1. Tetrahydrofurane derivatives of the formula I see diagramm : EP0000002,P22,F6 in which R**1 to R**6 are identical or different and represent hydrogen, straight-chain or branched C1-6 alkyl, C1-2 halogenalkyl with up to three identical or different halogen atoms, alkoxyalkyl with 1 or 2 C atoms in each alkyl part, as well as phenyl or benzyloxyalkyl with 1 or 2 C atoms in the alkyl part each optionally substituted by halogen, C1-2 alkyl, C1-2 alkoxy or C1-2 halogenoalkyl with up to three identical or different halogen atoms, R**5 and R**6 together also represent a saturated carboxylic ring with altogether 3 to 6 C atoms, R**7 represents hydrogen, straight-chain or branched C1-6 alkyl, C3-6 cycloalkyl, C2-4 alkenyl, C2-4 alkinyl, alkoxyalkyl with 1 to 2 C atoms in each alkyl part, as well as phenyl or benzyloxyalkyl with 1 or 2 C atoms in the alkyl part each substituted by halogen, C1-2 alkyl, C1-2 alkoxy, or C1-2 halogenoalkyl with up to three identical or different halogen atoms, R**8 and R**9 are identical or different and represent hydrogen, straight-chain or branched C1-6 alkyl, C2-4 alkenyl, C2-4 alkinyl, C3-6 cycloalkyl, C1-4 alkoxy, as well as phenyl, benzyl or benzyloxy each optionally substituted by halogen, C1-2 alkyl, C1-2 alkoxy or C1-2 halogenoalkyl with up to three identical or different halogen atoms, R**10 represents hydrogen, straight-chain or branched C1-6 alkyl, C2-4 alkenyl, C2-4 alkinyl, C1-2 halogenoalkyl with up to three identical or different halogen atoms, as well as phenyl optionally substituted by halogen, C1-2 alkyl, C1-2 alkoxy or C1-2 halogenoalkyl with up to three identical or different halogen atoms and Y represents optionally substituted aryl with 6 to 10 C atoms, which can carry one or more identical or different substituents from the following : the halogens fluorine, chlorine or bromine ; alkyl and alkoxy with in each case 1 to 4 C atoms ; halogenoalkyl, halogenoalkoxy and halogenoalkylthio with in each case up to 4 C atoms and up to 5 halogen atoms ; phenyl, phenoxy or phenoxycarbonyl optionally substituted by halogen, alkyl and alkoxy with in each case 1 to 2 C atoms as well as halogenalkyl with up to 1 C atoms and up to 3 identical or different halogen atoms as well as halogenoalkyl with up to 1 C atoms and up to 3 identical or different halogen the tri-, tetra- or penta-methylene radical ; with the proviso that if Y represents phenyl this must be substituted if R**1 to R**10 denote hydrogen. |
