    Abstract: The invention relates to at least dinitroxylated diamantanes, and to methods by which means a high yield and selectivity of substituted diamantanes can be produced. According to the invention, dinitroxylated diamantanes can be 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 can be produced in a targeted manner by reaction with other nucleophiles. The inventive methods for producing at least disubstituted diamantanes consist of the following steps: a) at least dinitroxylation, followed by substitution of all of the nitroxy groups with a nucleophile, or b) at least dinitroxylation, then rearrangement in the presence of a strong acid, all nitroxy groups being replaced by a nucleophile in the event of a successful rearrangement, or c) at least dinitroxylation, followed by a reaction with water (as nucleophile), and rearrangement of the at least dihydroxylated compound in the presence of a strong acid, all hydroxy groups being replaced by another nucleophile in the event of a successful rearrangement.

    Abstract translation: 本发明提供至少双准备dinitroxylated Diamantanes。 它还提供了通过该取代在高产率和选择性diamantanes可以制造方法。 本发明的dinitroxylated Diamantanes可以与亲核试剂为相应的二取代diamantanes反应。 令人惊讶地,我们发现至少两个dinitroxylated或羟化diamantanes在强酸的存在下重排,至少4,9- dinitroxylated或羟基化diamantanes出现。 它可通过与其它亲核试剂特别4,9-取代diamantanes反应来制备。 本发明在此提供了一种用于产生至少二取代diamantanes本发明的下列方法:a)至少dinitroxylation,随后所有硝酰基团的取代与亲核试剂,或b)至少两个dinitroxylation,随后重排在强酸的存在下,经过重排的所有 硝酰基被亲核试剂取代或c)至少dinitroxylation,随后与水反应(如在强酸的存在下,在至少两个多羟基化合物的亲核试剂)的重排中,所有的羟基基团的重排后由另一亲核试剂取代。
