New 7-substituted fluoro-2β-acetyl-2α,4α,5,12-tetrahydroxy-1,2,3,4-tetrahydro-6,11-naphthacenediones having the general formula I:
where X is a hydrogen atom, or a hydroxyl group, R and R₁, which cannot be equal, are a hydrogen atom or a fluorine atom; R₂ can be hydrogen atom or a hydroxyl group or an alkoxy group. These fluoro-naphthacenediones can be useful for obtaining new derivatives which show a different reactivity of the 2α hydroxyl, in particular new anthracyclines.
具有通式 I 的新的 7-取代氟-2β-乙酰基-2α,4α,5,12-四羟基-1,2,3,4-四氢-6,11-萘二酮:
其中 X 是氢原子或羟基,R 和 R₁ 不能相等,它们是氢原子或氟原子;R₂ 可以是氢原子或羟基或烷氧基。这些氟萘二酮类化合物有助于获得 2α 羟基具有不同反应活性的新衍生物,特别是新的蒽环类化合物。
