supporting information; experimental part, p. 1532 - 1535 (2010/06/19)
"Figure Presented" We describe the coupling of primary sulfonamides and various halogenated heterocyclic cores, with an emphasis on 2-heteroaryl halides, via copper catalysis. These studies enabled the synthesis of many new mono-N-heteroaryl sulfonamides.
Chemoselective arylsulfenylation of 2-aminoimidazo[1,2-α]pyridines by phenyliodine(III) bis(trifiuoroacetate) (PIFA)

A series of 2-(trifluoroacetamido)imidazo[1,2-a]pyridines was prepared and treated with phenyliodine(III) bis(trifluoroacetate) (PIFA) in the presence of a variety of thiols leading chemoselectively to the corresponding 3-sulfides. Exposure of these adducts to silica gel in MeOH/CH2Cl2 provides a convenient method for the cleavage of the trifluoroacetamide group.
