The novel use of zincchloride to catalyze the one-pot, three component synthesis of imidazo[1,2-a]pyridines from a range of substrates using either conventional heating or microwave irradiation is described. This methodology affords a number of imidazo[1,2-a]pyridines in reasonable yields and short reaction times without any significant optimization of the reaction conditions.

Rapid Synthesis of 3‐Aminoimidazo[1,2‐<i>a</i>]Pyridines and Pyrazines
Abstract p‐Toluenesulfonic acid catalyzed the one‐pot, three‐component synthesis of 3‐aminoimidazo[1,2‐a]pyridines and pyrazines through a condensation reaction of a 2‐aminoazine, an aldehyde, and an isocyanide at room temperature. This methodology affords a number of 3‐aminoimidazo[1,2‐a]pyridines in reasonable yields and short reaction times without any significant optimization of the reaction conditions
When general and reliable, multicomponent reactions are among the most powerful tools in modern drug discovery. The principle of chemical ligation of reactive partners (see reaction scheme) has been employed to find a new, highly efficient synthesis of fused 3-aminoimidazoles.
