1. A compound of formula I wherein R1 is a mono- or bicyclic 5- to 10-membered aryl or heteroaryl group, which heteroaryl contains 1 to 4 heteroatoms selected from the group consisting of N, O and S, and which aryl or heteroaryl may optionally be substituted by R9, R10 and/or R11, in which R9 is hydrogen, halogen, cyano, 1-4C-alkyl, 2-4C-alkenyl, 3-6C-cycloalkyl, 1-4C-alkoxy, completely or partially fluorine-substituted 1-4C-alkyl, completely or partially fluorine-substituted 1-4C-alkoxy, pentafluorosulfanyl, cyano-1-4C-alkyl, 1-2C-alkyl-3-6C-cycloalkyl, cyano-3-6C-cycloalkyl, 1-2C-alkoxy-1-4C-alkyl, hydroxy-1-4C-alkyl or 3-(1-2C-alkyl)-oxetan-3-yl, R10 is hydrogen, halogen, cyano, 1-4C-alkyl, 2-4C-alkenyl, 3-6C-cycloalkyl, 1-4C-alkoxy, completely or partially fluorine-substituted 1-4C-alkyl, completely or partially fluorine-substituted 1-4C-alkoxy, cyano-1-4C-alkyl, methyl-3-6C-cycloalkyl, cyano-3-6C-cycloalkyl, methoxy-1-4C-alkyl, hydroxy-1-4C-alkyl or 3-(1-2C-alkyl)-oxetan-3-yl, R11 is hydrogen or halogen, or R9 and R10 together and with inclusion of the carbon atoms, to which they are attached, form a 5-6C-cycloalkane ring wherein one methylene group may optionally be replaced by oxygen,
which ring, for the case of 6-membered ring system, may optionally contain a double bond, and/orwhich ring may optionally be mono- or disubstituted by methyl, wherein, for the case that both methyl groups are connected to the same carbon, the methyl groups together with the carbon to which they are connected, may optionally form a cyclopropyl ring, R2 is 1-6C-alkyl, 1-3C-perfluoroalkyl, 1-4C-alkoxy-1-4C-alkyl, or 4-7C-cycloalkyl, which 4-7C-cycloalkyl may optionally be mono- or disubstituted by fluorine, hydroxy, methoxy and/or 1-2C-alkyl and in which, for the case of 5-7C-cycloalkyl systems, one methylene group may optionally be replaced by oxygen, R3 is hydrogen or 1-4C-alkyl, R4 is hydrogen or 1-4C-alkyl, or R3 and R4 together and with inclusion of the carbon atom, to which they are attached, form a 4-7C-cycloalkane ring, R5 is hydrogen or 1-4C-alkyl, R6 is 1-4C-alkyl, R7 is hydrogen or 1-4C-alkyl,
or R6 and R7 together and with inclusion of the carbon atom, to which they are attached, form a 5-7C-cycloalkane ring wherein one methylene group may optionally be replaced by oxygen,which ring may optionally contain one double bond, and/orwhich ring may optionally be mono- or disubstituted by fluorine, hydroxyl, 1-2C-alkoxy and/or 1-2C-alkyl, R8 is hydrogen, acetoxy, propionyloxy, methoxy or hydroxy, or a tautomer thereof, a stereoisomer thereof, a mixture thereof or a salt thereof. |
