<p>The invention at hand describes functionalized diols of diamondoids, in which one of the two hydroxy groups is masked by a protective group, as well as methods for producing these functionalized diols. The protective group is a group —CHR1R2, wherein R1 and R2 stand for alkyl groups and the protective group comprises at least one halogen atom. The monoethers of the diamondoid diols according to the present invention are produced by reacting the diamondoid diol with a halogenated alcohol CHOHR1R2 in the presence of a catalyst acid. The monoetherified diols allow for the targeted production of derivatives of diamondoids, for example, of the corresponding aminoalcohols and aminocarboxylic acids. For that purpose, the diamondoid monoether is reacted in a first step with a halogen nitrile in a Ritter reaction to the corresponding monoether amide. From this monoether amide, the corresponding aminoalcohol can be produced by reacting the protective group —CHR1R2 first with trifluoroacetic acid to the alkanoyloxy group and by subsequently obtaining the aminoalcohol by reaction with thiourea, ethanol and glacial acetic acid. The aminoalcohol can be reacted with a sulfuric acid/formic acid or oleum/formic acid to the corresponding aminocarboxylic acid. The amino, hydroxy and carboxylic groups of the diamondoids can be converted into many other functional groups.</p> |
