A stereoselective strategy for the rapid acquisition of the complete framework (dideoxyottelione A) of the promising cytotoxic agent ottelione A, with four contiguous stereogenic centres on a hydrindane skeleton and a sensitive 4-methylenecyclohex-2-enone functionality, from the readily available Diels–Alder adduct of 1,2,3,4-tetrachloro-5,5-dimethoxycyclopentadiene and norbornadiene, is delineated.
描述了一种立体选择性的策略,用于快速获取有前景的细胞毒性药物ottelione A的完整框架(dideoxyottelione A),该框架在氢环烷骨架上具有四个相邻的立体中心,以及一个敏感的4-亚甲基环己-2-烯酮官能团,来源于易得的1,2,3,4-四氯-5,5-二甲氧基环戊二烯和双环戊二烯的Diels–Alder加成物。
