Abstract
Compounds of general formula I as well as their pharmaceutically compatible salts are described, in which R1 stands for hydrogen, C1- to C6-alkyl, COR4, COOR4, COSR4 or CONHR5, in which R4 is C1- to C6-alkyl or unsubstituted or substituted aryl and in which R5 is hydrogen, C1- to C6-alkyl or unsubstituted or substituted aryl, in which R2 also stands for hydrogen, C1- to C6-alkyl or C1- to C6-acyl, and R3 stands for a CnF2n+1 group, in which n=1, 2 or 3, or a CH2O(CH2)mCnF2n+1 group, in which m=0 or 1 and n=1, 2 or 3. In addition, a process for the production of the compounds with general formula I is indicated. The compounds can be used for the production of pharmaceutical agents.
