, p. 1377 - 1380 (2004)
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 α-organosulfonyloxy ketones and their subsequent cyclocondensation by 2-aminopyridines in one-pot conditions
Iodobenzene-catalyzed synthesis of imidazo[1,2-a]pyridines from aryl ketones with mCPBA in ionic liquid
Chang, Ya-Li,Wang, Huey-Min,Hou, Rei-Sheu,Kang, Iou-Jiun,Chen, Ling-Ching
, p. 153 - 156 (2010)
Iodobenzene-catalyzed synthesis of imidazo[1,2-a]pyridines from aryl ketones with mCPBA as a cooxidant in ionic liquid is described. The method is simple, rapid and practical, generating Imidazo[1,2-a]pyridines from the aryl ketone without isolation of α-

An inexpensive and commercially available Tf2NH-catalyzed 1,6-conjugate addition of imidazopyridine (IMPY) heterocycles to para-quinone methides (p-QMs) is reported. The present transformation provides a diverse class of C3-functionalized triarylmethanes heterocyclic derivatives of imidazopyridine. These metal-free transformations provided a very broad substrate scope of conjugate addition product with a high yield up to 97% within a short duration.
