Abstract

The present invention relates to compounds of Formula (I), wherein the dotted line represents a carbon-carbon single or double bond and R represents a hydrogen atom or a methyl group; which are useful perfuming ingredients to impart odor notes of the musky-earthy and woody, aromatic-fresh type.

First claim

What is claimed is:

1. A compound having an odor character that includes a woody/ambrette-like note having a characteristic aromatic note and lacking or not possessing any significant, animal notes, the compound being of formula

wherein the dotted line represents a carbon-carbon single or double bond and R represents a hydrogen atom or a methyl group.

2. A compound according to claim 1 , wherein R represents a methyl group.

3. A compound according to claim 1 or 2 , wherein said dotted line represents a carbon-carbon double bond.

4. A compound according to claim 1 , specifically as 5,5,6,7,8,8-hexamethyl-3,4,5,8-tetrahydro-1(2H)-naphthalenone 5,5,6,7,8,8-hexamethyl-3,4,4aα,5,8,8aβ-hexahydro-1(2H)-naphthalenone or 5,5,6,8,8-pentamethyl-3,4,5,8-tetrahydro-1(2H)-naphthalenone.

5. A method to confer, enhance, improve or modify the odor properties of a perfuming composition or of a perfumed article, which method comprises adding to said composition or article an effective amount of at least a compound of formula (I)

wherein the dotted line represents a carbon-carbon single or double bond and R represents a hydrogen atom or a methyl group, wherein the compound has an odor character that includes a woody/ambrette-like note having a characteristic aromatic note and lacking or not possessing any significant, animal notes.

6. The method of claim 5 , wherein R represents a methyl group.

7. The method of claim 5 , wherein said dotted line represents a carbon-carbon double bond.

8. The method of claim 5 , wherein the compound is 5,5,6,7,8,8-hexamethyl-3,4,5,8-tetrahydro-1(2H)-naphthalenone 5,5,6,7,8,8-hexamethyl-3,4,4aα,5,8,8aβ-hexahydro-1 (2H)-naphthalenone or 5,5,6,8,8-pentamethyl-3,4,5,8-tetrahydro-1(2H)-naphthalenone.

9. A perfuming composition comprising
i) at least one compound of formula (I)

wherein the dotted line represents a carbon-carbon single or double bond and R represents a hydrogen atom or a methyl 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.

10. The perfuming composition of claim 9 , wherein R represents a methyl group.

11. The perfuming composition of claim 9 , wherein said dotted line represents a carbon-carbon double bond.

12. The perfuming of claim 9 , wherein the compound is 5,5,6,7,8,8-hexamethyl-3,4,5,8-tetrahydro-1(2H)-naphthalenone, 5,5,6,7,8,8-hexamethyl-3,4,4aα,5,8,8aβ-hexahydro-1(2H)-naphthalenone or 5,5,6,8,8-pentamethyl-3,4,5,8-tetrahydro-1(2H)-naphthalenone.
