     FIELD OF THE INVENTION 
     The present invention relates to compounds useful as fragrance or flavor components in fragrance or flavor compositions. 
     BACKGROUND OF THE INVENTION 
     The fragrance industry is constantly reliant on the development of new chemicals with favorable organoleptic properties to provide perfumers and other persons the capability of creating new, unique fragrances for applications such as personal care products, air care products, perfumes, colognes and the like. 
     3-methoxy-3-methyl-1-butanol, also known as Solfit™, is known in the perfume industry and has been applied in many consumer products (WO 9512379; JP 2001226246; JP 2005290236; JP 001104462). The structure of 3-methoxy-3-methyl-1-butanol is shown below: 
     
       
                 
         
             
             
         
      
     
     Some esters derived from this alcohol have been employed as solvents for consumer products (EP 462605A2). Ether analogues of this alcohol have been used as intermediates to useful homoallylic alcohol entities (U.S. Pat. No. 4,990,697).

     In one aspect, the present invention provides a method to modify, enhance or improve olfactory and/or organoleptic property (e.g odor or flavor property) of a fragrance or flavor composition by adding to said composition an olfactory or organoleptic effective quantity of the compound of formulas (I-VI). In one embodiment, a fragrance compound is added to a fragrance carrier, fragrance base or both to provide a fragrance composition. In an alternative embodiment, a flavor compound is added to a flavor carrier to provide a flavor composition. It is understood here also that the invention may be described as the use of any composition containing formulas (I-VI) in fragrance and/or flavor compositions. 
    
    
     DETAILED DESCRIPTION OF THE INVENTION 
     Fragrance Compositions 
     The present invention is directed to the use of the above compounds as fragrances in a fragrance composition. The compounds can be incorporated alone, as a mixture of two or more of said compounds, or as an enhancer to an existing fragrance composition (discussed below). These compounds add a favorable olfactory effect to the desired product. The compounds are typically present in an amount of from about 0.001 to about 30.0 by weight of the total fragrance composition. Typically a more preferred embodiment would contain between 0.01% and 20% by weight and a most preferred embodiment would contain between 0.01% and 10% by weight. None of these examples shown are meant to be limiting or restrictive on the use of the material as stated. 
     One embodiment of the present inventions provides a method to modify, enhance or improve the odor properties of a fragrance composition by adding to said composition an olfactory effective quantity of the compound of formulas (I-VI). The invention may also be described as the use of any composition containing compound (I-VI) which can be advantageously employed in the fragrance industry as active ingredients. 
     Such compositions may contain or consist of at least one ingredient selected from a group consisting of a fragrance carrier and a fragrance base. Such compositions may also consist of at least one fragrance adjuvant. 
     Said fragrance carriers may be a liquid or a solid and typically do not significantly alter the olfactory properties of the fragrance ingredients. Some non-limiting examples of fragrance carriers include an emulsifying system, encapsulating materials, natural or modified starches, polymers, gums, pectins, gelatinous or porous cellular materials, waxes, and solvents which are typically employed in fragrance applications. 
     Said fragrance base refers to any composition comprising at least one fragrance co-ingredient. In general, these co-ingredients belong to chemical classes such as, but not limited to: alcohols, aldehydes, ketones, esters, ethers, acetals, oximes, acetates, nitriles, terpenes, saturated and unsaturated hydrocarbons and essential oils of natural or synthetic origins. 
     Table 2 provides an example of a formulated fragrance in which compounds of the present invention can be added.

     As used herein, olfactory effective quantity will be defined as the amount of said compound in a fragrance composition in which the individual component will contribute its characteristic olfactory properties, for example an olfactory property found to be more hedonistically appealing. A person of ordinary skill in the art may optimize the olfactory effect of the fragrance composition based on the incorporation of a fragrance compound of the present invention. The fragrance compounds may be used individually, or a part of mixture such that the sum of the effects of all fragrance ingredients present in the mixture yields a higher hedonistic rating. Therefore, the compounds embodied in the present invention can be employed to modify the characteristics of existing fragrance composition via their own olfactory properties or through additively effecting the contributions of other ingredient(s) present within the said composition. The quantity will vary widely depending on the other ingredients present, their relative amounts, the desired effect and the nature of the product. 
     Flavor Composition 
     Compounds of formulas (I-VI) can be employed alone or incorporated into mixtures to enhance already existing flavor compositions. These compounds add a favorable organoleptic property and effect to the desired product. The compounds are typically present in an amount of from about 0.01% to about 20.0% by weight of the total flavor composition. Typically a more preferred embodiment would contain between 0.01% and 10% by weight and a most preferred embodiment would contain between 0.01% and 5% by weight. None of these examples shown are meant to be limiting or restrictive on the use of the material as stated. 
     As used herein, organoleptic effective quantity will be defined as the amount of said compound in a flavor composition in which the individual component will contribute its characteristic flavor properties. However, the organoleptic effect of the flavor composition will be the sum of the effects of all flavor ingredients present. Therefore, the compounds embodied in the present invention can be employed to modify the characteristics of the flavor composition via their own organoleptic properties or through additively effecting the contributions of other ingredient(s) present within the said composition. The quantity will vary widely depending on the presence of other ingredients present, their relative amounts, the desired effect and the nature of the product. 
     The flavor carrier may be a liquid or a solid and typically do not significantly alter the olfactory or organoleptic properties of the flavor ingredients, respectively. Some non-limiting examples of flavor carriers include an emulsifying system, encapsulating materials, natural or modified starches, polymers, pectins, proteins, polysaccharides, gums and solvents which are typically employed in flavor applications. 
     As used herein, the term “flavor carrier” may also encompass the food or beverage to which the fragrance compound (i.e. compounds encompassed by formulas I-VI) are added. Examples of such foods or beverages include, but are not limited to carbonated fruit beverages, carbonated cola drinks, wine coolers, cordials, flavored water, powders for drinks (e.g., powdered sports or “hydrating” drinks), hard candy, soft candy, taffy, chocolates, sugarless candies, chewing gum, bubble gum, condiments, spices and seasonings, dry cereal, oatmeal, granola bars, soups, alcoholic beverages, energy beverages, juices, teas, coffees, salsa, gel beads, film strips for halitosis, gelatin candies, pectin candies, starch candies, lozenges, cough drops, throat lozenges, throat sprays, toothpastes and mouth rinses.

     Synthesis Details 
     Compounds of formula I may be isolated from the reaction of 3-methoxy-3-methyl-1-butoxide with an alkyl halide. Similarly, reaction of this alkoxide with an allyl halide results in a compound of formula (I) as well. Table 1 lists the olfactory properties of various novel compounds synthesized in accordance to formula (I). In particular, the unsaturated 3-methoxy-3-methyl-1-butanol ether derivatives described in the present invention all contain citrus and/or green notes incorporated into their odor compositions. Saturation of these olefinic substituents via hydrogenation results in a woody, fruitier olfactory character. 
     Compounds encompassed by formula II can be synthesized via simple condensation reactions between the alcohol, 3-methoxy-3-methyl-1-butanol, and the respective carboxylic acid. Alternatively, compounds of formula (II) can be synthesized by direct reaction of the alcohol with the respective acid chloride. Table 1 lists the odor characteristics of various novel compounds synthesized in accordance to formula (II). 
     The syntheses of all compounds related to formula (II) proceed with high yields. As represented in Table 1, the majority of the alkyl 3-methoxy-3-methyl-1-butanol esters have a strong fruity note associated with them. 
     Compounds of formula III may be isolated from the reaction of 3-methoxy-3-methyl-1-butanol (Solfit™) with an alkyl chloroformate. The synthesis proceeds in a straight forward, facile manner. Table 1 lists the olfactory properties of various novel compounds synthesized in accordance to formula (III). The fragrance compounds encompassed by formula III generally maintain a light and soft quality. 
     The syntheses of compounds (glycolates) encompassed by formula (IV) proceeded smoothly and in high yield. Simple esterification of various alkoxy carboxylic acids with 3-methoxy-3-methyl-1-butanol in the presence of a catalytic amount of acid resulted in the desired products. Glycolates of this nature have a consistent light, powdery musk property. The musk qualities associated with these chemical entities have been reported in other glycolate-type compounds (See, e.g., U.S. Published Application No. 2006/0052277, which is hereby incorporated by reference). 
     The present inventors have found that glycolates encompassed by formula (V) can be isolated in high yields when the reaction specifically employs 2-(3-methoxy-3-methylbutoxy)acetic acid with a respective alcohol to undergo esterification in similar fashion to the syntheses of compounds of formula (IV). Alternatively, reactions involving an alkyl halo-acetate with 3-methoxy-3-methyl-1-butoxide result in a low yield of the desired glycolate due to a mixture of undesired side products. 
     The synthesis of the compound of formula (VI) in which n=0 and R 6 =hydrogen proceeded smoothly via its dimethyl acetal precursor. Cleavage of the acetal group under acidic conditions afforded the respective acetaldehyde. This compound can also be synthesized via ozonolysis of allyl 3-methoxy-3-methyl-1-butanol ether. Such an approach was taken for the compound of formula (VI) in which n=0 and R 6 =methyl. Both compounds possess odor characteristics which can be described as clean, melon-like and fresh with very strong diffusive properties. 
     The synthesis of compounds of formula (VI) in which n=1 and R 6 =hydrogen or a methyl group was based on a revised adaptation of previously reported syntheses between alcohols and α-β-unsaturated aldehydes (U.S. Pat. No. 2,694,733; Feldman, D. P.; Stonkus, V. V.; Shimanskaya, M. V.; Avots, A. A.  Russ. J. Gen. Chem.  1995, 65, 250-253). In the present case, acrolein and crotonaldehyde have been chosen as the α-β-unsaturated aldehydes. In each of the previously reported syntheses for reactions of this type, specific conditions involving the buffer capacity of the system were stressed. The syntheses reported here proceeded with extremely low yields (&lt;5%) when employing such conditions. The present inventors found that the presence of a catalytic amount of acid greatly promotes the formation of the desired aldehydes. As listed in Table 1, such aldehydes of this nature have a much more waxy, fatty-type aroma than the acetaldehyde analogues (n=0).

     A suspension of sodium hydride (11.8 g, 0.47 mol) in anhydrous THF (400 mL) was warmed to approximately 40° C. under an inert atmosphere. A portion of 3-methoxy-3-methyl-1-butanol (50.0 g, 0.42 mol) was then added dropwise via syringe over a period of 20 minutes during which time the temperature of the mixture was slowly raised to 70° C. at 5 degree intervals. After one hour, bromoacetaldehyde dimethyl acetal (54.0 mL, 0.46 mol) was added dropwise via syringe over a period of 30 minutes and the mixture was stirred vigorously at 70° C. for 16 hours. After this time, the mixture was cooled to room temperature, treated with H 2 O (200 mL) and extracted with diethyl ether (3×200 mL).

     A portion of 1-methoxy-1,1-dimethyl-3-(1-methyl prop-2-enyloxy)propane (5.75 g, 33.3 mmol) was dissolved in CH 2 Cl 2  (50 mL) and cooled to −78° C. The solution was purged with ozone for approximately one hour. Once the solution became blue, O 2  was bubbled through it for 30 minutes until the color disappeared and the reaction was quenched via addition of triphenylphosphine (10.5 g, 40.0 mmol). The solvent was removed via rotary evaporation and the resulting residue was suspend in a hexane:diethyl ether (1:1) mixture overnight in the refrigerator. The mixture was filtered and the precipitate was rinsed with hexane. The filtrate was placed on a rotary evaporator and the solvent was removed under reduced pressure. The isolated crude material was distilled via Kugelrohr apparatus (64° C., 0.40 torr) resulting in a colorless liquid (4.57 g, 78.8%). Odor: fresh, watery melon, clean, floral, muguet.

     Procedure:1. ⅓ of Seq.#1 and Seq.#2 was heated to 85° C. Methocel powder was by mixing thoroughly using ⅕ to ⅓ of the required total amount of water as hot water (80-90° C.). Mixing was continued with overhead mixer at medium speed until all of the particles were wetted down, and a consistent dispersion was obtained. The remainder of the water containing Seq. #2 was added as cold water while mixing. The solution was cooled down to less than 30° C. Mixing was continued after the proper temperature was achieved for approximately 20 minutes. After preparation was completed, the Methocel® solution was reheated to 60° C. 
     2. Seq.#4 at 60 to 65° C. was added slowly to the batch in order of addition with mixing continued at low speed. 
     3. Seq.#5 was added slowly to batch and mixing continued at low speed until room temperature was reached. Citric acid was added to a pH of 5.5-6.0 and sodium chloride was added to achieve the desired viscosity. Fragrance Seq.#6 was weighed and added to the formulation while mixing. 
     4. Viscosity: =2020 cps. (±10%) taken at 20° C., (Brookfield LV Sp.#3 @ 12 rpm), pH=5.5 (+/−0.5)
