Propanol derivatives and perfumes containing the same
This is a Continuation of Application No. 07/592,099 filed Oct. 3, 1990 abandoned. 
    
    
     FIELD OF THE INVENTION 
     This invention relates to a novel propanol derivative useful for perfume cosmetics, etc., and a perfume containing the same as an active ingredient. 
     BACKGROUND OF THE INVENTION 
     Some naturally-occurring compounds exhibit various characteristics attributed to their asymmetric structure. Of physiologically active substances having an asymmetric structure, many of those useful for humans are confined to the respective specific antipode. This tendency is particularly conspicuous in the field of pharmaceuticals, agricultural chemicals, pheromones, and food additives. It is known in these fields that a racemic mixture may have a markedly reduced effect or rather exhibit a counter effect. The field of perfumes is no exception to this tendency. For example, l-menthol has the odor of mint; d-carvone has the odor of Caraway L.; and d-nootkatone has the odor of grapefruit. Each of these optical antipodes is different from or stronger than the respective other optical antipodes in odor. The latest examples of such a phenomenon are observed in α-ionone, hydroxycitronellal, and rose oxide. For the detail, reference can be made to Kaqaku Sosetsu, No. 14, Ch. 6 &#34;Aji to Nioi no Kagaku&#34;(1976). 
     Therefore, development of optically active perfume components as well as development of novel perfumes would lead to development of optical antipodes having a new odor or usefulness and are of industrial significance. 
     With respect to 3-(2,2,6-trimethylcyclohexan-1-yl)-propanol derivatives, compounds known to have a wood-like fragrance or an amber-like fragrance include 1-(2,2,6-trimethylcyclohexan-1-yl)pentan-3-ol having an ethyl group as the alkyl moiety (see West German Patent Application (OLS) No. 2,455,761), 1-(2,2,6-trimethylcyclohexan-1-yl)hexan-3-ol having a propyl group as the alkyl moiety (see JP-A-62-70314, JP-B-1-38438, JP-B-59-18373, JP-A-61-191636, and JP-B-62-16935; the terms &#34;JP-A&#34; and &#34;JP-B&#34; as used herein mean an &#34;unexamined published Japanese patent application&#34; and an &#34;examined Japanese patent publication&#34;, respectively), and 5-methyl-1-(2,2,6-trimethylcyclohexan-1-yl)hexan-3-ol having an isobutyl group as the alkyl moiety (see USSR Patent 1,082,780). 
     JP-B-1-38438 discloses a composition of 1-(2,2,6-trimethylcyclohexan-1-yl)hexan-3-ol comprising 80% or more of a trans isomer and not more than 20% of a cis isomer. 
     Since these cis and trans isomers each has an asymmetric carbon atom in the molecule thereof, it is expected that there are a pair of enantiomers, i.e., (+)-isomer and (-)-isomer. However, the compounds disclosed in the above-cited references exist as a racemic mixture. No other study has been reported on synthesis or properties of the individual optical isomers. 
     The recent diversity of cosmetics and sanitary goods has created a new increasing demand for a perfume material which has high diffusibility, unique scent, high tastiness, high retention, satisfactory stability, and high safety. In particular, perfume materials having an amber-like fragrance and satisfying these requirements have been wanted. 
     SUMMARY OF THE INVENTION 
     Accordingly, an object of this invention is to provide an optically active compound which is capable of imparting an amber-like fragrance while meeting the above-described demand. 
     Another object of this invention is to provide a perfume comprising the above-described optically active compound as an active ingredient. 
     In the light of the above-mentioned circumstances, the inventors have conducted extensive investigations and, as a result, succeeded to synthesize an optically active isomer of a 3-(2,2,6-trimethylcyclohexan-1-yl)propanol derivative and found that the 6(S)-isomer of the compound has a sharp and highly diffusible amber fragrance free from a wood-like fragrance accompanied by the dim odor of mold and is useful as a perfume. The present invention has been completed based on this finding. 
     The present invention relates to an optically active 3-[6(S)-2,2,6-trimethylcyclohexan-1-yl]propanol derivative represented by formula (I): ##STR2## wherein R 1  represents a lower alkyl group. 
     The present invention further relates to a perfume containing the optically active compound of formula (I) as an active ingredient. 
     DETAILED DESCRIPTION OF THE INVENTION 
     In formula (I), the lower alkyl group as represented by R 1  preferably contains from 1 to 4 carbon atoms, and specific examples thereof include a methyl group, and ethyl group, an n-propyl group, an isopropyl group, an n-butyl group, and an isobutyl group. 
     The optically active 3-[6(S)-2,2,6-trimethylcyclohexan-1-yl]propanol derivative of formula (I) can be synthesized, for example, in the following reaction scheme. ##STR3## wherein R 1  is as defined above; and X represents a halogen atom. 
     That is, the optically active 3-[6(S)-2,2,6-trimethylcyclohexan-1-yl]propanol derivative of formula (I) can easily be synthesized by reacting an optically active 3-[6(S)-2,2,6-trimethylcyclohexan-1-yl]propanal represented by formula (2) with an alkylmagnesium halide represented by the formula, R 1  MgX, wherein R 1  and X are the same as defined above. 
     The starting compound, 3-[6(S)-2,2,6-trimethylcyclohexan-1-yl]propanal (2), is a novel compound and can be synthesized in the following reaction scheme: ##STR4## wherein R 2  represents a hydrogen atom or a methyl group; Ac represents an acetyl group; Et represents an ethyl group; and the wavy line indicates a trans- and/or cis-position. 
     While an optically active 1-[6(S)-2,2,6-trimethylcyclohexan]carbaldehyde (5) as an intermediate compound of the above reaction route is known to be synthesized by starting with optically active citronellal as described in JP-A-63-44544, it can easily be synthesized in a high yield by starting with optically active l-methoxycitronellal (3) which is used on an industrial scale as a perfume or juvenile pheromone of mosquito larvae. Namely, l-methoxycitronellal (3) is reacted with acetic anhydride to obtain an enol acetate (4) which, as produced, is then subjected to cyclization in the presence of a phosphoric acid catalyst to obtain the compound (5). 
     The compound (5) is then reacted with triethyl phosphonoacetate (6) by utilizing the Wittig reaction described, e.g., in Herbert 0. House, Modern Synthetic Reaction, p. 690, W. A. Benjamin, Inc., Menlo Park, Calif., U.S.A. (1972) to synthesize optically active ethyl 3-[6(S)-2,2,6-trimethylcyclohexan-1-yl]acrylate (7). 
     The compound (7) is reduced by using sodium borohydride or sodium bis(2-methoxyethoxy)aluminum hydride to synthesize optically active 3-[6(S)-2,2,6-trimethylcyclohexan-1-yl]-2-propen-1-ol (8) which is then oxidized with manganese dioxide to obtain optically active 3-[6(S)-2,2,6-trimethylcyclohexan-1-yl]-2-propen-1-al (9). The compound (9) is then hydrogenated in the presence of a palladium-on-carbon as a catalyst to synthesize optically active 3-[6(S)-2,2,6-trimethylcyclohexan-1-yl]propanal (2). 
     While the above description relates to synthesis of the 6(S)-compound, a 6(R)-compound can be obtained in the similar manner by starting with d-methoxycitronellal in place of l-methoxycitronellal. 
     It surprisingly turned out that the scent given off by the thus obtained 3-[2,2,6-trimethylcyclohexan-1-yl]propanol derivatives utterly differs between different optical antipodes. More specifically, the 6(S)-compounds have a sharp amber fragrance with very high diffusibility in common, though somewhat different in strength and quality depending on the kind of R 1 . On the other hand, the 6(R)-compounds basically produce no amber fragrance and give off a powerless wood-like fragrance with a little moldiness. The racemates give off a dull woody amber fragrance which is remarkably different from and far less powerful than that of the 6(S)-compounds. 
     Further, each of the 6(S)-compounds differing in R 1  was proved effective to impart to a perfume composition a distinct top note to yield a fresher and tastier composition as though it is of different kind from the corresponding 6(R)-compound or racemate. It was also proved that the 6(S)-compounds have high fragrance retention and high masking effects over odors of bases of soaps, etc., odors of bleaching agents, and ozone odor and are, therefore, very useful as perfume materials. 
     Thus, there is provided a fresh and tasty fragrance or a fragrance modifying or strengthening agent with high diffusibility and retention, which contains the 3-[6(S)-2,2,6-trimethylcyclohexan-1-yl]propanol derivative according to the present invention. There are also provided cosmetics, sanitary goods, pharmaceuticals, etc., which contain the compound of the invention as a perfume component. That is, the compound according to the present invention can be incorporated in an amount effective to impart its unique fragrance into bases of hair care cosmetics, e.g., shampoos, rinses, perfumes, colognes, hair tonics, hair creams, pomades, etc.; bases of facial cosmetics, e.g., face powders, lip sticks, etc.; toilet goods, e.g., face cleansers, soaps, disinfectants, tooth pastes, mouth-washes, toilet paper, etc.; various detergents, e.g., dish washing detergents, laundry detergents, textile softeners, disinfectant detergents, deodorant detergents, bleaching agents, etc.; environmental aromatizers, furniture care goods, insecticides; flavors for facilitating administration of medicines; and the like thereby to enhance the commercial value of these goods. 
     A suitable amount of the propanol derivative according to the present invention which is used in a perfume composition to be applied to various products is from 0.0001 to 50% by weight and preferably from 0.001 to 20% by weight. 
     The present invention is now illustrated in greater detail with reference to Synthesis Examples and Examples. All the parts, percents, and ratios are by weight unless otherwise indicated.

     In a 5 l-volume four-necked flask equipped with a condenser, a thermometer, a dropping funnel, and a stirrer were charged 871 g of acetic anhydride, 27 g of sodium acetate, and 706 g of triethylamine under a nitrogen atmosphere, and the mixture was heated to 75° C. while stirring. To the resulting solution was added dropwise 1 kg of l-methoxycitronellal (a commercially available product of Takasago International Corporation; [α] D   25  : -10.42°; optical purity: 98% ee) over 1 hour. 
     After the dropwise addition, the reaction mixture was refluxed at 101° to 117° C. for 6-hours, followed by cooling to 5° C. To the reaction mixture were added 500 g of water and 500 g of toluene to conduct water washing and liquid-liquid separation. Again, 500 g of water was added thereto to conduct water washing and liquid-liquid separation to obtain 1,690 g of a toluene solution of an enol acetate (4). Gas chromatography (&#34;HEWLETT PACKARD 5890&#34;; column: Carbowax 20M (HP); 0.2 mm ID ×25 m) (hereinafter abbreviated as GC) revealed that the solute was composed of 29.5% of cis-compound (4), 62.7% of trans-compound (4), and 5.3% of diacetate (10). ##STR5## wherein Me represents a methyl group; and Ac represents an acetyl group.

     In a 300 ml-volume four-necked flask equipped with a condenser, a thermometer, a dropping funnel, and a stirrer were charged 5.0 g of a magnesium powder, 0.001 g of iodine, 0.5 g of n-propyl iodide, and 10 ml of tetrahydrofuran under a nitrogen atmosphere. After confirming the start of a Grignard reaction (bubbling and heat evolution), 100 ml of tetrahydrofuran was added to the reaction mixture, and 18 g of n-propyl chloride was added dropwise thereto at 35° to 40° C. over hours, followed by stirring at that temperature until the magnesium powder disappeared, to prepare a tetrahydrofuran solution of n-propylmagnesium chloride. To the resulting solution was added dropwise a solution of 15 g of the 3-[6(S)-2,2,6-trimethylcyclohexan-1-yl]propanal (2) obtained in Synthesis Example 5 in 15 ml of tetrahydrofuran at 5° C. over 2 hours, followed by stirring at that temperature for 4 hours to complete the reaction.

     EXAMPLE 2 
     Masking Test of Amino Acid Shampoo 
     In order to test masking effect on the odor of the base of an amino acid shampoo, a shampoo composition containing 1-[6(S)-2,2,6-trimethylcyclohexan-1-yl]heptane-3-ol or a racemate thereof as shown in Table 3 below was prepared, and the degree of masking was evaluated by a panel of 5 specialists. As a result, the panel judged that Composition A containing the optically active compound smelled pleasantly of amber with the base odor being perfectly masked; Composition B containing the racemate smelled considerably of the base; and the smell of the base was substantially overpowered in Composition C containing the racemate in an amount 8 times that of the optically active compound in Composition A.

     Musk Base 
     A musk base having the following formulation was prepared, and the 1-[6(S)-2,2,6-trimethylcyclohexan-1-yl]-5-methylhexan-3-ol as synthesized in Synthesis Example 17 or a racemate thereof [mixture of 6.S()/6(R) =1/1]was compounded therein as shown in Table 4 below. Odor evaluation on the resulting perfumes (B-1, B-2, B-3, and B-4) was carried out by a panel of 5 specialists based on the following rating standards. The results are shown in Table 4. As a result of the fragrance test, the panel judged that: B-1 containing the optically active compound and B-4 containing the racemate in an amount 9 times that of the optically active compound in B-1 had an almost equal strength of fragrance, the top note of B-4  being, however, broadwise spreading and lacking sharpness, while B-1 had a well-balanced fragrance with freshness and was preferred to B-4. With respect to B-2, B-3, and B-4, the panel judged that the strength of fragrance was decreasing in the order of B-4&gt;B-3&gt;B-2 and that the preference was also decreasing in the same order.

     Test of preference was carried out on each of Compositions (A) and (B) by a panel of 5 specialists. As a result, the panel judged that Composition (A) containing the optically active compound was better than Composition (B) because of diffusibility, freshness, and harmony of the fragrance. Further, towels were washed using each of Compositions (A) and (B), and the scent remaining on the laundry was tested by the panel. As a result, the panel judged that the towels washed by using Composition (A) had a stronger and better-balanced scent and were thus preferred.

     1-[6(S)-2,2,6-Trimethylcyclohexan-1-yl]-pentan-3-ol or a racemate thereof was added to the liquid hypochlorite bleaching solution in an amount of 0.1% or 0.2%, respectively to prepare Composition (A) or (B) having an amber fragrance. 
     The degree of masking of the odor of the hypochlorite in each of Compositions (A) and (B) was tested by a panel of 5 specialists. As a result, the panel judged that Composition (A) had a fresh amber-like fragrance with no perceptible odor of the hypochlorite, whereas Composition (B) smelled slightly of the hypochlorite. 
     Further, towels were washed in a washing machine using each of Compositions (A) and (B) as a bleaching agent, and the scent remaining on the laundry was tested by a panel of 5 specialists. As a result, the panel judged that the towels washed by using Composition (A) containing the optically active compound had a pleasant and fresh amber fragrance with no perceptible odor of the hypochlorite, whereas those washed by using Composition (B) containing the racemate smelled slightly of the hypochlorite. Incidentally, the towels washed by using Composition (A) proved bleached (whitened) to the same degree as those washed by using a bleaching agent having the same composition except for the perfume component. 
     The present invention provides an industrially useful optically active 3-[6(S)-2,2,6-trimethylcyclohexan-1-yl]-propanol derivative and a perfume containing the same as an active ingredient. The optically active 3-[6(S)-2,2,6-tri-methylcyclohexan-1-yl]propanol derivative has excellent properties as a perfume, and the perfume containing the same as an active ingredient is useful in broad fields, such as various cosmetics, sanitary goods, pharmaceuticals, etc. 
     While the invention has been described in detail and with reference to specific embodiments thereof, it will be apparent to one skilled in the art that various changes and modifications can be made therein without departing from the spirit and scope thereof.
