Glue! A green and practical one‐pot method for the electrochemical three‐component synthesis of tetrahydroimidazo[1,5‐a]quinoxalin‐4(5H)‐ones using cheap and environmentally benign paraformaldehyde as a C1 synthon, was developed. In this strategy, EtOH played dual roles (eco‐friendly solvent and waste‐free pre‐catalyst) and the in situ generated ethoxide promoted triple sequential deprotonations. Abstract A green and practical method for the electrochemical synthesis of tetrahydroimidazo[1,5‐a]quinoxalin‐4(5H)‐ones through the three...
