Herein, we report a sustainable route for the synthesis of 1,2,3,4-cyclohexanetetracarboxylate from sugar-derived muconic acid and fumaric acid. The key Diels-Alder reaction constructed a cyclohexene framework substituted by four ester groups. The isolated yield of tetramethyl 5-cyclohexene-1,2,3,4-tetracarboxylate was up to 95.5percent without any catalyst used. And the hydrogenation reaction of the cycloadduct was catalyzed by commercial RANEY? Ni at room temperature and nearly 100percent yield of the cyclohexyl target products was obtained. This journal is
