    • The invention at hand provides at least dinitroxylated diamantanes. In addition, it provides methods for producing substituted diamantanes with high yields and selectivity.According to the invention, dinitroxylated diamantanes are suitable for being reacted with nucleophiles to form the corresponding disubstituted diamantanes. Surprisingly, it was discovered that at least dinitroxylated or hydroxylated diamantanes are rearranged in the presence of a strong acid, creating at least 4,9-nitroxylated or hydroxylated diamantanes. On the basis of this, 4,9-substituted diamantanes are able to be produced in a targeted manner by reaction with further nucleophiles.Thus, the invention at hand provides the following methods according to the present invention for producing at least disubstituted diamantanes: a) at least dinitroxylation, followed by the substitution of all nitroxy groups by a nucleophile or b) at least dinitroxylation, subsequent rearrangement in the presence of a strong acid, after realised rearrangement all nitroxy groups are replaced by a nucleophile or c) at least dinitroxylation, subsequent reaction with water (as nucleophile), rearrangement of the at least dihydroxylated compound in the presence of a strong acid, after realised rearrangement all hydroxy groups are replaced by another nucleophile.
    • 本发明至少提供二硝基甲酰化的二金刚烷。 此外,它提供了以高产率和选择性生产取代的二金刚烷的方法。 根据本发明,二硝基氧化的二金刚烷适于与亲核试剂反应以形成相应的二取代的二金刚烷。 令人惊奇的是,发现在强酸存在下重新排列了二硝基氧化或羟基化的二金刚烷,产生了至少4,9-氨基氧化或羟基化的金刚烷。 基于此,4,9-取代的二金刚烷可以通过与另外的亲核试剂反应而以目标方式制备。 因此,本发明提供了根据本发明的用于生产至少二取代的二金刚烷的以下方法:a)至少二硝基甲酰化,然后用亲核试剂取代所有硝基,或b)至少二硝基甲酰化,随后在 强酸的存在,在实现重排之后,所有的硝基都被亲核试剂取代,或c)至少二硝基甲酰化,随后与水(作为亲核试剂)反应,在强酸存在下重排至少二羟基化的化合物, 重排所有羟基被另一个亲核试剂取代。
