discussed. For this purpose, dimethyl 7-oxa-bicyclo[2.2.1]hepta-2,5-diene-2,3-dicarboxylate was prepared by the addition reaction of furan to dimethyl acetylene dicarboxylate. Fragmentation reaction of dimethyl 7-oxa-bicyclo[2.2.1]hepta-2,5-diene-2,3-dicarboxylate was examined by two different methods; KMnO4/CuSO4·5H2O and OsO4/NaIO4/2,6-lutidine. Ester groups of dimethyl 2-formylfuran-3,4-dicarboxylate
