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.

A photocatalytic method for the ring-closing 1,7-enyne metathesis using α-amino radical as an alkene deconstruction auxiliary is present. Preliminary mechanistic studies suggest that intramolecular 1,5-hydrogen atom transfer key to generation and β-scission of radical, while dearomatization arenes ring opening cyclopropanes are construct spirocyclic quinolin-2-ones. This approach highlights potential metathesis, providing a green, efficient, step-economical way synthesis
