Title: Methyl substituted oxobicyclo-4,4,0-decane derivatives, process for preparing same and organoleptic uses thereof

Description:
BACKGROUND OF THE INVENTION 
     The instant invention covers compounds having the generic structure: ##STR4## wherein the dashed line represents a carbon-carbon single bond or a carbon-carbon double bond; wherein X represents the moieties: ##STR5## wherein R 1 , R 2 , R 3  and R 4  represent hydrogen or methyl with the provisos that (i) at least three of R 1 , R 2 , R 3  and R 4  represent hydrogen and (ii) when the dashed line is a carbon-carbon single bond and x is: ##STR6## then one of R 1 , R 2 , R 3  or R 4  is methyl and the other represents hydrogen; wherein R 5  represents hydrogen, MgX, MgR 7 , CdR 7 , ZnR 7 , Na, K or Li; wherein X represents Chloro, Bromo or Iodo; wherein R 6  represents hydrogren or methyl; and wherein R 7  represents lower alkyl; as well as uses of the above compounds, with the exception of the organometallic compounds of the genus, for augmenting or enhancing the aromas and/or taste of consumable materials. 
     Materials which can provide minty, camphoraceous, dry woody, sweet, fruity, woody patchouli, green, herbaceous, basil-like, citrus-like, bergamot-like, lime-like, grapefruit-like, peppery, precious-woody, vertiver-like, fresh, musky, lavender thyme, rosemary, sweaty, rooty and earthy aromas with floral, citrus, lavender and amber top-notes and backgrounds are known in the art of perfumery. Many of the natural materials which provide such fragrances and contribute desired nuances to perfumery compositions are high in cost, vary in quality from one batch to another and/or are generally subject to the ususal variations of natural products. 
     By the same token, materials which can provide oriental, insence-like, peppery, blueberry-like, eucalyptol-like, minty, camphoraceous, floral, musk-like, rose-like, black pepper, spicey, patchouli, cooling, sandalwood-like, woody and walnut-like aromas with oriental, black pepper, peppery, minty, eucalyptol-like, camphoraceous, floral, rosey and patchouli-like tastes are well known in the art of flavoring for foodstuffs, toothpastes, chewing gums and medicinal products. Many of the natural materials which provide such flavor nuances and contribute desired nuances to flavor and compositions are high in cost, vary in quality from one batch to another and/or are generally subject to the usual variations of natural products. 
     Sweet, fruity, berry-like, cooling, woody and floral aroma and taste nuances are known in the art of the production of smoking tobaccos and smoking tobacco articles. Many of the natural materials which provide such aroma and taste nuances to smoking tobacco compositions are high in cost, vary in quality from one batch to another and/or are generally subject to the usual variations of natural products. 
     There is, accordingly, a continuing effort to find synthetic materials which will replace, enhance or augment the essential flavor and/or fragrance notes provided by natural essential oils or compositions thereof. Unfortunately, many of these synthetic materials either have the desired nuances only to a relatively small degree or else contribute undesirable or unwanted odor to the consumable compositions. The search for materials which can provide more refined patchouli-like aromas, for example, have been difficult and relatively costly in the areas of both natural products and synthetic products. 
     Artificial flavoring agents for foodstuffs have received increasing attention in recent years. For many years such food flavoring agents have been preferred over natural flavoring agents at least in part due to their diminished cost and their reproducible flavor qualities. For example, natural food flavoring agents such as extracts, concentrates and the like are often subject to wide variations due to changes in quality, type and treatment of the raw materials. Such variations can be reflected in the end products and result in unfavorable flavor characteristics in said end product. Additionally, the presence of the natural product in the ultimate food may be undesirable because of increased tendency to spoil. This is particularly troublesome in food and food uses where such products as dips, soups, chips, sausages, gravies and the like are apt to be stored prior to use. 
     The fundamental problem in creating artificial flavor agents is that the artificial flavor to be achieved be as natural as possible. This generally proves to be a difficult task since the mechanism for flavor development in many foods, medicinal products, chewing gums and toothpastes is not completely known. This is noticable in products having licorice, citrusy and vegetable flavor characteristics particularly. 
     Even more desirable are products that can serve to substitute for difficult-to-obtain natural perfumery oils and at the same time substitute for natural flavoring ingredients in foodstuffs, chewing gums, medicinal products, toothpastes, and smoking tobaccos. 
     Oxobicyclo compounds are known in the prior art. Thus, Nagakura, et al., Bull. Chem. Soc. Japan Vol. 48(10), 2995-6 (October 1975) discloses the compound defined according to the generic structure: ##STR7## produced by the reaction: ##STR8## wherein one of R 1  &#39;, R 2  &#39;, R 3  &#39; or R 4  &#39; is methyl and the others represent hydrogen. In addition, Conia and Rouessac, Bull. Soc. Chem. France 1953(page 1925 et seq.) discloses processes for producing oxobicyclo compounds according to the following reaction steps: ##STR9## 
     The use of oxotricyclic derivatives in perfumery is disclosed in U.S. Pat. No. 3,996,169, issued on Dec. 7, 1976. Thus, in U.S. Pat. No. 3,996,169, a genus defined according to the structure: ##STR10## is disclosed, wherein R 1 , R 2 , R 3 , R 4 , R 5 , R 6 , R 7 , R 8 , R 9  and R 10  is selected from the group consisting of hydrogen and methyl; and wherein the dashed line may be a carbon-carbon single bond or a carbon-carbon double bond. Members of this genus are indicated to be capable of altering, modifying, enhancing or emparting an aroma of or to consumable materials including colognes, perfumes and perfumed articles and such an aroma is of a patchouli type. 
     Arctander, &#34;Perfume and Flavor Chemicals&#34;, 1969, Vol. 1 discloses the use in perfume compositions and foodstuff flavors of &#34;decalinol&#34;, &#34;decalone&#34;, &#34;fenchone&#34;, and &#34;fenchyl alcohol&#34;, thusly: 
     &#34;(i) 1385: FENCHONE laevo-Fenchone. (dextro- is known but less common as a fragrance material). 
     1,3,3-Trimethyl-2-norbornanone. 
     1,3,3-Trimethyl bicyclo-1,2,2-heptone-2. ##STR11## Warm-camphoraceous, powerful and diffusive, basically sweet odor. Warm, somewhat burning and bitter taste with a medicinal note. 
     This ketone finds some use as a masking odor in industrial fragrances. It is also used in the reconstruction of Fennel oil and a few other essential oils. 
     In spite of its rather unpleasant taste, it is used in various Berry complex flavors, in Spice complexes and in certain types of Liquer flavoring. 
     The concentration used is about 0.1 to 5 ppm in the finished product. 
     (ii) 1387: FENCHYL ALCOHOL 
     1,3,3-Trimethyl-2-norbornanol. 
     1,3,3-Trimethyl bicyclo-1,2,2-heptanol-2. 
     2-Fenchanol. 
     Fenchol. ##STR12## The racemic alpha-Fenchol has a somewhat lower melting point, and the beta-Fenchols are all liquid at room temperature. 
     Fenchol made by reduction of Fenchone from Cedar-leaf oil is usually a mixture of several isomers, including the crystalline alpha-isomers. The beta-isomer forms a crystalline Hydrate which may be solid at room temperature. 
     Almost insoluble in water, soluble in alcohol, miscible with oils. Powerful and diffusive, Camphor-like, but sweeter and more Citrus-like almost Lime-like odor with more or less of an earthy-dry character, according to the composition and isomer-ratio. 
     The taste is somewhat bitter-Lime-like, camphoraceous and slightly woody-musty. 
     This interesting alcohol (or mixed alcohols) finds use in perfume compositions ranging from woody or herbaceous to Citrus-Lime and even certain floral types. It produces power and `lift` to floral fragrances, and solid background to Lime and other Citrus bases, having the advantage over the Terpenes in being very stable in soap. 
     Fenchyl alcohol is also used in flavor compositions such as Strawberry and other berries, Lime and Spice, etc. 
     The concentration is normally low, e.g. 0.2 up to 5 ppm in the finished product. 
     (iii) 824: TRANS-DECAHYDRO-BETA-NAPHTHOL 
     trans-beta-Decanol. 
     (sometimes called &#34;Decalinol&#34;.) 
     Bicyclo-4,4,0-Decanol ##STR13## Colorless viscous liquid, solidifying in the cold to an opaque mass. The presence of variable amounts of the cis-isomer is mainly responsible for the variations in physical appearance of this material. 
     Mild, sweet, slightly camphoraceous-woody, also warm and mildly spicy odor of fair tenacity. The odor has been compared to that of Dihydrocarveol, but such description does not help many perfumers. 
     Practically insoluble in water, soluble in alcohol and oils. 
     This alcohol has been used, and is still used on a mosdest scale, in perfume compositions, mostly in connection with woody and camphoraceous fragrance types, including the Ionones, Cyclohexylderivatives, etc. Several of its esters (see following monographs) have been more successful as perfume materials). 
     However, since the Ambregis- and Sandalwood-notes, which are represented to a certain degree in the esters, can be obtained with much superior beauty by way of modern perfume chemicals, there is reason to believe that the Decahydronaphthyl series will eventually become obsolete. 
     Prod.: by catalytic hydrogenation of beta-Naphthol. The reaction yields a mixture of cis- and trans- isomers, but the perfumers generally prefer the trans-isomer or a material primarily consisting of that isomer. 
     (iv) 830: BETA-DECALONE 
     Decahydro naphthalone 
     The commercial products consist of a mixture of cis- and trans-isomers. ##STR14## Viscous colorless liquid, solidifying in the cold. Practically insoluble in water, soluble in alcohol and oils. 
     The cis-isomer is liquid and boils at 247° C. 
     The trans-isomer is solid below 6° C. and boils at 241° C. 
     Semi-dry, tenacious odor resembling part of the Ambregris-picture, also woody, remotely reminiscent of Sandalwood. Odor variations are observed in materials from different sources of supply. 
     This ketone has found a little use in perfume compositions, including soap perfumes, where it can introduce pleasant background notes in support of Musk Ambrette, Labdanum, Methylionones, etc. 
     Recent development in Ambregris chemicals has brought much superior materials in the hands of the perfumer, and it is very likely that the title material, and many of its relatives, will become obsolete within the next decade or so. 
     Prod.: by oxidation of beta-Decalol with Chromic acid mixture.&#34; 
     U.S. Pat. No. 3,932,515 discloses the use of the compound having the structure: ##STR15## in perfumery and specifically indicates that such compound has a woody aroma of high tenacity. U.S. Pat. No. 3,932,516 discloses the compound having the structure: ##STR16## and indicates that this compound is useful in perfumery due to its woody character. 
     None of the references cited above, or for that matter any other references discloses compounds which have a close structural relationship to the genus of compounds of the instanct invention. In any event, the organoleptic properties of the compounds of the references are different in kind from those of the compounds of the instant invention.

     THE INVENTION 
     It has now been discovered that novel solid and liquid foodstuff, chewing gum, medicinal product and toothpaste compositions and flavoring compositions therefor having oriental, incense-like, peppery, blueberry-like, eucalyptol-like, minty, campohoraceous, floral, musk-like, rose-like, black pepper, spicey, patchouli, cooling, sandalwood-like, woody and walnut-like aromas with oriental, black pepper-like, peppery, minty, eucalyptol-like, camphoraceous, floral, rosey and patchouli-like tastes; as well as novel smoking tobacco and smoking tobacco flavoring compositions having sweet, fruity, berry-like, cooling, woody and floral aromas prior to smoking and on smoking in both the mainstream and the sidestream; as well as novel perfume compositions, colognes and perfumed articles (e.g. solid or liquid anionic, cationic, nonionic and zwitterionic detergents, fabric softener compositions, cosmetic powders and prior-added fabric softener articles) having intense and pleasant minty, camphoraceous, dry woody, sweet fruity, patchouli, woody patchouli, green, herbaceous, basil-like, citrus-like, bergamot-like, lime-like, grapefruit-like, peppery, precious woody, vetiver, fresh, musky, lavender, thyme, rosemary, sweaty, rooty and earthy aromas with floral, citrus, lavender, and amber-like top-notes and undertones may be provided by the utilization of one or more methyl substituted oxobicyclo-4,4,0-decane derivatives of our invention having the generic structure: ##STR86## wherein X is a moiety which is either: ##STR87## wherein the dashed line represents a carbon-carbon single bond or a carbon-carbon double bond; wherein R 1 , R 2 , R 3  and R 4  represent hydrogen or methyl with the provisos (i) that at least three of R 1 , R 2 , R 3  and R 4  represent hydrogen and the other of R 1 , R 2 , R 3  and R 4  is methyl and (ii) that when the dashed line is a carbon-carbon single bond and X is the moiety: ##STR88## then one of R 1 , R 2 , R 3  or R 4  is methyl and the other of R 1 , R 2 , R 3  or R 4  is hydrogen; wherein R 5  represents hydrogen and R 6  represents hydrogen or methyl in foodstuffs, chewing gums, toothpasts, medicinal products, perfume compositions, perfumed articles, colognes and smoking tobaccos as well as smoking tobacco substitutes. 
     Unless otherwise specified, representations herein of organic structures are intended to indicate a &#34;cis&#34; isomer a &#34;trans&#34; isomer, or a mixture of &#34;cis&#34; and &#34;trans&#34; isomers with respect to the plane of the cyclohexane ring. Thus, the generic structure: ##STR89## may either be a &#34;cis&#34; isomer, for example, having the structure: ##STR90## or a &#34;trans&#34; isomer having the structure: ##STR91## 
     Furthermore, the &#34;trans&#34; structure: ##STR92## with respect to the methyl moiety at the &#34;-9, 10-&#34; position may further be specified, for example, by the structure: ##STR93## wherein X is &gt;CHOH. 
     The methyl substituted oxobicyclo-4,4,0-decane derivatives of our invention may be prepared by first reacting 2,6,6-trimethylcyclohex-2-enone with a substituted butadiene such as butadiene, isoprene or piperylene according to the reaction: ##STR94## The ratio of diene:ketone may be in the range of from about 1:1 (mole ratio) up to about 10:1 with a mole ratio of diene:ketone preferably being about 1.5:1. The reaction may be carried out in the presence of a Lewis acid catalyst such as aluminum thrichloride, zinc chloride, titanium tetrachloride, BF 3 .etherate, ethyl aluminum dichloride, diethyl aluminum chloride, and other Lewis acid catalysts. Reaction may be carried out in the presence of or in the absence of a solvent. When using a solvent, solvents such as toluene, xylene and chlorinated solvents may be used which are inert to the reactants. 
     The reaction may be carried out at the temperatures of between -15° C. and 100° C.; preferably at -10° C. up to about 50° C. The reaction may be carried out at atmospheric pressure, super atmospheric pressures and subatmospheric pressures. Most conveniently, economically and preferably the reaction is carried out at atmospheric pressure. 
     The resulting ketone may be used as is for its organoleptic properties, in which case, the resulting ketone is purified as by standard extraction and fractional distillation processes. The isomers resulting may be commerically separated as by means of high pressure liquid chrometography. 
     The resulting ketone may, however, be further reacted either (i) by means of a reduction reaction to form a saturated ketone according to the reaction: ##STR95## or (ii) by reduction of the ketone moiety to form an alcohol by means of the reaction: ##STR96## or (iii) by means of reaction with an organometallic compound such as a Grignard reagent followed by subsequent hydrolysis whereby the 1-methyl-1-hydroxy derivative is formed according to the reaction scheme: ##STR97## wherein M is either of MgX, Na, K, Li, Cd, Mg or Zn; wherein X is chloro, bromo or iodo; wherein R 7  is lower alkyl; wherein when M is Cd, Mg or Zn, N=1 and when m is MgX, Na, K or Li, n=0. 
     The resulting unsaturated alcohol may further be reduced as by hydrogenation, for example, according to the reaction: ##STR98## 
     When a hydrogenation reaction is carried out, e.g.: ##STR99## a hydrogenation catalyst is used, for example, a palladium catalyst or a palladium-on-carbon catalyst whereby a saturated ketone is formed. The hydrogenation is preferably carried out at temperatures in the range of from about 20° C. up to about 100° C. at pressures of between about 30 psig and about 300 psig; preferably at pressures of between 40 psig and 60 psig. At the end of the hydrogenation, the resulting ketone may be used for its organoleptic properties in which case the resulting ketone is purified by means of standard extraction procedures and standard fractional distillation procedures. In the event that two or more isomers are formed as a result of the reaction, the resulting isomers may be separated as by means of fractional distillation or even by means of high pressure liquid chomotography. 
     When the ketone moiety is reduced to the alcohol as by means of the reaction: ##STR100## this reaction takes place using a reducing agent such as lithium aluminum hydride, sodium boro hydride, lithium borohydride. Al(isobutyl) 2  H or &#34;Vitride®&#34; which is NaAlH 2  (OCH 2  CH 2  OCH 3 ) 2 . However, the ketone moiety may be reduced to the alcohol moiety by means of high pressure and high temperature hydrogenation, e.g. carrying out a hydrogenation at about 90°-150° C. at pressure of between 50 and 5,000 psig. The higher pressure and higher temperature range will give rise to shorter reaction time. 
     The resulting ketone may be used as is or may be further reacted with an organometallic compound which is subsequently hydrolyzed. Thus, in the resulting ketone is to be used &#34;as is&#34; for its organoleptic properties, said ketone will be further &#34;workup&#34; as by means of standard extraction procedures and/or fractional distillation procedures. In the event that pure isomers are desired and indeed pure stereoisomers are desired, high pressure liquid chromotographic techniques may be used as well as standard stereoisomer-separation techniques using pure stereoisomers which will react with a functional group followed by decomposition after fractional crystallization, for example. 
     When the resulting ketone is reacted with an organo-metallic compound to form a second organometallic compound which is subsequently hydrolized according to the reaction procedure: ##STR101## 
     In the reaction of the oxabicyclic ketone with the organometallic compound having the structure: 
     
         CH.sub.3 --M(R.sub.7).sub.n 
    
     it is preferred that the compound having the structure: 
     
         CH.sub.3 --M(R.sub.7).sub.n 
    
     be reacted in an appropriate solvent such as benzene, benzene/tetrahydrofuran, tetrahydrofuran or diethyl ether. It is also preferred that the mole ratio of organometallic compound having the structure:

     be about 1:1. It is further preferred that the reaction temperature be from about -5° C. up to about 40° C. with the most preferred temperature being 20° C.-30° C. 
     The hydrolysis of the organometallic compound to form the resulting alcohol is carried out using a mineral acid such as dilute aqueous hydrochloric acid, sulfuric acid or phosphoric acid or other protonic acids such as paratoluenesulfonic acid. The hydrolysis preferably takes place at 0°-20° C. At the end of this reaction, the reaction product is isolated by means of standard isolation techniques such as fractional distillation and, if desired, preparative GLC or high pressure GLC for isolation of the end product. 
     An alternative method for preparing unsaturated alcohols of our invention is to react the ketones resulting from the Diels-Alder reaction with isopropyl magnisium halide. In view of the sterically hindered position of the ketone (as a result of the methyl groups &#34;alpha&#34; to the ketone moity), an oxygrignard is formed from the ketone without alkylation at the ketone moity. The resulting oxygrignard may then be hydrolized using standard hydrolisis conditions as set forth above to yield the resulting alcohol. The reaction illustrating this procedure is set forth as follows: ##STR102##

     When the methyl substituted oxobicyclo-4,4,0-decane derivatives of our invention are used as food flavor adjuvants, the nature of the co-ingredients included with each of the said methyl substituted oxobicyclo-4,4,0-decane derivatives in formulating the product composition will also serve to alter, modify, augment or enhance the organoleptic characteristics of the ultimate foodstuff treated therewith. 
     As used herein in regard to flavors, the terms &#34;alter&#34;, &#34;modify&#34; and &#34;augment&#34; in their various forms means &#34;supplying or imparting flavor character or note to otherwise bland, relatively tasteless substances or augmenting the existing flavor characteristic where a natural flavor is deficient in some regard or supplementing the existing flavor impression to modify its quality, character or taste&#34;. 
     The term &#34;enhance&#34; is used herein to mean the intensification of a flavor or aroma characteristic or note without the modification of the quality thereof. Thus, &#34;enhancement&#34; of a flavor or aroma means that the enhancement agent does not add any additional flavor note. 
     As used herein, the term &#34;foodstuff&#34; includes both solid and liquid ingestible materials which usually do, but need not, have nutritional value, Thus, foodstuffs, include soups, convenience foods, beverages, dairy products, candies, vegetables, cereals, soft drinks, snacks and the like. 
     As used herein, the term &#34;medicinal product&#34; includes both solids and liquids which are ingestible non-toxic materials which have medicinal value such as cough syrups, cough drops, aspirin and chewable medicinal tablets.

Incorporated with the gum base in admixture therewith may be plasticizers or softening agents, e.g., glycerine; and a flavoring composition which incorporates one or more of the methyl substituted oxobicyclo-4,4,0-decane derivatives of our invention, and in addition, sweetening agents which may be sugars, including sucrose or dextrose and/or artificial sweeteners such as cyclamates or saccharin. Other optional ingredients may also be present. 
     Substances suitable for use herein as co-ingredients or flavoring adjuvants are well known in the art for such use, being extensively described in the relevant literature. It is a requirement that any such material be &#34;ingestibly&#34; acceptable and thus non-toxic and otherwise non-deleterious particularly from an organoleptic standpoint whereby the ultimate flavor and/or aroma of the consumable material used is not caused to have unacceptable aroma and taste nuances.

     The specific flavoring adjuvant selected for use may be either solid or liquid depending upon the desired physical form of the ultimate product, i.e., foodstuff, whether simulated or natural, and should, in any event, (i) be organoleptically compatible with the methyl substituted oxobicyclo-4,4,0-decane derivatives of our invention by not covering or spoiling the organoleptic properties (aroma and/or taste) thereof; (ii) be non-reactive with the methyl substituted oxobicyclo-4,4,0-decane derivatives of our invention and (iii) be capable of providing an environment in which the methyl substituted oxobicyclo-4,4,0-decane derivatives can be dispersed or admixed to provide a homogeneous medium. In addition, selection of one or more flavoring adjuvants, as well as the quantities thereof will depend upon the precise organoleptic character desired in the finished product. Thus, in the case of flavoring compositions, ingredient selection will vary in accordance with the foodstuff, chewing gum, medicinal product or toothpaste to which the flavor and/or aroma are to be imparted, modified, altered or enhanced. In contradistinction, in the preparation of solid products, e.g., simulated foodstuffs, ingredients capable of providing normally solid compositions should be selected such as various cellulose derivatives. 
     As will be appreciated by those skilled in the art, the amount of methyl substituted oxobicyclo-4,4,0-decane derivatives employed in a particular instance can vary over a relatively wide range, depending upon the desired organoleptic effects to be achieved. Thus, correspondingly, greater amounts would be necessary in those instances wherein the ultimate food composition to be flavored is relatively bland to the taste, whereas relatively minor quantities may suffice for purposes of enhancing the composition merely deficient in natural flavor or aroma. The primary requirement is that the amount selected to be effective, i.e., sufficient to alter, modify or enhance the organoleptic characteristics of the parent composition, whether foodstuff per se, chewing gum, per se, medicinal product per se, toothpaste per se, or flavoring composition. 
     The use of insufficient quantities of methyl substituted oxobicyclo-4,4,0-decane derivatives will, of course, substantially vitiate any possibility of obtaining the desired results while excess quantities prove needlessly costly and, in extreme cases, may disrupt the flavor-aroma balance, thus proving self-defeating. Accordingly, the terminology &#34;effective amount&#34; and &#34;sufficient amount&#34; is to be accorded a significance in the context of the present invention consistent with the obtention of desired flavoring effects. 
     Thus, and with respect to ultimate food compositions, chewing gum compositions, medicinal product compositions and toothpaste compositions, it is found that quantities of methyl substituted oxobicyclo-4,4,0-decane derivatives ranging from a small but effective amount, e.g., 0.01 parts per million up to about 100 parts per million based on total composition are suitable. Concentrations in excess of the maximum quantity stated are not normally recommended, since they fail to prove commensurate enhancement of organoleptic properties. In those instances, wherein the methyl substituted oxobicyclo-4,4,0-decane derivatives are added to the foodstuff as an integral component of a flavoring composition, it is, of course, essential that the total quantity of flavoring composition employed be sufficient to yield an effective methyl substituted oxobicyclo-4,4,0-decane derivative concentration in the foodstuff product. 
     Food flavoring compositions prepared in accordance with the present invention preferably contain the methyl substituted oxobicyclo-4,4,0-decane derivatives in concentrations ranging from about 0.01% up to about 15% by weight based on the total weight of the said flavoring composition. 
     The composition described herein can be prepared according to conventional techniques well known as typified by cake batters and fruit drinks and can be formulated by merely admixing the involved ingredients within the proportions stated in a suitable blender to obtain the desired consistency, homogeneity of disperseion, etc. Alternatively, flavoring compositions in the form of particulate solids can be conveniently prepared by mixing the methyl substituted oxobicyclo-4,4,0-decane derivatives with, for example, gum arabic, gum tragacanth, carrageenan and the like, and thereafter spray-drying the resultant mixture whereby to obtain the particular solid product. Pre-prepared flavor mixes in powder form, e.g., a fruit-flavored powder mix are obtained by mixing the dried solid components, e.g., starch, sugar and the like and methyl substituted oxobicyclo-4,4,0-decane derivatives in a dry blender until the requisite degree of uniformity is achieved.

     An additional aspect of our invention provides an organoleptically improved smoking tobacco product and additives therefor, as well as methods of making the same which overcome problems heretofore encountered in which specific desired sweet, fruity, berry-like, woody and floral flavor characteristics of natural tobacco (prior to smoking and, on smoking, in the mainstream and in the sidestream) as well as cooling effects, are created or enhanced or modified or augmented and may be readily controlled and maintained at the desired uniform level regardless of variations in the tobacco components of the blend. 
     This invention further provides improved tobacco additives and methods whereby various desirable natural aromatic tobacco flavoring characteristics with sweet, fruity, berry-like, cooling, woody and floral notes may be imparted to smoking tobacco products and may be readily varied and controlled to produce the desired uniform flavoring characteristics. 
     In carrying out this aspect of our invention, we add to smoking tobacco materials or a suitable substitute therefor (e.g., dried lettuce leaves) an aroma and flavor additive containing as an active ingredient one or more methyl substituted oxobicyclo-4,4,0-decane derivatives of our invention. 
     In addition to the methyl substituted oxobicyclo-4,4,0-decane derivatives of our invention other flavoring and aroma additives may be added to the smoking tobacco material or substitute therefor either separately or in mixture with the methyl substituted oxobicyclo-4,4,0-decane derivatives as follows: 
     I. Synthetic Materials 
     Beta-ethyl-cinnameldehyde; 
     Eugenol; 
     Dipentene; 
     Damascenone; 
     Maltol; 
     Ethyl maltol; 
     Delta undecalactone; 
     Delta decalactone; 
     Benzaldehyde; 
     Amyl acetate; 
     Ethyl butyrate; 
     Ethyl valerate; 
     Ethyl acetate; 
     2-Hexenol-1; 
     2-Methyl-5-isopropyl-1,3-nonadiene-8-one; 
     2,6-Dimethyl-2,6-undecadiene-10-one; 
     2-Methyl-5-isopropylacetophenone; 
     2-Hydroxy-2,5,5,8a-tetramethyl-1-(2-hydroxyethyl)decahydronaphthalene; 
     Dodecahydro-3a,6,6,9a-tetramethylnaphtho-(2,1-b)furan 
     4-Hydroxyhexanoic acid, gamma lactone; and 
     Polyisoprenoid hydrocarbons defined in Example V of U.S. Pat. No. 3,589,372 issued on June 29, 1971. 
     II. Natural Oils 
     Celery seed oil; 
     Coffee Extract; 
     Bergamot Oil; 
     Cocoa extract; 
     Nutmeg Oil; and 
     Origanum Oil. 
     An aroma and flavoring concentrate containing one or more methyl substituted oxobicyclo-4,4,0-decane derivatives of our invention and, if desired, one or more of the above indicated additional flavoring additives may be added to the smoking tobacco material, to the filter or to the leaf or paper wrapper. The smoking tobacco material may be shredded, cured, cased and blended tobacco material or reconstituted tobacco material or tobacco substitutes (e.g., lettuce leaves) or mixtures thereof. The proportions of flavoring additives may be varied in accordance with taste but insofar as enhancement or the imparting of natural and/or sweet notes and/or cooling notes and/or fruity notes and/or woody notes, we have found that satisfactory results are obtained if the proportion by weight of the sum total of methyl substituted oxobicyclo-4,4,0-decane derivative(s) to smoking tobacco material is between 50 ppm and 1,500 ppm (0.015%-0.15%). We have further found that satisfactory results are obtained if the proportion by weight of the sum total of methyl substituted oxobicyclo-4,4,0-decane derivative used to flavoring material is between 1,500 and 15,000 ppm (0.15%-1.5%). 
     Any convenient method for incorporating the methyl substituted oxobicyclo-4,4,0-decane derivative(s) into the tobacco product may be employed. Thus, the methyl substituted oxobicyclo-4,4,0-decane derivative(s) taken alone or along with other flavoring additives may be dissolved in a suitable solvent such as ethanol, diethyl ether and/or volative organic solvents and the resulting solution may either be spread on the cured, cased and blended tobacco material or the tobacco material may be dipped into such solution. Under certain circumstances, a solution of the methyl substituted oxobicyclo-4,4,0-decane derivative(s) taken alone or taken further together with other flavoring additives as set forth above, may be applied by means of a suitable applicator such as a brush or roller on the paper or leaf wrapper for the smoking product, or it may be applied to the filter by either spraying, or dipping, or coating. 
     Furthermore, it will be apparent that only a portion of the tobacco or substitute therefor need be treated and the thus treated tobacco may be blended with other tobaccos before the ultimate tobacco product is formed. In such cases, the tobacco treated may have the methyl substituted oxobicyclo-4,4,0-decane derivative(s) in excess of the amounts or concentrations above indicated so that when blended with other tobaccos, the final product will have the percentage within the indicated range. 
     In accordance with one specific example of our invention, an aged, cured and shredded domestic burley tobacco is sprayed with a 20% ethyl alcohol solution of 3,4,4A,5,8,8A-hexahydro-2,2,5,8A-tetramethyl-1-(2H)-naphthalenone prepared according to Example VI(B), in an amount to provide a tobacco composition containing 800 ppm by weight of 3,4,4A5,8,8A-hexahydro-2,2,5,8A-tetramethyl-1-(2H)-naphthalenone on a dry basis. Thereafter, the alcohol is removed by evaporation and the tobacco is manufactured into cigarettes by the usual techniques. The cigarette when treated as indicated has a desired and pleasing aroma which is detectable in the main and sidestreams when the cigarette is smoked. This aroma is described as being sweeter, more aromatic, more tobacco-like and having a sweet, fruity note. 
     While our invention is particularly useful in the manufacture of smoking tobacco, such as cigarette tobacco, cigar tobacco and pipe tobacco, other tobacco products, formed from sheeted tobacco dust or fines may also be used. Likewise, the methyl substituted oxobicyclo-4,4,0-decane derivative(s) of our invention can be incorporated with materials such as filter tip materials (e.g. cellulose acetate filters wherein sweet, woody, fruity, floral and/or cooling effects are desired), seam paste, packaging materials and the like which are used along with tobacco to form a product adapted for smoking. Furthermore, the methyl substituted oxobicyclo-4,4,0-decane derivative(s) can be added to certain tobacco substitutes of natural or synthetic origin (e.g., dried lettuce leaves) and, accordingly, by the term &#34;tobacco&#34; as used throughout this specification is meant any composition intended for human consumption by smoking or otherwise, whether composed of tobacco plant parts or substitute materials or both. 
     The methyl substituted oxobicyclo-4,4,0-decane derivative(s) and one or more auxiliary perfume ingredients, including, for example, hydrocarbons, alcohols, ketones, aldehydes, nitriles, esters, lactones or cyclic esters, synthetic essential oils and natural essential oils, may be admixed so that the combined odors of the individual components produce a pleasant and desired fragrance, particularly and preferably in sandalwoody and/or patchouli-like fragrances. Such perfume compositions usually contain (a) the main note or the &#34;bouquet&#34; 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) top-notes which are usually low boiling fresh smelling materials. 
     In perfume compositions, it is the individual components which contribute to their particular olfactory characteristics, however the over-all sensory effect of the perfume composition will be at least the sum total of the effects of each of the ingredients. Thus, one or more of the methyl substituted oxobicyclo-4,4,0-decane derivative(s) 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. 
     The amount of methyl substituted oxobicyclo-4,4,0-decane derivative(s) of our invention which will be effective in perfume compositions as well as in perfumed articles and colognes depends on 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 methyl substituted oxobicylo-4,4,0-decane derivative(s) or even less (e.g. 0.005%) can be used to impart a minty, camphoraceous, dry, woody, sweet, fruity, patchouli-like, woody patchouli, green, herbaceous, basil-like, citrus-like, bergamot-like, lime-like, grapefruit-like, peppery, precious woody, vertiver-like, fresh, musky, lavander, thyme, rosemary, sweaty, rooty and earthy nuances with floral, citrus, lavander and amber topnotes to soaps, cosmetics, detergents (including anionic, non-ionic, cationic and zwitter-ionic solid or liquid detergents) or other products. The amount employed can range up to 70% 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 methyl substituted oxobicyclo-4,4,0-decane derivative(s) of our invention are useful (taken alone or together with other ingredients in perfume compositions) in detergents and soaps, space odorants and deodorants, perfumes, colognes, toilet water, hair preparations, such as lacquers, brilliantines, pomades and shampoos; cosmetic preparations, such as, creams, deodorants, hand lotions and sun screens; powders, such as talcs, dusting powders, face powders and the like. As little as 0.1% of the methyl substituted oxobicyclo-4,4,0-decane derivative(s) will suffice to impart an intense minty, camphoraceous, dry woody, sweet fruity, patchouli, woody patchouli, green, herbaceous, basil-like, citrus-like, bergamot-like, lime-like, graperfruit-like, peppery, precious woody, vertiver-like, fresh, musky, lavander, thyme, rosemary, sweaty, rooty and/or earthy aroma to woody perfume formulations. Generally, no more than 5% of the methyl substituted oxobicyclo-4,4,0-decane derivative(s) based on the ultimate end product, is required in the perfume composition. 
     In addition, the perfume composition or fragrance composition of our invention can contain a vehicle, or carrier for the methyl substituted oxobicyclo-4,4,0-decane derivative(s). The vehicle can be a liquid such as a non-toxic alcohol, a non-toxic glycol, or the like. The carrier can also be an absorbent solid, such as gum (e.g., gum arabic), or components for encapsulating the composition (such as gelatin). 
     It will thus be apparent that the methyl substituted oxobicyclo-4,4,0-decane dervative(s) of our invention can be utilized to alter, modify or enhance sensory properties, particularly organoleptic properties, such as flavor(s) and/or fragrance(s) of a wide variety of consumable materials. 
     The following Examples serve to illustrate processes for specifically producing the methyl substituted oxobicyclo-4,4,0-decane derivatives of our invention and also serve to illustrate specific embodiments of our invention. 
     It will be understood that these Examples are illustrative and the invention is to be considered restricted thereto only as indicated in the appended claims. 
     All parts and percentages given herein are by weight unless otherwise specified.

     Into a 2000 cc reaction flask equipped with stirrer, condenser, thermometer and dropping funnel is placed 680 cc (2.04 moles) of methylmagnesium chloride (3 M) in a tetrahydrofuran solution. Dropwise allowing a slow exotherm, 170 g (0.82 moles) of the mixture of ketones having the structures: ##STR233## prepared according to Example IV, is added to the reaction mass. After addition, the reaction mass is refluxed for 16 hours while being monitored by GLC analysis in order to ascertain completion. 
     The reaction mass is then hydrolyzed with 200 cc of saturated ammonium chloride solution. The resulting hydrolyzed material is then extracted with two 100 cc portions of toluene. The toluene extract is stripped of toluene and distilled to yield the following fractions:

     The foregoing flavor formulation is divided into two parts. To the first part at the rate of 5% is added the methyl substituted oxobicyclo-4,4,0-decane derivative prepared according to either of Example XII or XIII. To the second part, nothing is added. Both flavors are compared by a bench panel at the rate of 20 ppm in water. The flavor with the addition of the product produced according to each of Examples XII and XIII have pleasant fresh walnut kernel taste with fresh walnut aromas not present in the basic walnut flavor formulation. Therefore, the flavors with the materials produced according to both Examples XII and SIIII are preferred as being much more characteristic in the walnut flavor by the bench panel (unanimous preference). The flavor is also evaluated at 1 ppm and the same unaminous preference is obtained.

     EXAMPLE XXVII 
     Preparation of a Soap Composition 
     One hundred grams of soap chips are produced according to Example V of U.S. Pat. No. 4,058,487 issued on Nov. 15, 1977, as follows: 
     &#34;The sodium salt of an equal mixture of C 10  -C 14  alkane sulfonate (95% active), 40 pounds, is dissolved in a mixture of 80 pounds of anhydrous isopropanol and 125 pounds of deionized water at 150° F. In this mixture is dissolved 10 pounds of partially hydrogenated cocoanut oil fatty acids and 15 pounds of sodium mono-C 14  alkyl maleate, and the pH of this solution is adjusted to 6.0 by the addition of a small amount of 50% aqueous solution of sodium hydroxide. The isopropanol is distilled off, and the remaining aqueous solution is drum dried. The resulting solid actives are then blended in a chip mixture with 10 pounds water, 0.2 pounds titanium hydroxide and 0.7 pounds of one of the materials produced according to Examples I-XVI as enumerated in the Table below. The chips are then plodded into logs, cut to size and finally stamped into bars having a pH of approximately 6.9.&#34; 
     Each of the perfumed soaps manifests aromas with strong patchouli notes as indicated in the Table VIII below:

     EXAMPLE XXIX 
     Tobacco Filter 
     Into a 20 mm cellulose acetate filter is added the mixture of ketones having the structures: ##STR423## prepared according to Example VIA at the rate of 1000 ppm (10 micro liters of a 10% solution of said ketones are added to the filter). The filter is then attached to a full flavor cigarette on the market, e.g. (1) Marlboro®, (2) Winston® or (3) Viceroy®, as well as on a Kentucky 1A3 reference cigarette (produced by the University of Kentucky) yielding the following results: 
    
     1. Both cigarettes containing the ketone mixture additive, when compared to a cigarette having a filter without said ketone mixture additive, gives rise to a sweet, fruity, woody, cooling, floral and berry-like aroma on smoking with a pleasant cooling effect and rather noticeable reduced harshness. 
     2. Both cigarettes containing said ketone mixture additive, have a lesser degree of &#34;hotness&#34; and give rise to a &#34;fresh&#34; taste on smoking.

     To portions of 50% of the cigarettes at levels of 10 and 20 ppm, methyl substituted oxobicyclo-4,4,0-decane derivatives as indicated in Table X below are added. These cigarettes are hereinafter called &#34;experimental&#34; cigarettes and the cigarettes without the methyl substituted oxobicyclo-4,4,0-decane derivatives as set forth in Table X below, are hereinafter called &#34;control&#34; cigarettes. The &#34;control&#34; and &#34;experimental&#34; cigarettes are then evaluated by paired comparison and the results are as follows: 
     a. In aroma, the &#34;experimental&#34; cigarettes are all found to be more aromatic with nuances as indicated in Table X below; 
     b. In smoke flavor, the &#34;experimental&#34; cigarettes are found to be more aromatic, more sweet with bitter, richer and less harsh nuances on smoking in both the mainstream and the sidestream than the &#34;control&#34; cigarettes. 
     The &#34;experimental&#34; cigarettes containing 20 ppm of each of the compounds which are methyl substituted oxobicyclo-4,4,0-decane derivatives prepared according to the examples in the instant case and set forth in Table X below are found to be superior in flavor than those not containing such compounds:

     The Cab-O-Sil is dispersed in the liquid sweet anise flavor compositions of Example XXV with vigorous stirring, thereby resulting in a viscous liquid. 71 Parts by weight of the powder flavor composition of Part A, supra, is then blended into the said viscous liquid, with stirring, at 25° C. for a period of 30 minutes resulting in a dry, free flowing sustained release flavor powder. 
     EXAMPLE XXXII 
     10 Parts by weight of 50 Bloom pigskin gelatin is added to 90 parts by weight of water at a temperature of 150° F. The mixture is agitated until the gelatin is completely dissolved and the solution is cooled to 120° F. 20 Parts by weight of the liquid flavor composition of Example XXV is added to the solution which is then homogenized to form an emulsion having particle size tyically in the range of 2-5 microns. This material is kept at 120° F. under which conditions the gelatin will not jell. 
     Coascervation is induced by adding, slowly and uniformly 40 parts of a 20% aqueous solution of sodium sulphate. During coascervation the gelatin molecules are deposited uniformly about each oil droplet as a nucleus. 
     Gelation is effected by pouring the heated coascervate mixture into 1,000 parts by weight of 7% aqueous solution of sodium sulphate at 65° F. The resulting jelled coascervate may be filtered and washed at temperatures below the melting point of gelatin, to remove the salt. 
     Hardening of the filtered cake, in this example, is effected by washing with 200 parts by weight of 37% solution of formaldehyde in water. The cake is then washed to remove residual formaldehyde. 
     EXAMPLE XXXIII 
     Chewing Gum 
     100 Parts by weight of chicle are mixed with 4 parts by weight of the flavor prepared in accordance with Example XXIX. 300 Parts of sucrose and 100 parts of corn syrup are added. Mixing is effected in a ribbon blender with jacketed side walls of the type manufactured by the Baker Perkins Co. 
     The resultant chewing gum blend is then manufactured into strips 1 inch in width and 0.1 inches in thickness. The strips are cut into lengths of 3 inches each. On chewing, the chewing gum has a pleasant, long lasting walnut flavor. 
     EXAMPLE XXXIV 
     Chewing Gum 
     100 Parts by weight of chicle are mixed with 18 parts by weight of the flavor prepared in accordance with Example XXXII. 300 Parts of sucrose and 100 parts of corn syrup are then added. Mixing is effected in a ribbon blender with jacketed side walls of the type manufactured by the Baker Perkins Co. 
     The resultant chewing gum blend is then manufactured into strips 1 inch in width and 0.1 inches in thickness. The strips are cut into lengths of 3 inches each. On chewing, the chewing gum has a pleasant, long lasting walnut flavor.
