Paragraph 0037; 0038, (2016/10/08)
The invention discloses a preparing method for a C-3 position sulfoimidazo[1,2-a] pyridine compound. The preparing method includes the step that an imidazo[1,2-a] pyridine compound and a sulfohydrazide compound serving as raw materials, tert-butyl hydroperoxide serving as an oxidizing agent, acetonitrile serving as solvent, and an iodine compound serving as a catalyst react at the reaction temperature of 60 DEG C-120 DEG C to obtain the C-3 position sulfoimidazo[1,2-a] pyridine compound. Compared with a traditional synthetic method, the preparing method has the advantages that reaction conditions are moderate, environment pollution is little, reaction smells are small, the yield is high, functional group compatibility is high, and separation and purification are convenient.

A highly efficient and environmentally friendly method for catalytic chalcogenylation of imidazopyridines, imidazopyrimidines, indoles, and pyrrolo[2,3-b]pyridines with dichalcogenides has been developed by using CuI as catalyst under air. The reactions proceed smoothly to give the desired products in moderate to excellent yields, without the presence of other additive.
