Definitions

• the present invention relates to the field of perfumery. It relates, more particularly, to esters derived from 1-(3,3-dimethyl-1-cyclohexyl)-1-ethanol which have remarkable odor properties.
• esters according to the present invention show useful and prized odor properties and that, as a result, they can be used for the preparation of perfumes, perfuming compositions and perfumed articles. They are employed in order to confer musky type odor effects.
• esters according to the present invention are products which fulfil the requirements for perfuming compounds, and they are capable of replacing the above-mentioned known compounds.
• R is an alkyl group from C 1 to C 3 , and which show an odor of the musky type characterized by an intense note of the type ambrette seeds, fruity-pear, reminiscent of the odor of Williams pears.
• n is an integer from 1 to 3
• the symbols R 6 and R 7 represent each a hydrogen atom or a methyl or ethyl group
• R 5 represents an alkyl or alkoxy group from C 1 to C 4 , linear or branched, an alkenyl group from C 2 to C 4 , linear or branched, or a group of formula
• X is an oxygen atom or an unsubstituted methylene or ethylene group and R 5 is a group as defined in formula (I) and having 1 to 3 carbon atoms.
• esters of the above formulae (I) and (III) are novel compounds.
• the compounds of the invention show musky odor notes in which a slight fruity-ambrette connotation is found, which however is clearly less pronounced than in the compounds of the prior art, namely those according to formula (II).
• the global olfactive impression of the compounds of the present invention is generally that of musky odor compounds having a sweet and heavy connotation, close to that of the so-called polycyclic musks, quite unlike that of the compounds of formula (II) which show lighter and less tenacious olfactive notes.
• the compounds of the invention can be present in the form of 4 stereoisomers in the pure state or as a mixture of the stereoisomers.
• the invention thus includes all these possible mixtures and all the possible individual isomers.
• the odor of every possible isomer mixture can also change as a function of the content of any given diastereomer or enantiomer.
• this compound of the invention develops a musky odor which is distinctly more tenacious and heavier than those of known compounds, which makes it particularly useful for the creation of base notes in perfumes and perfuming compositions of musky odor.
• the compounds of the invention can be used in practically all fields of modern perfumery. There can be cited here applications in fine perfumery, namely for the preparation of perfumes and colognes in which original olfactive effects can be obtained.
• perfuming ingredients belong to chemical classes as varied as alcohols, aldehydes, ketones, esters, ethers, acetates, nitrites, terpene hydrocarbons, sulfur- and nitrogen-containing heterocyclic compounds, as well as essential oils of natural or synthetic origin.
• alcohols aldehydes, ketones, esters, ethers, acetates, nitrites, terpene hydrocarbons, sulfur- and nitrogen-containing heterocyclic compounds, as well as essential oils of natural or synthetic origin.
• aldehydes ketones
• esters ethers
• acetates nitrites
• terpene hydrocarbons sulfur- and nitrogen-containing heterocyclic compounds
• the proportions in which the compounds according to the invention can be incorporated in the various products mentioned beforehand vary within a large range of values. These values depend on the nature of the article or product that one desires to perfume and the olfactive effect searched for, as well as on the nature of the coingredients in a given composition when the compounds of the invention are used in admixture with perfuming coingredients, solvents or adjuvants of current use in the art.
• the compounds of the invention are generally prepared by esterification of an alcohol of formula (IV) below with the respective acid of formula (V), or an appropriate derivative of it.
• the reaction is illustrated in the following scheme I, in which the symbols R 1 to R 5 and X have the meaning indicated in formula (I).
• an appropriate derivative of the acid (V) there can, for example, be cited the acid halides, like the chloride.
• Other appropriate derivatives are known to a person skilled in the art.
• an optically active compound of formula (I) there will be used the corresponding optically active alcohol of formula (IV) in the esterification reaction.
• the corresponding optically active alcohol of formula (IV) in the esterification reaction.
• 1-(3,3-dimethyl-1-cyclohexyl)-1-ethanol or one of its enantiomers as starting alcohol for the preparation of the preferred compounds of the invention.
• the alcohols of formula (VI) can be obtained by saponification of certain compounds of the invention of formula (I) in which X is an oxygen atom.
• MS 113(100), 138(31), 123(28), 83(23), 139(22), 69(19), 95(19), 57(17).
• This compound was prepared from the alcohol (1S,1′R)-1-(3′,3′-dimethyl-1-cyclohexyl)ethyl hydroxyacetate, obtained as described under 1)e)i). 1 g (4.67 ml) of this alcohol were added at 0° and over a period of 10 min to a suspension prepared from 0.21 g (5.14 mmol) of a 60% suspension of NaH in mineral oil and 20 ml of THF. The suspension was stirred at room temperature over 30 min, then 0.47 g (5.14 mmole) of acryloyl chloride were added after the mixture had been cooled to ⁇ 20°.

• the above-described fragrance effects are perceptible both from the novel composition and on linen washed with a powder detergent perfumed with that said composition.
• the musky aspect of the odoriferous note of the composition according to the invention which could also be smelled on the thus-treated linen, was similar to the notes typically conferred by polycyclic musky odor compounds of the indane type, i.e. a bewitching, warm, powdery, slightly animal and velvety connotation.
• the best olfactive effect was obtained with the preferred compound of the invention, namely the (1S,1′R)-isomer of the above-identified compound.
• the musky effect observed by our perfumers was olfactively closest to that typically conferred by Galaxolide®, under similar application conditions.
