la,b were used as a key intermediates for the synthesis of sulfonamide derivatives with adamantyl 2, indene 3, morpholinophenyl 4, pipronyl 5, benzothiazole 6-8, pyrazole 9, thiadiazole 10,11, quinoline 12, isoquinoline 13, thiazoles 14-19, acrylamides 20-24 and benzochromene 25 moieties via reaction with several nitrogen nucleophi...

Arylation of heteroarene has been intensively studied over the past few years because aryl-substituted aromatic heterocycles are known to exhibit interesting biological activities and are also useful as electronic materials. Numerous methods have been reported to successfully construct this motif by transition-metal-catalyzed cross-coupling and most of them required expensive transition-metal c...
