Claims7
A flavor and fragrance formulation comprising at least one compound of formula (I):
- wherein R1 is —OH or —O(CO)CH3.
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 R1 is —OH or —O(CO)CH3.
A compound of formula (Ib):
- wherein AcO represents an acetyloxy group CH3(CO)O—.
A process for the manufacture of a compound of formula (Ib):
- wherein AcO represents an acetyloxy group CH3(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).
