An innovative procedure for the synthesis of imidazole-based oligomers is presented. The multicomponent, one-pot reaction combines two different imines and an acyl chloride in the presence of carbon monoxide and a palladium catalyst. The reaction proceeds under mild conditions and affords moderate to good yields of the target compounds.
