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.

A convenient synthetic protocol for the synthesis of imidazo[1,2-a]pyridine has been developed by employing one-pot three-component Ugi reaction by employing aromatic amidine, aromatic aldehyde, and isocyanide using 5 mol % of bromodimethylsulfoniumbromide (BDMS) at room temperature. In addition, they also exhibit interesting fluorescence properties, which may be useful for fluorescent probe. Mild
