An efficient and chemoselective C(sp2)-N bond cleavage of aromatic imidazo[1,2-a]pyridine molecules is developed. A broad scope of amide compounds such as α-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 α-ketoamides exhibit anti-Tobacco Mosaic Virus activity for potential use in plant protection.

A one-pot catalyst, solvent, work-up and column free synthesis of 3-aminoimidazo-fused heterocycles by a three-component reaction of a 2-aminoheterocycle, aldehyde, and isocyanide is presented. This efficient and green protocol has the advantages of environmental friendliness, high yields and operational simplicity.

A highly efficient and mild protocol for the synthesis of imidazo-fused polyheterocycles via Groebke-Blackburn-Bienaymè reaction under the influence of catalytic amount of lanthanum chloride heptahydrate has been described. A wide range of nitrogen-enriched polyheterocycles are synthesized with high yields under neat conditions.
