- 中文摘要:
The title compound (7) was synrhesized in six steps from 1,8,9,10-tetrachloro-11,11-dimethoxy-endo-tricyclo[6.2.1.0/sup 2,7/]undeca-4,9-diene-3,6-dione (4) in an overall yield of 36%. The key intermediate, 1,8,9,10-tetrachloro-11,11-dimethoxy-endo-tricyclo-[6.2.1.0/sup 2,7/]undeca-3,5,9-triene (12), obtained from 4 by reduction, mesylation and then 1,4-elimination, was allowed to react with diethyl azodicarboxylate to afford the Diels-Alder adduct 16. Photochemical closure of 16, followed by hydrolysis and decarboxylation, gave the title compound.
The title compound failed to give either the homopentaprismanone derivative 3 or the diene 9 by the photochemical or thermal elimination of molecular nitrogen. - 英文摘要: --
