The present invention relates to bi-and tricyclic compounds of the general formula (I) (I) wherein the dashed lines independently of each other represent a single or a double bond, X represents a group of the formulae X1 to X3 wherein the asterisk denotes the point of attachment to the rest of the molecule, R1a and R1b, independently of each other, are selected from hydrogen or methyl, or R1a together with R1b form a methylene or ethylene group, R2, R3a, R3b, R4, R5a and R5b, independently of each other, are selected from hydrogen or methyl, R6 is selected from hydrogen, methyl or ethyl, and R7 is methyl or ethyl, to a method of preparing said compounds, to the use of a bi- or tricyclic compounds or of mixtures of two or more bi- and tricyclic compounds or of a stereoisomer thereof or of a mixture of two or more stereoisomers thereof as aroma chemicals; to the use of a bi- or tricyclic compound for modifying the scent character of a fragranced composition; to an aroma chemical composition containing a bi- or tricyclic compound or a mixture of two or more bi- and tricyclic compounds 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, comprising incorporating a bi- or tricyclic compound or a mixture of two or more bi- and tricyclic compounds or of a stereoisomer thereof or of a mixture of two or more stereoisomers thereof into said composition.
本发明涉及一般式(I)的双环和三环化合物,其中破折号独立地表示单键或双键,X表示公式X1至X3的一个基团,其中星号表示连接到分子的位置,R1a和R1b独立地从氢或甲基中选择,或者R1a与R1b一起形成亚甲基或乙烯基,R2、R3a、R3b、R4、R5a和R5b独立地从氢或甲基中选择,R6从氢、甲基或乙基中选择,R7为甲基或乙基,本发明还涉及制备该化合物的方法,将双环或三环化合物或两种或两种以上的双环和三环化合物或其立体异构体或两种或两种以上的立体异构体的混合物用作香料化学品的用途;将双环或三环化合物用于改变香味组合的香气特性的用途;含有双环或三环化合物或两种或两种以上的立体异构体或两种或两种以上的立体异构体的混合物的香料化学组合物的用途;以及将双环或三环化合物或两种或两种以上的双环和三环化合物或其立体异构体或两种或两种以上的立体异构体的混合物并入所述组合物中的制备香料组合物或改变香料组合物的香气特性的方法。
