Patent ID: 7211680

Claim:
A compound of formula I wherein Y 1 means a hydrogen atom, a hydroxyl group, an alkanoyloxy group with 1 to 12 C atoms or an aroyloxy group, Y 2 means a hydrogen atom or an alkanoyl group with 1 to 12 C atoms or an aroyl group, R 1 and R 2 each mean a hydrogen atom or together an exocyclic methylene group, R 3 and R 4 , independently of one another, mean a hydrogen atom, a chlorine or fluorine atom, an alkyl group with 1 to 4 carbon atoms, or together form a methylene group, or together with quaternary carbon atom 20 form a 3- to 7-membered, saturated or unsaturated carbocyclic ring, Q means a straight-chain or branched carbon unit with up to 10 carbon atoms, which at any position can have hydroxyl groups, in α- or β-position, which in turn can be etherified or esterified, keto groups, amino groups or halogen atoms, R 5 and R 6 together with carbon atom 25 mean a 3- to 7-membered, saturated or unsaturated carbocyclic ring, Z means a five- or six-membered carbocyclic ring which can be saturated, unsaturated or aromatic, and which can be substituted by one or more alkyl chains, which can be straight-chain or branched, saturated or unsaturated, and optionally interrupted by oxa, thia, aza, sulfoxide or sulfo groups or substituted by hydroxy groups or halogen atoms, wherein if Z is phenyl, R 5 and R 6 together with carbon atom 25 form a cyclopropyl, cyclobutyl, cyclopentyl or cyclohexyl ring.
