A one-pot synthesis, initiated by a copper salt with inorganic (NH4)2CO3 as the nitrogen source, forms divergent aryl imidazole derivatives from ketones via α-amination and oxidative C–C bond cleavage reactions. The approach provides a simple and rapid synthesis of imidazole derivatives and has certain versatility.

A simple and efficient protocol for the synthesis of highlysubstituted imidazoles is developed through the condensation of 1,2-dicarbonyl compound, aldehyde, and ammonium acetate or amine via multi-component condensation strategy. The present method gives good to excellent yields of substituted imidazoles.
