Publication number: 20110124912Abstract: 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.Type: ApplicationFiled: June 2, 2009Publication date: May 26, 2011Applicant: JUSTUS-LIEBIG-UNIVERSITAT GIESSENInventors: Peter R.
