Abstract

The present invention relates to the use of specific organic compounds of formula (I) as flavor and fragrance material. Furthermore the invention relates to a new specific organic compound, as well as to flavor and fragrance formulations comprising at least one of the specific organic compounds.

First claim

The invention claimed is:

1. A flavor and fragrance formulation comprising at least one compound of formula (I):

wherein R 1 is —OH or —O(CO)CH 3 .

2. The flavor and fragrance formulation according to claim 1 comprising 0.0001-10 wt-%, relative to the total weight of the flavor and fragrance formulation, of at least one compound of formula (I).

3. The flavor and fragrance formulation according to claim 1 , wherein the flavor and fragrance formulation is solid, gel-like or liquid.

4. The flavor and fragrance formulation according to claim 1 , wherein the flavor and fragrance formulation is a perfume, hair care product, household product, laundry product, body care product or cosmetic product.

5. A method of improving, enhancing or modifying a flavor and fragrance formulation which comprises adding to the flavor or fragrance formulation an olfactory acceptable amount of at least one compound of formula (I):

wherein R 1 is —OH or —O(CO)CH 3 .

6. A compound of formula (Ib):

wherein AcO represents an acetyloxy group CH 3 (CO)O—.

7. A process for the manufacture of a compound of formula (Ib):

wherein AcO represents an acetyloxy group CH 3 (CO)O—, the process comprising the steps of:
i) ethinylating 5,6-dimethyl-5-hepten-2-on to 3,6,7-trimethyl-6-octen-1-in-3-ol;
ii) acylating 3,6,7-trimethyl-6-octen-1-in-3-ol to 3,6,7-trimethyl-6-octen-1-in-3-yl acetate; and
iii) hydrogenating the C≡C triple bond of 3,6,7-trimethyl-6-octen-1-in-3-yl acetate to the saturated C—C bond in the presence of a Lindlar catalyst leading to the compound of formula (Ib).
