The carbon tetrabromide mediated oxidative carbon-nitrogen bond formation of 2-aminopyridines or 2-aminopyrimidines with β-keto esters or 1,3-diones, leading to a variety of complex imidazo[1,2-α]pyridines or imidazo[1,2-α]pyrimidines, is reported. The re
Synthesis of imidazo[1,2-a]pyridines by the bis(acetyloxy)(phenyl)- λ3-iodane-Mediated oxidative coupling of 2-aminopyridines with β-keto esters and 1,3-diones

Imidazo[1,2-a]pyridine-3-carboxylates can be prepared directly from 2-aminopyridines and β-keto esters by using bis(acetyloxy)(phenyl)- λ3-iodane as an oxidant and boron trifluoride etherate as a catalyst. The amount of catalyst plays a key rol
Thermal and microwave-assisted rapid syntheses of substituted imidazo[1,2-a]pyridines under solvent- and catalyst-free conditions

experimental part, p. 635 - 641 (2011/04/15)
Thermal and microwave-assisted rapid syntheses of highly substituted imidazo[1,2-a]pyridine derivatives by reaction of aminopyridines and -bromo - keto esters under solvent-free conditions are described. Reactions carried out under microwave irradiation give the highest yields of products in reaction times of less than two minutes. Georg Thieme Verlag Stuttgart New York.
