A new methodology for the synthesis of tetrahydroimidazo[1,5-]quinoxalin-4(5)-ones has been accomplished through annulation of quinoxalin-2(1)-ones initiated by electrochemical decarboxylation of -arylglycines catalyzed by ferrocene. With a pair of oxidative and reductive processes occurring among the substrates and intermediates instead of on the electrodes, the electricity consumption was decreased.
