Dimethyl aminomalonates were electrochemically oxidized in methanol to afford the corresponding cyclization products through the formation of carbon-carbon bonds. Optimum yields were obtained when NaCN was utilized as the supporting electrolyte at room temperature. Presumably, the electrooxidation involves a two-electron oxidation process.
