Abstract Aminodesoxy-1.4;3.6-dianhydrohexitol derivatives of the general formula I, (I) Image wherein R1 and R2, in each case independently of one another, signifies a hydrogen atom or a lower alkyl- group with 1 to 4 C-atoms or wherein R1 signifies a hydrogen atom and R2 an adamant(1)yl radical or wherein R1 and R2, together with the nitrogen atom to which they are attached, (a) signify the residue of a cyclic, non- aromatic secondary amine possibly containing a further hetero atom or (b) the aden(9)yl radical possibly mono- or disubstituted on the 6-amino group or (c) the 6- alkylmercaptopurin(9)yl radical or (d) the theophyllin- (7)yl radical or (e) the 6-chloropurin-9-yl radical or wherein R1 signifies a hydrogen atom or a lower alkyl group with 1 to 4 C-atoms and R2 an .omega.-theophyllin(7)yl- alkyl radical or an .omega.-theobromin-1-ylalkyl radical or an .omega.-(N,N'-di-lower alkyl-substituted xanthin-N''-yl)- alkyl radical, whereby "lower alkyl" signifies an alkyl group with 1 to 5 C-atoms, or an .omega.-adenin-9-ylalkyl radical, whereby the alkyl radical has 2 to 7 C-atoms - 2 - and can be straight-chained or branched, and wherein R3 signifies a hydrogen atom, a methanesulphonyl or toluenesulphonyl group, as well as their acid-addition salts. Processes for the preparation of said compounds and use of said compounds as reactive intermediate products for the preparation of the corresponding pharmacologically-effective amino-desoxy-1.4;3.6-dianhydro- hexitol nitrates.
