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.
