Palladium(<scp>ii</scp>)-catalyzed intermolecular oxidative C-3 alkenylations of imidazo[1,2-a]pyridines by substrate-contolled regioselective C–H functionalization

Abstract

An efficient and highly regioselective palladium(<sc>ii</sc>)-catalyzed oxidative C-3 alkenylation of imidazo[1,2-<italic>a</italic>]pyridines with acrylate, acrylonitrile, or vinylarenes has been developed by using oxygen as an oxidant.
