- 中文摘要: The title compound 30 was synthesized starting from the endo,syn,endo Diels-Alder adduct 3a of hexahydro-5,6,7,8-tetrachloro-9,9-dimethoxy-5,8-methanonaphthalene-1,4-diol diacetate 6 and 1,2,3,4-tetrachloro-5,5-dimethoxycyclopentadiene (TDCp) in six steps, keyed upon a symmetry-allowed [4+4] photocyclization of decahydro-11,12-dioxo-[1,4;5,8]dimethanoanthracene-9,10-diol diacetate 22. The epimeric monoacetate 26 related to 22 was also synthesized and their thermolysis and photolysis were investigated. Oxidation of diol 30 afforded hexacyclic bridged hemiacetal 31 as a result of transannular reaction. The structure of hemiacetal 31 was analyzed by single-crystal X-ray crystallography.
