摘　　要：Summary of main observation and conclusion An electrochemical synthesis of oxazol-2-ones and imidazol-2-ones has been developed via 5-exo-dig cyclization of propargylic carbamates-and ureas-derived amidyl radicals.The electrosynthesis relies on the dual function of 2,2,66-tetramethylpiperidin-1-y oxyl(TEMPO)as a redox mediator for amidyl radical formation and an oxygen atom donor.The reactions are conducted under mild conditions using a simple setup and provide convenient access to functionalized oxazol-2-ones and imidazol-2-ones from readily available materials.
