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.
