The present invention relates to a new class of compounds, α-decalones or decalols with a 6,7,8a-trimethyl substitution, and their use in perfumery to confer odor notes of the citrus (e.g. grapefruit) type.
Claims15
-10. (canceled)
A perfuming composition comprising
- i) at least one compound of formula
- wherein the dotted lines represent a single or double bond and at least one of said dotted lines represents a double bond;
- n represents simultaneously 0, in which case the oxygen atom is bound to the cyclanic carbon atom by a double bond, or 1, in which case the oxygen atom is bound to the cyclanic carbon atom by a single bond,
- R1 represents a hydrogen atom or a methyl or ethyl group;
- R2 represents a hydrogen atom or a HCO or MeCO group;
- and
- R3 represents a methyl or ethyl group;
- ii) at least one ingredient selected from the group consisting of a perfumery carrier and a perfumery base;
- and
- iii) optionally at least one perfumery adjuvant.
