    Abstract: The present invention relates to use of at least one compound of formula (I) or stereoisomer thereof wherein R is linear or branched C1-C9 alkyl, linear or branched C2-C9 alkenyl, unsubstituted or C1-C3 alkyl-substituted C4-C8 cycloalkyl or substituted or unsubstituted aryl as aroma ingredient. The at least one compound of formula (I) may be used to impart an aroma impression which is reminiscent of a fruity note, green pear note, apple note, juicy—fruity note, styrax note pineapple note, dusty note, watery note, or a combination of two or more notes to a composition and also to enhance and/or modify the aroma of a composition. The present invention is further directed to a composition comprising at least one compound of formula (I) and (i) at least one aroma chemical different from compound of formula (I) and/or (ii) at least one non-aroma chemical carrier. It is also directed to certain compounds of formula (I) per se and processes of their preparation.

    IPC: C11B9/00

    Abstract: The present invention relates to the use of an ether or an ester of a 1-substituted cycloalkanol or of mixtures of two or more ethers or esters of 1-substituted cycloalkanols or of a stereoisomer thereof or of a mixture of two or more stereoisomers thereof as aroma chemicals; to the use thereof for modifying the scent character of a fragranced composition; to an aroma chemical composition containing an ether or an ester of a 1-substituted cycloalkanol or of mixtures of two or more ethers or esters of 1-substituted cycloalkanols or of a stereoisomer thereof or of a mixture of two or more stereoisomers thereof; and to a method of preparing a fragranced composition or for modifying the scent character of a fragranced composition. The invention further relates to specific ethers or esters of 1-substituted cycloalkanols.

    Abstract: The present invention relates to a process for preparing a macrocyclic diketone compound of the formula (I), which comprises the oxidation of a bicycloolefine compound of the formula (II) with an oxidizing agent, formulae (I) (II) where in formulae (I) and (II) A is (CH2)n with n being an integer from 2 to 12, where two hydrogen atoms may be replaced by C1-C4-alkyl, in particular methyl, or two hydrogen atoms, which are bound to adjacent carbon atoms may be replaced by a fused 5- or 6-membered saturated carbocycle; B is (CH2)m with m being 1 or 2, where 1 or 2 hydrogen atoms may be replaced by C1-C4-alkyl, in particular methyl.
