Abstract A preparation of dimethyl 4, 4′-dimethoxy-5, 6, 5′, 6′-dimethylenedioxybiphenyl- 2, 2′-dicarboxylate (VII) was readily achieved. It provided the advantages of specificity, simplicity, and efficiency in reactions. 6-Phenyl-3, 9-dimethoxy-1, 2-methylenedioxy-10, 11- methylenedioxy-6, 7-dihydro-5H-dibenz (c, e) azepin (X) was successfully synthesized from VII (DDB) and its liver-protective property proved to be more effective than DDB and ...
