Synthesis of diversely functionalized quinoline-2-carboxylates is illustrated through electrochemical cross-dehydrogenative coupling between N-aryl glycinates and methylenecyclopropanes. An extensive range distinct functionalities well-compatible under these transition-metal- oxidant-free mild conditions, contributing to a broad substrate scope practical applicability. Cyclic voltammetric measurements control experiments suggested formal [4 + 2] cycloaddition involving radical intermediates, followed by cyclopropyl ring opening nucleophilic polar addition, consecutively fabricating C–C C–N bonds.
