Patent ID: 7112584

Claim:
A compound of formula I in which A) R 1 and R 2 together with the C atom of the chain, stand for a ring with a total of 3–4 links, R 3 stands for a hydrogen atom or a C 1 –C 2 -alkyl group, R 4 stands for a hydrogen atom or a C 1 –C 2 -alkyl group, and R 5 to R 8 are the same or different from one another and stand for a hydrogen atom or a halogen atom, or R 4 and R 5 together stand for a 5-membered heterocyclic ring, which in addition to the oxygen atom optionally can contain another oxygen atom or nitrogen atom; B) R 1 and R 2 are the same or different and stand for a C 1 –C 2 -alkyl group, or, together with the C atom of the chain, stand for a ring with a total of 3–4 links, R 3 stands for a hydrogen atom or a C 1 –C 2 -alkyl group, R 6 to R 8 are the same or different from one another and stand for a hydrogen atom or a halogen atom, and R 4 and R 5 together stand far a 5-membered heterocyclic ring, which in addition to the oxygen atom optionally can contain another oxygen atom or nitrogen atom; C) R 1 and R 2 together with the C atom of the chain, stand for a cyclopropyl ring or a cyclobutyl ring, R 3 stands for a hydrogen atom or a methyl group, R 4 stands for a hydrogen atom or a methyl group, and R 5 to R 8 stand for a hydrogen atom and optionally in one or two positions for a fluorine, chlorine, bromine or iodine atom, or R 4 and R 5 together with the inclusion of the phenyl ring atoms 2 and 3 stand for a furan ring, a dihydrofuran ring, a 1,3-dioxole ring or a 1,3-oxazole ring, and R 6 , R 7 and R 8 mean a hydrogen atom and optionally fluorine, chlorine, bromine or iodine atoms in one or two positions, or D) R 1 and R 2 are the same or different and stand for a methyl group or wi ethyl group, or together with the C atom of the chain, stand for a cyclopropyl ring or a cycloburyl ring, R 3 stands for a hydrogen atom or a methyl group, R 4 and R 5 together with the inclusion of the phenyl ring atoms 2 and 3 stand for a furan ring, a dihydrofuran ring, a 1,3-dioxole ring or a 1,3-oxazole ring, and R 6 , R 7 and R 8 mean a hydrogen atom and optionally fluorine, chlorine, bromine or iodine atoms in one or two positions, which compound of formula I can be in its enantiomeric form or its racemic form.
