An environmentally-benign electrochemical approach for the construction of quinoline derivatives employing N,N-dimethylformamide (DMF) as the methine source has been devised by cyclization of 4-(phenylamino)-2H-chromen-2-ones. In a user-friendly undivided cell, 6H-chromeno[4,3-b]quinolin-6-ones were obtained under chemical oxidant-free and transition-metal-free conditions in 43–92% yields with high functional tolerance. (Figure presented.).
