A different approach for the synthesis of N-substituted 2-carboxy-4-quinolones using direct reductive amination followed by LiHMDS-induced cyclocondensation has been developed. A range of analogues of the title compounds with broad substrate scope were obtained in moderate yields and good regioselectivity.

An efficient electrochemical approach for the synthesis of 4-quinolones via intramolecularC(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.
