The present invention provides compounds of formula I
wherein
R1 and R3 are independently H or C1-3 alkyl, and R2 is H, C1-3 alkyl, methylene or ethylidene, with the proviso that R1 and R2 are not simultaneously H;
n is 0 or 1; and
- - - is a single or a double bond, wherein a maximum of two double bonds are present in the compound. Compounds of formula II are also provided:
wherein
A is selected from the group of CR4R5OH, CR4R5OC(O)R6, CO2R6, CN and C(O)R4;
R1, R3, R4, and R5 are independently H or C1-3-alkyl;
R2 is H, C1-3-alkyl, methylene, or ethylidene;
R6 is H, C1-3 alkyl, C2-4 alkenyl, or alkinyl;
n is 0 or 1; and
- - - is a single or a double bond, wherein a maximum of two double bonds are present. Compositions containing compounds of formulae I and II, as well as methods for imparting fragrance to substrates using such compounds are also provided.
本发明提供了化合物的公式I,其中R1和R3分别是H或C1-3烷基,R2是H、C1-3烷基、亚甲基或乙基亚甲基,但R1和R2不能同时是H;n为0或1;- - - 是单键或双键,化合物中最多存在两个双键。还提供了公式II的化合物:其中A选自CR4R5OH、CR4R5OC(O)R6、CO2R6、CN和C(O)R4;R1、R3、R4和R5分别是H或C1-3-烷基;R2是H、C1-3-烷基、亚甲基或乙基亚甲基;R6是H、C1-3烷基、C2-4烯烃基或炔烃基;n为0或1;- - - 是单键或双键,化合物中最多存在两个双键。还提供了含有公式I和II的化合物的组合物,以及使用这些化合物为基质赋予香味的方法。
