Abstract

The present invention refers to dihydropyran derivatives, and to a process of making the same. The invention further refers to perfume compositions and fragranced articles comprising them.

First claim

The invention claimed is:

1. A method comprising utilizing a compound of formula (I) in the form of any one of its stereoisomers or a mixture thereof

wherein R is hydrogen or methyl, and
n is 1 or 3;
as a fragrance, the method comprising mixing the compound of formula (I) with a consumer product base, or mixing a fragrance composition comprising the compound of formula (I) with a consumer product base.

2. The method of claim 1 , wherein the compound of formula (I) is selected from the group consisting of 4-methyl-2-(3-phenylpropyl)-3,6-dihydro-2H-pyran, 4,6-dimethyl-2-(3-phenylpropyl)-3,6-dihydro-2H-pyran, 4,5-dimethyl-2-(3-phenylpropyl)-3,6-dihydro-2H-pyran, 2-benzyl-4-methyl-3,6-dihydro-2H-pyran, 2-benzyl-4,6-dimethyl-3,6-dihydro-2H-pyran, 2-benzyl-4,5-dimethyl-3,6-dihydro-2H-pyran, and mixtures thereof.

3. A fragrance composition comprising as odorant a compound of formula (I) as defined in claim 1 or a mixture thereof, and a base material.

4. The fragrance composition according to claim 3 further comprising a compound of formula (II)

wherein R is hydrogen or methyl,
n is 1 or 3, and
one of the dashed lines is a carbon-carbon double bond and the other dashed line is a carbon-carbon single bond.

5. A fragranced article comprising as odorant a compound of formula (I) as defined in claim 1 and a consumer product base.

6. The fragranced article according to claim 5 wherein the consumer product base is selected from fine fragrance, household products, laundry products, body care products, cosmetic and air care products.

7. A compound of formula (I) in the form of any one of its stereoisomers or a mixture thereof

wherein
n is 3, and
R is hydrogen or methyl.

8. A method of improving, enhancing or modifying a consumer product base comprising adding thereto an olfactory acceptable amount of a compound of formula (1), or a mixture thereof

wherein R is hydrogen or methyl, and
n is 1 or 3.

9. The method according to claim 8 , wherein the consumer product base is selected from the group consisting of fine fragrance, household products, laundry products, body care products, cosmetic and air care products.

10. A fragrance composition comprising as odorant a compound of formula (1) as defined in claim 2 and a base material.

11. A fragranced article comprising as odorant a fragrance composition as defined in claim 3 and a consumer product base.

12. The fragranced article according to claim 11 wherein the consumer product base is selected from fine fragrance, household products, laundry products, body care products, cosmetic and air care products.
