Recent Advances in the Electrochemical Functionalization of Imidazoheterocycles

Imidazoheterocycles have extensive applications in the pharmaceutical industry and agrochemicals. A comprehensive overview has been provided on the current advancements in electrochemical functionalization, which has been classified ten different types of reactions. Electrochemical synthesis has emerged as a highly effective method for producing organic molecules, especially in the context of sustainable development. Employing electrons as the traceless oxidant, several C–H functionalization reactions of imidazo-fused heterocycles have been achieved at either the C3 or C5 positions. Electrons may serve as the reducing agent to synthesize pyridine rings that are either partially or fully saturated in imidazo[1,2-a]pyridines. The purpose of the review is to attract the interest of the scientific community and promote additional research on the functionalization of imidazoheterocycles using electrochemical methods.
