| abstract |
Compounds of general formula I as well as their pharmaceutically compatible salts are described, in which R 1 stands for hydrogen, C 1 - to C 6 -alkyl, COR 4 , COOR 4 , COSR 4 or CONHR 5 , in which R 4 is C 1 - to C 6 -alkyl or unsubstituted or substituted aryl and in which R 5 is hydrogen, C 1 - to C 6 -alkyl or unsubstituted or substituted aryl, in which R 2 also stands for hydrogen, C 1 - to C 6 -alkyl or C 1 - to C 6 -acyl, and R 3 stands for a C n F 2n+1 group, in which n=1, 2 or 3, or a CH 2 O(CH 2 ) m C n F 2n+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. |
