Abstract

in the form of any one of its stereoisomers or a mixture thereof, and wherein each R1, independently from each other, represents a hydrogen atom or a methyl group; R2 and R3 represent, independently from each other, a C1-2 linear alkyl group or a C3-5 linear or branched alkyl group; R2 and R3, when taken together, represent a C2-5 linear, branched alkanediyl and one dotted line represents a carbon-carbon single bond and the second one a carbon-carbon double bond. Also described herein are methods of using compounds of formula (I) as a perfuming ingredient of the floral type and as part of a perfuming composition or of a perfumed consumer product.

First claim

1 . A compound of formula

in the form of any one of its stereoisomers or a mixture thereof, and wherein each R 1 , independently from each other, represents a hydrogen atom or a methyl group; R 2 and R 3 represent, independently from each other, a C 1-2 linear alkyl group or a C 3-5 linear or branched alkyl group; or R 2 and R 3 , when taken together, represent a C 2-5 linear, branched alkanediyl group and one dotted line represents a carbon-carbon single bond and the second one a carbon-carbon double bond.

2 . The compound according to claim 1 , characterized in that the compound is of formula

in the form of any one of its stereoisomers or a mixture thereof and wherein R 1 , R 2 and R 3 have the same meaning as defined in claim 1 .

3 . The compound according claim 1 , characterized in that one R 1 is a hydrogen atom and the other two R 1 may each independently be a hydrogen atom or a methyl group.

4 . The compound according to claim 1 , characterized in that R 1 is a hydrogen atom.

5 . The compound according to claim 1 , characterized in that R 2 is a methyl, an ethyl or an isopropyl group.

6 . The compound according to claim 1 , characterized in that R 3 is a methyl, an ethyl or a propyl group.

7 . The compound according to claim 1 , characterized in that R 2 and R 3 , when taken together, is a C 3 linear alkanediyl group or a C 4 branched alkanediyl group.

8 . The compound according to claim 1 , characterized in that the compound of formula (I) is 3-(4-ethyl-4-methyl-1-cyclohexen-1-yl)propanal, 3-spiro[4.5]dec-7-en-8-ylpropanal, 3-(spiro[5.5]undec-2-en-3-yl)propanal or 3-(4,4-diethylcyclohex-1-en-1-yl)propanal.

9 . A method to confer, enhance, improve or modify the odor properties of a perfuming composition or of a perfumed article, wherein the method comprises adding to said perfuming composition or perfumed article an effective amount of at least a compound of formula (I) as defined in claim 1 .

10 . A method of using the compound of formula (I) as defined in claim 1 , the method comprising using the compound of formula (I) as a perfuming ingredient.

11 . A perfuming composition comprising
i) at least one compound of formula (I), as defined in claim 1 ; 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.

12 . A perfumed consumer product comprising at least one compound of formula (I), as defined in claim 1 .

13 . The perfumed consumer product according to claim 12 , characterized in that the product is a perfume, a fabric care product, a body-care product, a cosmetic preparation, a skin-care product, an air care product or a home care product.

14 . The perfumed consumer product according to claim 13 , characterized in that the perfumed consumer product is a fine perfume, a splash or eau de perfume, a cologne, shave or after-shave lotion, a liquid or solid detergent, a fabric softener, a fabric refresher, an ironing water, a paper, a bleach, a carpet cleaner, a curtaincare product, a shampoo, a coloring preparation, a color care product, a hair shaping product, a dental care product, a disinfectant, an intimate care product, a hair spray, a vanishing cream, a deodorant or antiperspirant, a hair remover, a tanning or sun product, a nail product, a skin cleansing, a makeup, a perfumed soap, shower or bath mousse, oil or gel, or a foot/hand care products, a hygiene product, an air freshener, a “ready to use” powdered air freshener, a mold remover, a furnisher care, a wipe, a dish detergent or hard-surface detergent, a leather care product or a car care product.
