Abstract

An efficient electrochemical approach for the synthesis of 4-quinolones via intramolecular C(sp3)–H/C(sp3)–H cross-coupling has been developed under metal- and external oxidant-free conditions. This electrochemical approach provides a simple and efficient route to construct useful 4-quinolone derivatives in moderate to good yields.
