Abstract

A direct and efficient method for the conversion of alkyl aryl ketones to imidazo[1,2-a]pyridines has been developed based on initial formation of a-organosulfonyloxy ketones and their subsequent cyclocondensa- tion by 2-aminopyridines in one-pot conditions. ... Keywords: Hypervalent iodine(III) sulfonate; Cyclocondensation; 2-Aminopyridines. ... Imidazo[1,2-a]pyridines are of interest due to their antiinflammatory,1 potential antirhinoviral,2 long-acting lo- cal ...
