Patent ID: 7109214

Claim:
Substituted cyclopentene compounds of the formula I, in which R 1 denotes an optionally at least mono-substituted phenyl group, which may be condensed with an optionally at least mono-substituted, saturated, unsaturated or aromatic monocyclic ring system optionally comprising at least one heteroatom as a ring member, R 2 denotes a linear or branched alkyl group or an —NH 2 group, R 3 denotes an —NR 4 R 5 group or an —NR 6 R 7 group, R 4 and R 5 , identical or different, in each case denote hydrogen or a linear or branched alkyl group, with the proviso that the two groups R 4 and R 5 do not simultaneously mean hydrogen, R 6 and R 7 , together with the nitrogen atom bridging them as a ring member, form a saturated, optionally at least mono-substituted, heterocyclic optionally comprising at least one further heteroatom as a ring member, A denotes a C(═O) group or a C(H) (R 8 ) group, R 8 denotes an OH group or an —O— (C═O)—R 9 group, R 9 denotes a linear or branched alkyl group, in each case optionally in the form of the pure stereoisomers thereof, enantiomers or diastereomers, the racemates thereof or in the form of mixtures of the stereoisomers, the enantiomers and/or diastereomers, in any desired mixing ratio, or in each case in the form of corresponding salts or in each case in the form of corresponding solvates.
