CYCLOHEXANE-, CYCLOHEXENE- AND CYCLOHEXADIENE, BICYCLOÛ2.2.1¨HEPTANE AND BICYCLO Û2.2.1¨HEPTENECARBOXYLIC ACID ESTERS, AND ALSO PERFUME COMPOSITIONS AND PERFUMED PRODUCTS WHICH CONTAIN ONE OR MORE OF SAID COMPOUNDS AS PERFUME COMPONENT

摘要

Perfume compositions and perfumed products comprising an effective odorant amount of at least one compound having the formula 1 CHEM wherein X and Y each represent a hydrogen atom or X and Y together represent a methylene bridge, R represents an alkyl, alkenyl or cycloalkyl group containing 1-6 carbon atoms, and R1-R4 each represent a hydrogen atom or a methyl group, with the proviso that if X and Y each represent a hydrogen atom, the following cases apply: - if R1 represents a methyl group, R4 represents a methyl group and R2 and R3 represent a hydrogen atom; - if R3 represents a methyl group, R1 and R4 both represent a hydrogen atom; and - if neither R1 nor R3 represents a methyl group, R2 and R4 both represent, or one of the two represents, or neither of the two represents, a methyl group; and if X and Y together represent a methylene bridge, at most one of the symbols R1-R4 represents a methyl group; the double dotted line represents a single or a double bond, in which case - if X and Y and also R1-R3 represent a hydrogen atom and R4 represents a methyl group, the double dotted line together with a single dotted line, or two single dotted lines, may together represent a pair of conjugated double bonds, and - if X and Y and also R1-R3 represent a hydrogen atom, R4 may also represent a methylene group, in which case the double dotted line together with the dotted line directed towards R4 represent a pair of conjugated double bonds, as well as the compounds as such; said compounds are characterized by flowery, fruity, green and spicy odours, sometimes accompanied by a slight minty nuance with animal and/or woody notes in the after-odour.
