The present invention relates to the use of a compound of the general formula (I) wherein R1 is C1-C4-alkyl or -(C=0)-R3, R2 is hydrogen, C1-C4-alkyl or -(C=0)-R4, and R3 and R4, independently of one another, are selected from the group consisting of hydrogen and C1-C4-alkyl, a stereoisomer thereof or a mixture of stereoisomers thereof, as an aroma chemical, to aroma chemical compositions comprising at least one compound of the general formula (I), a stereoisomer thereof or a mixture of stereoisomers thereof, and to a method for preparing a fragranced ready-to-use composition, which comprises incorporating at least one compound of the general formula (I), a stereoisomer thereof or a mixture of stereoisomers thereof, into a ready- to-use composition. The present invention further relates to specific ethers and specific esters of the compounds of the general formula (I) and a method for their preparation.
The invention relates to mixtures having:
components (a) having at least one fragrance of the formula (I)
where
R1=OC-R2, CH

OR3, C1-C8 open-chain or branched aliphatic radical, optionally substituted and/or unsaturated,
with R2=an open-chain or branched aliphatic radical, optionally substituted and/or unsaturated, having 2-10 C atoms,
with R3=an open-chain or branched aliphatic radical, optionally substituted and/or unsaturated, having 1-8 C atoms, and
components (b) having at least one fragrance, different from the fragrances of component a,
characterized in that the weight ratio of all components (a) to all components (b) is from 1:10 to 1:10000.
