Direct aerobic oxidative cross-dehydrogenative coupling of aryl acetaldehydes at C-3 position of imidazoheterocycles via copper catalyzed reaction resulted in the synthesis of dicarbonylated imidazoheterocycles in 55-85% yields. The methodology provides a

An efficient copper-catalyzed oxidative coupling of imidazo[1,2-a]pyridines with methyl ketones to directly generate structurally sophisticated 1,2-dicarbonyl imidazo[1,2-a]pyridine derivatives under oxidative conditions is described. The reaction proceeds in good yields using the environmental friendly molecular oxygen as the oxidant. 18O-Labelling experiments unambiguously established that the oxygen of the dicarbonyl products originated from oxygen rather than from water.
