摘要

An efficient and highly regioselective palladium(II)-catalyzed oxidative C-3 alkenylation of imidazo[1,2-a]pyridines with acrylate, acrylonitrile, or vinylarenes has been developed by using oxygen as an oxidant. Substrates such as acrylate and acrylonitrile tended to form beta-product, while vinylarenes tended to form the sole alpha-products.
