Claim:
A compound formula I, in which Y 1 and Y 2 , independently of one another are, each a hydrogen atom or —C(O)R 5 , Y 3 is a hydrogen atom, hydroxy, a halogen atom, —OC(O)R 5 or —OR 5 , wherein Y 3 can be present in the 2α-situation or the epimeric 2β-situation, R 5 is an aromatic radical with 5 to 12 C atoms or an aliphatic, straight-chain or branched, saturated or unsaturated C 1 –C 12 alkyl radical, which optionally is interrupted by 1–2 oxygen atoms, 1–2 sulfur atoms and/or 1–2 NH groups and/or optionally is substituted by 1–2 hydroxy groups, 1–2 amino groups, 1–2 SH groups, 1–2 COOH groups and/or 1–2 phenyl groups, R 1 and R 2 are each a hydrogen atom or together are an exocyclic methylene group, R 3 and R 4 , independently of one another, are each a hydrogen atom, a fluorine, chlorine or bromine atom, an alkyl group with 1 to 4 carbon atoms, or together are a methylene group or together with quaternary carbon atom 20 a 3- to 7-membered, saturated or unsaturated carbocyclic ring, Q is a straight-chain alkylene group with 1 to 5 carbon atoms, X 1 and X 2 together are a double-bound keto-oxygen atom or, independently of one another, are each a hydrogen atom, a hydroxy group, —O(CO)R 5 , or a fluorine, chlorine or bromine atom, wherein X 1 and X 2 , are not both a hydroxy group or both an —O(CO)R 5 group, Z is an oxazole, thiazole, benzoxazole, or benzothiazole ring, which in each case is unsubstituted or substituted by one or more fluorine, chlorine, bromine or iodine atoms, one or more hydroxy groups, one or more COOR 6 groups, and/or one or more C 1 –C 5 alkyl groups, which in turn can be substituted by one or more fluorine, chlorine, bromine or iodine atoms, C 1 –C 6 alkoxy groups and/or COOR 6 groups, and R 6 is C 1 –C 6 alkyl, benzyl or phenyl, and all possible epimers or diastereomers and mixtures thereof.
