group in imidazo[1,2-a]pyridine could increase the radical scavenging activity; On the contrary, the presence of electron-withdrawing might decrease the radical scavenging activity. In addition, cyclopentyl and cyclohexyl groups almost had the same influence on the antioxidant activity. Furthermore, the methoxy moiety had a significant impact on antioxidant capability, and hence syringyl imidazo[1,2-a]pyridines

activities. The most direct way of obtaining this nucleus is the Groebke–Blackburn–Bienaymé three-component reaction (GBB-3CR) between aminopyridines, aldehydes, and isocyanides under both Lewis and Brønsted acid catalysis. However, several catalysts for this reaction have major drawbacks such as being expensive, extremely dangerous, strong oxidizing, and even explosive. In this scenario, heteropolyacids
An efficient and chemoselective C(sp(2))-N bond cleavage of aromatic imidazo[1,2-a]pyridine molecules is developed. A broad scope of amide compounds such as alpha-ketoamides and N-(pyridin-2-yl)arylamides are afforded as the final products in up to quantitative yields. Diverse C-N bond cleavages are controlled by the oxidative species used in this transformation, with various amide products afforded in a chemoselective fashion. A preliminary study indicated that some alpha-ketoamides exhibit anti-Tobacco Mosaic Virus activity for potential use in plant protection.
