  3-Acyl imidazo[l,2-a]pyridines with no substituent at position 2 were obtained in moderate to good yields in an improved version of the Tisler protocol for the synthesis of imidazo[l,2-x]azines. It was found that yields are significantly improved if the reaction is carried out in the presence of DMF or in some cases in the absence of a solvent.

  A convenient one-pot, three-component reaction has been developed for the synthesis of 3-aroylimidazo[1,2-a]-N-heterocycles from aryl ketones and 2-amino-N-heterocycles using dimethyl sulfoxide as a methylene donor. The reaction proceeds smoothly catalyzed by I2 in the presence of K2S2O8 and affords the desired products in moderate to good yields. This protocol offers significant superiority in accessing

  An efficient and “green” protocol for the synthesis of 3-acylimidazo[1,2-a]pyridines through intramolecular oxidative α-amination of carbonyl compounds has been developed. The reaction proceeds smoothly utilizing I2 as a catalyst and H2O2 as an oxidant under neat condition with broad substrate scope. Several complex nitrogen-containing fused rings are conveniently constructed, which are not easy to
