Alkyl-substituted -C.sub.1 -C.sub.3 alkoxy-C.sub.6 -cycloaliphatic compounds, organoleptic uses thereof and processes for preparing same

BACKGROUND OF THE INVENTION
The instant invention relates to alkyl-substituted-C.sub.1 -C.sub.3 alkoxy-C.sub.6 -cycloaliphatic compounds defined according to the structure: ##STR4## wherein Z represents meta or para cyclohexylene or meta or para phenylene and wherein R.sub.1 and R.sub.2 are the same or different hydrogen or methyl; and wherein R.sub.3 represents C.sub.1 -C.sub.3 alkyl; and wherein the moiety ##STR5## is ortho with respect to R.sub.2 and para or meta with respect to the moiety: ##STR6## and uses of same in augmenting or enhancing the aroma of perfume compositions, perfumed articles and colognes.
There has been considerable work performed relating to substances which can be used to impart (modify, augment or enhance) fragrances to (or in) various consumable materials. These substances are used to diminish the use of natural materials, some of which may be in short supply and to provide more uniform properties in the finished product.
Long-lasting, intense, substantive green, fresh cut grass-like, leafy, woody, sweet, floral, muguet, balsamic, ozoney, waxy, fatty, aldehydic, citrusy, orange peel-like, privet hedge-like, cigar box-like, mahogany, dewy, rosy, twiggy, amber, cedarwood and earthy aromas with green, ozoney, woody, floral, muguet, minty camphorceous, piney, patchouli, rosy, celery leaf-like, fatty and aldehydic topnotes and linden blossom, cucumber, melon-like, ozoney, fatty, green, anise and fruity undertones are highly desirable in several types of perfume compositions, perfumed articles and colognes (e.g., fruity and floral fragrances).
Perfume uses of ethoxycycloalkyl derivatives are well known in the literature. Thus, Arctander "Perfume and Flavor Chemicals (Aroma Chemicals)", Volume I, published in 1969 by the author at Monograph No. 713 discloses the compound having the structure: ##STR7## for use in perfumery. Arctander discloses that the compound having the structure: ##STR8## has a powerful, pungent-floral, deep-sweet, warm odor suggestive of ylang-ylang, pandanus and other exotic flowers. Arctander indicates that this compound is useful in perfume compositions of the heavy-floral type, in artificial ylang-ylang and in various types of soap perfumes and in general as a floralizer with considerable power. Arctander further states that the compound having the structure: ##STR9## has a "peculiar nut-like, or earthy undertone". Bielstein, Volume E II 6, 488, H6, System 530a, 522-523 (abstract of Le Brazidec, Bull. Soc. Chim. France�4!, 31, 263) discloses that the compound having the structure: ##STR10## has an anisic aroma. The synthesis of this compound is disclosed by Le Brazidec and is further disclosed by Dutton, et al, Canadian Journal of Chemistry, 31 (1953), 1138, 1140. The structure: ##STR11## wherein R is methyl is shown by Bielstein, Volume E IV6 at page 3288 and is also disclosed at Chemical Abstracts, Volume 47, No. 2716h (abstract of J. Elisha Mitchell Sci. Soc., Volume 66, 171-4 (1950)). The compound having the structure: ##STR12## is also disclosed in Schoot, et al, U.S. Pat. No. 2,996,514.
The compounds having the structures: ##STR13## are indicated to be prepared by Chemical Abstracts, Volume 73, 1970, 66192c. The preparation of the compound having the structure: ##STR14## is also shown to be prepared by Bielstein, Volume E IV 6 at page 3280, Chemical Abstracts, 1961, 13386d (Zavgorodnii II) and Chemical Abstracts, Volume 49 (1955), No. 8848z (Zavgorodnii I).
Furthermore, the compound having the structure: ##STR15## is shown to be prepared by Zavgorodnii III at Chemical Abstracts, Volume 71 (1969), No. 3088m. the compound having the structure: ##STR16## is shown to be prepared using the compound having the structure: ##STR17## as a starting material according to the reaction: ##STR18## by Bielstein, E III 6, H6, 548. The compound having the structure: ##STR19## is shown to be prepared using as a starting material the compound having the structure: ##STR20## according to the reaction: ##STR21## by Bielstein, E IV 6, page 3378 and by Dutton, et al, Canadian Journal of Chemistry, 31 (1953), pages 1138, 1142.
The compound having the structure: ##STR22## is shown to be prepared by Bielstein, E III 6, H6, 505-6, System No. 530, abstract of Ipatieff, et al, Journal of American Soc., 60 (1938), 1161 and Bert, Bull. Soc. Chim., 37, 1252-70 (1925).
U.S. patent Ser. No. 5,462,923 issued on Oct. 31, 1995, Monteleone, et al describes 1-oxo-substituted and unsubstituted isobutyl-4-ethoxy-benzenes and mixtures thereof with bicyclopentadiene derivatives for use in perfumery and further discloses methods for preparing same. Said Application for U.S. patent Ser. No. 08/428,420 is a Divisional of Application for U.S. patent Ser. No. 08/299,966 filed on Sep. 2, 1994 having the same title. Both Ser. Nos. 08/299,966 and 08/428,420 disclose the compounds having the structures: ##STR23## for use in perfumery and further disclose that these compounds have "long-lasting, intense, substantive green, woody, privet hedge (Ligustrum vulgare)-like, floral, lilac, ozoney, fennel and anisic aromas with fruity, fresh green, ozoney, fresh air, "ocean breeze" and anisic topnotes".
Alkylcyclohexanols are known to be useful in the field of perfumery. Thus, "VERTENEX.RTM." is an article of commerce marketed by International Flavors & Fragrances Inc., said "VERTENEX.RTM." having the structure: ##STR24## Furthermore, "VERTENEX.RTM. HIGH CIS" is also an article of commerce marketed by International Flavors & Fragrances Inc., which has the structure: ##STR25## Furthermore, "ORIVONE", also an article of commerce marketed by International Flavors & Fragrances Inc., has the structure: ##STR26##
Para alkylcyclohexylalkyl ethers are known in the prior art. Thus, Eliel, et al, Chemical Abstracts, Volume 63, 1965, 3011g (abstract of J. Org. Chem. 30(3), pages 848-854) discloses the compound having the structure: ##STR27## Faillebin, Beilstein, Volume E II 6 at H7, No. 2, discloses the compound having the structure: ##STR28## (abstract of Faillebin, ANN. CHIM. 4, 156-82, 410-96 (1925)). Hiromu, et al, Chemical Abstracts, Volume 108, 1988 at monograph No. 108:62302g, discloses the compound having the structure: ##STR29## as being a component of an essential oil obtained from the root of Glycyrrhiza glabra (abstract of Nippon Nogei Kagaku Kashi 1987, 61(9), pages 1119-21 (Japan)). However, the aroma of this material is not disclosed nor is it indicated that the compound having the structure: ##STR30## contributes any aroma to the essential oil named.
Becker, et al in "The Relation of Structure and Odor in Substituted Cyclohexanols", Perfumer & Flavorist, Volume 15, November/December 1990 at pages 29-33 discloses the compounds having the structures: ##STR31## as having floral, fruity and earthy aroma profiles.
The alkyl-substituted-C.sub.1 -C.sub.3 alkoxy-C.sub.6 -cycloaliphatic compounds of our invention have structures different in kind and have aromas which are unexpectedly and unobviously advantageous over the aromas of the compounds having the structures: ##STR32##
Thus, nothing in the prior art discloses the unexpected, unobvious and advantageous organoleptic properties of the alkyl-substituted-C.sub.1 -C.sub.3 alkoxy-C.sub.6 -cycloaliphatic compounds of our invention.

Referring to FIGS. 32 and 33, the apparatus used in producing polymeric fragrances containing the alkyl-substituted-C.sub.1 -C.sub.3 alkoxy-C.sub.6 -cycloaliphatic compounds of our invention comprises a device for forming scented polyolefin (for example) pellets, which comprises a vat or container 212 into which a mixture of polyolefin such as polyethylene and an aromatic substance or scented material is placed (in this case at least one of the alkyl-substituted-C.sub.1 -C.sub.3 alkoxy-C.sub.6 -cycloaliphatic compounds of our invention).
The container is closed by an air-tight lid 228 and the air-tight lid 228 is clamped to the container 212 by bolts 265.
A stirrer 273 traverses the lid or cover 228 in an air-tight manner and is rotated in a suitable manner.
Container 212 having heating coils 212A which are supplied with electric current through cable 224 from a rheostat or control 216 is operated to maintain a temperature inside the container 212 such that polyethylene or other thermoplastic polymer in the container will be maintained in the molten or liquid state. It has been found advantageous to employ a colorless, odorless polymer (e.g., polyethylene) with a viscosity ranging between 180 and 220 Saybolt seconds and having a melting point in the range of 200.degree.-280.degree. F. The heater 212A is operated to maintain the upper portion of the container 212 within a temperature range of from 250.degree.-350.degree. F. The bottom portion of the container is heated by means of heating coils 212A heated through control 220 connected thereto through a connecting wire 222 to maintain the lower portion of the container within a temperature range of from 250.degree.-350.degree. F.
Thus, polymer (e.g., polyethylene) is added to container 212 and is heated from 10-12 hours whereafter a scented aroma imparting material (at least one of the alkyl-substituted-C.sub.1 C.sub.3 alkoxy-C.sub.6 -cycloaliphatic compounds of our invention) is added quickly to the melt. The material must be compatible with the polyolefin and forms a homogeneous liquid melt therewith. The scented material is of a type for the particular aroma desired and formulated specifically for the scenting purpose for which the polyolefin will be employed.
Generally, about 5-30% by weight of the scented material (containing at least one of the alkyl-substituted-C.sub.1 -C.sub.3 alkoxy-C.sub.6 -cycloaliphatic compounds of our invention) are added to the polyolefin.
After the scent imparting material (e.g., a composition containing at least one of the alkyl-substituted-C.sub.1 -C.sub.3 alkoxy-C.sub.6 -cycloaliphatic compounds of our invention) is added to the container 212, the mixture is stirred for a few minutes, for example, 5-15 minutes, and maintained within the temperature range as indicated, supra, by means of heating coils 212A.
The controls 216 and 220 are connected, respectively, through cables 214 and 222, to heating coils 212A. The said controls 216 and 220 are also connected through cables 224 and 226, respectively, to a suitable power supply of electric current for supplying the electric power to the heating coils 212A for heating purposes.
Thereafter, the valve "V" is opened permitting the mass to flow outwardly through conduit 218/232 having a multiplicity of orifices 234, adjacent to the lower side thereof. The outer end of the conduit 218/232 is closed so that the liquid polymer (e.g., polyolefin) and aroma imparting material (e.g., at least one of the alkyl-substituted-C.sub.1 -C.sub.3 alkoxy-C.sub.6 -cycloaliphatic compounds of our invention) will continuously drop through orifices 234 downwardly from conduit 232. During this time, the temperature of the polymer (e.g., polyolefin) and scent imparting material (e.g., a mixture containing at least one of the alkyl-substituted-C.sub.1 -C.sub.3 alkoxy-C.sub.6 -cycloaliphatic compounds of our invention) is accurately controlled so that a temperature in the range of from about 210.degree.-275.degree. F. will exist in the conduit 218/232. The regulation of the temperature through controls 216 and 220 is essential in order to insure temperature balance to provide for the continuous dropping or dripping of molten polymer (e.g., polyethylene) and scenting material (e.g., one or more of the para-C.sub.5 alkyl-substituted ethoxycyclohexanes of our invention) mixture through the orifices 234 at a rate which will insure the formation of droplets 236 which will fall downwardly onto a moving conveyor belt 238 caused to run between conveyor wheels 240 and 242 beneath the conduit 232.
When the droplets 236 fall onto the conveyor belt 238, they form pellets 244 which harden almost instantaneously and fall off the end of the conveyor belt 238 into a container 245 and utilized in processes as illustrated, infra.
A feature of this aspect of the process of our invention is the provision for moistening the conveyor belt 238 to insure rapid formation of the solid polymeric (e.g., polyolefin) scented pellets 244 without sticking to the belt. The conveyor belt 238 is advantageously fabricated of a material which will not normally stick to a melted plastic but a moistening means 248 insures a sufficiently cold temperature of the belt surface for an adequate formation of the pellets 244. The adequate moistening means comprises a container 250 which is continuously fed with water 254 to maintain a level for moistening a sponge element 256 which bears against the exterior of the conveyor belt 238.

The reaction takes place in the presence of a solvent and examples of solvents are 2-nitropropane having the structure: ##STR132## (the most preferred solvent); nitromethane or hydrocarbons (e.g., cyclohexane).
The temperature of reaction may be between about 0.degree. C. up to about 40.degree. C. with a preferred temperature range of from about 0.degree. C. up to about 5.degree. C.
The preferred reactants of the genus: ##STR133## are those wherein X is chloro due to economic reasons.
At the end of the reaction, the reaction mass is distilled in order to yield substantially pure materials defined according to the structure: ##STR134## wherein R.sub.1, R.sub.2 and R.sub.3 are defined, supra. The compounds defined according to the structure: ##STR135## are then further reacted by means of reduction using hydrogen and an appropriate hydrogenation catalyst for the reaction: ##STR136## The hydrogenation catalyst used and the conditions of the hydrogenation reaction may be varied and in so varying such catalysts and conditions of reaction, various ratios of cis and trans isomers will be produced. Thus, when the hydrogenation is carried out using 3% ruthenium on carbon catalyst at a temperature in the range of from 110.degree. up to 145.degree. C. and at a pressure in the range of from 400 up to 700 psig for a period of time of from 0.25 up to 10 hours, approximately at 50:50 cis and trans mixture of compounds will result. On the other hand, a preponderant amount of cis isomer will be produced when using ruthenium on aluminum oxide or rhodium on aluminum oxide catalyst (with the ruthenium or rhodium being from about 3 up to about 8% by weight of the catalyst) at a temperature of from about 80.degree. up to about 100.degree. C.; at a pressure of about 400 psig; and for a period of time of from about 0.25 up to about 3 hours. In both cases, in the hydrogenation reaction, methanol, ethanol or n-propanol solvents are to be used.
With reference to the reaction sequence: ##STR137## in the compound: ##STR138## also shown as:
M.sub.C (OH).sub.P
M.sub.C represents an alkali metal such as sodium, potassium or lithium or an alkaline earth metal such as calcium or magnesium. When M.sub.C represents an alkali metal, P is 1 and when M.sub.C is an alkaline earth metal, P is 2. Preferably, M.sub.C is sodium. Preferably, the ethoxylation reagent is diethyl sulfate, although ethoxylation reagents such as ethyl chloride, ethyl bromide and ethyl iodide are also useful ethoxylation reagents.
Preferrably, the methoxylation reagent is dimethyl sulfate, although methoxylation reagents such as methyl chloride, methyl bromide and methyl iodide are also useful methoxylation reagents.
An additional ethoxylation reagent is a mixture of ethyl alcohol and 93% concentrated sulfuric acid with the ratio of the ethyl alcohol:concentrated sulfuric acid being 50:50 (weight:weight).
With reference to the reaction: ##STR139## this reaction can take place in the presence of a 3% ruthenium/carbon catalyst at 110.degree.-145.degree. C.; a pressure of 400-700 psig and a time of reaction of from 0.25 up to 10 hours, whereby the resulting mixture is a 50:50 mixture of cis:trans isomers, for example, the cis isomer having the structure: ##STR140## and the trans isomer having the structure: ##STR141##
Alternatively, other ruthenium-based hydrogenation catalysts may be used and these ruthenium catalysts are disclosed and claimed in U.S. Pat. No. 5,403,805 issued on Apr. 4, 1995, the specification for which is incorporated herein by reference. Furthermore, other ruthenium-based catalysts can be used, for example, those set forth in U.S. Pat. No. 5,426,216 issued on Jun. 20, 1995, the specification for which is incorporated by reference herein.
Reaction mixtures preponderant in the cis isomers such as the isomer having the structure: ##STR142## can be produced by using ruthenium on aluminum oxide catalysts or rhodium on aluminum oxide catalysts with the amount of ruthenium or rhodium being from about 3 up to about 8% by weight of the catalyst; at a temperature in the range of 80.degree.-100.degree.

One or more of the alkyl-substituted-C.sub.1 -C.sub.3 alkoxy-C.sub.6 -cycloaliphatic compounds prepared in accordance with the processes of our invention and one or more auxiliary perfume ingredients including, for example, alcohols, aldehydes, ketones, terpenic hydrocarbons, nitriles, esters, lactones, ethers other than the ethers of our invention, natural essential oils and synthetic essential oils may be admixed so that the combined odors of the individual components produce a pleasant and desired fragrance, particularly and preferably in the citrus, fruity and woody types of fragrances. Such compositions usually contain:
(a) the main note or the "bouquet" or foundation stone of the composition;
(b) modifiers which round off and accompany the main note;
(c) fixatives which include odorous substances which lend a particular note to the perfume throughout all stages of evaporation and substances which retard evaporation; and
(d) topnotes which are usually low boiling, fresh smelling materials.
In perfume compositions, it is the individual components which contribute their particular olfactory characteristics, however, the overall sensory effect of the perfume compositions will be at least the sum total of the effects of each of the ingredients. Thus, the alkyl-substituted-C.sub.1 -C.sub.3 alkoxy-C.sub.6 -cycloaliphatic compounds of our invention produced in accordance with the processes of our invention can be used to alter, modify or enhance the aroma characteristics of a perfume composition, for example, by utilizing or moderating the olfactory reaction contributed by another ingredient in the composition. In the alternative, the alkyl-substituted-C.sub.1 -C.sub.3 alkoxy-C.sub.6 -cycloaliphatic compounds of our invention can be used to formulate a perfume composition by themselves.
The amount of the alkyl-substituted-C.sub.1 -C.sub.3 alkoxy-C.sub.6 -cycloaliphatic compounds prepared in accordance with the processes of our invention which will be effective in perfume compositions as well as in perfumed articles (e.g., anionic, cationic, nonionic or zwitterionic detergents, soaps, fabric softener compositions, fabric softener articles and perfumed polymers) and colognes depends upon many factors including the other ingredients, their amounts and the effects which are desired. It has been found that perfume compositions containing as little as 0.01% of at least one of the alkyl-substituted-C.sub.1 -C.sub.3 alkoxy-C.sub.6 -cycloaliphatic compounds of our invention prepared in accordance with the processes of our invention or even less (e.g., 0.005%) can be used to impart, augment or enhance green, fresh cut grass-like, leafy, woody, sweet, floral, muguet, balsamic, ozoney, waxy, fatty, aldehydic, citrusy, orange peel-like, privet hedge (Ligustrum vulgare)-like, cigar box-like, mahogany, dewy, rosy, twiggy, amber, cedarwood, and earthy aromas with green, ozoney, woody, floral, muguet, minty, camphoraceous, piney, patchouli, rosy, celery leaf-like, fatty and aldehydic topnotes and with linden blossom, cucumber, melon-like, ozoney, fatty, green, anise and fruity undertones to soaps, cosmetics, anionic, cationic, nonionic or zwitterionic detergents, fabric softener articles, micorporous polymers, particularly acrylic resins, polyethylenes and other products. The amount employed can range up to 100% of the fragrance components and will depend on considerations of cost, nature of the end product, the effect desired on the finished product and the particular fragrance sought.
The alkyl-substituted-C.sub.1 -C.sub.3 alkoxy-C.sub.6 -cycloaliphatic compounds of our invention prepared in accordance with the processes of our invention are useful (taken alone or together with other ingredients in perfume compositions) as (an) olfactory component(s) in detergents and soaps, space odorants and deodorants, perfumes, colognes, toilet water, bath preparations such as creams, deodorants, hand lotions and sun screens; powders such as talcs, dusting powders, face powders, microporous "perfumed" slow release polymers and the like.
When used as (an) olfactory component(s) in perfumed articles, as little as 0.005% of at least one of the alkyl-substituted-C.sub.1 -C.sub.3 alkoxy-C.sub.6 -cycloaliphatic compounds prepared in accordance with the processes of our invention, will suffice to impart, augment or enhance green, fresh cut grass-like, leafy, woody, sweet, floral, muguet, balsamic, ozoney, waxy, fatty, aldehydic, citrusy, orange peel-like privet hedge (Ligustrum vulgare)-like, cigar box-like, mahogany, dewy, rosy, twiggy, amber, cedarwood and earthy aromas with green, ozoney, woody, floral, muguet, minty, camphoraceous, piney, patchouli, rosy, celery leaf-like, fatty and aldehydic topnotes and linden blossom, cucumber, melon-like, ozoney, fatty, green, anise and fruity undertones. Generally no more than 6% of at least one of the alkyl-substituted-C.sub.1 -C.sub.3 alkoxy-C.sub.6 -cycloaliphatic compounds of our invention based on the ultimate end product is required in the perfumed article. Accordingly, the range of use of the alkyl-substituted-C.sub.1 -C.sub.3 alkoxy-C.sub.6 -cycloaliphatic compounds of our invention in perfumed articles, per se, is from about 0.005% up to about 6% by weight based on the perfumed article.
In addition, the perfume composition or fragrance composition of our invention can contain a vehicle or carrier for the alkyl-substituted-C.sub.1 -C.sub.3 alkoxy-C.sub.6 -cycloaliphatic compounds prepared in accordance with the processes of our invention. The vehicle can be a liquid such as a non-toxic alcohol, e.g., ethyl alcohol; a non-toxic glycol, e.g., propylene glycol or dipropylene glycol or the like. The carrier can be an absorbent solid such as a gum (e.g., gum arabic, guar gum or xanthan gum or combinations thereof) or components for encapsulating the composition (such as by coacervation) or using prepolymers such as urea-formaldehyde prepolymers which are able to form a urea-formaldehyde polymer capsule around a liquid perfume center.
It will thus be apparent that the alkyl-substituted-C.sub.1 -C.sub.3 alkoxy-C.sub.6 -cycloaliphatic compounds prepared in accordance with the processes of our invention can be utilized to alter, modify or enhance sensory properties particularly organoleptic properties such as fragrances of a wide variety of consumable materials.
The following Examples I-VII, inclusive, set forth means for preparing the alkyl-substituted-C.sub.1 -C.sub.3 alkoxy-C.sub.6 -cycloaliphatic compounds of our invention. The examples following Example VII, infra, set forth illustrations of organoleptic utilities of the alkyl-substituted-C.sub.1 -C.sub.3 alkoxy-C.sub.6 -cycloaliphatic compounds of our invention.
