DESCRIPTION METHOD OF PRODUCINGMACROCYCLIC KETONE, AND INTERMEDIATE THEREOF TECHNICAL FIELD The present invention relates to a method of producing a macrocyclic ketone muscone, in particular a method of producing muscone by 1,4-conjugation methyl-addition reaction of 2-cyclopentadecenone, and a new intermediate compound used in production thereof. BACKGROUND ART Recently the trend toward natural products of people has been rising, and in the field of the fragrance, there also arouses an interest for a musk-feeling fragrance having a higher aroma property and characteristically reminding of natural environment. Further, there is also a need for development of a new fragrance material derived from a natural compound or the same as or similar to a natural compound, from the point of safety for human beings and the environment. Muscone is the principal fragrance component in natural musk and contained in the amount of 0 . 5 to 2 . 0% therein. Muscone was found out by Walbaum in 1906, and its chemical structure was determined by Ruzicka in 1926. Natural muscone is (-) - (R) -3-methylcyclopentadecanone, but its commercial product is a synthetic dl-isomer. When the fragrance of (-) - (R)-isomer and (+)-(S)-isomer is compared, the (R)-isomer has a diffusive stronger musk-feeling fragrance (threshold value : 3 ppm) , while the (S)-isomer has a chemical, less-diffusive, poor and weak musk-feeling fragrance (threshold value: 10 ppm) , and thus, the intensity of the fragrance of the (R) -isomer is known to be thrice greater than that of the (S)-isomer (see, for example, Non-patent Document 1 and Non-patent Document 2 below). Non-patent Document 1: Indo Motoichi, "Synthetic Aromachemical - Chemistry and Commodity knowledge ", The Chemical Daily, March 6, 1996, pp. 492 to 497. Non-patent Document 2: "Recently technology on Synthetic Aromachemical", CMC Publishing, 1982, pp. 72 to 90. For the reasons above, there have been many reports of the studies on the method of preparing muscone, in particular, (-) - (R)-muscone . Among them, a method of producing an optically active muscone by 1, 4-conjugation methyl-addition reaction of 2-cyclopentadecenone is considered to be promising, and there are recently some reports on the methods of preparing (-)-(R)-muscone in asymmetric methylation reaction using an optically active ligand. For example, it has been reported that it is possible to obtain favorable results by using a compound having an amino alcohol chiral auxiliary group containing a bornane skeleton inpreparation (see Non-patent Document 3below) . However, the reported method of producing the (-) -(R) -muscone by using a chiral auxiliary group is yet to be commercialized, because it has disadvantages of demanding an extremely low reaction temperature of -78°C, an extended reaction time, and use of a chiral auxiliary group in an excessive amount of one equivalence or more . In another example, there is a report that a particular chiral phosphite compound gave a favorable result when various chiral phosphite ligands were examined in a catalytic amount (see Non-patent Document 4 below). However, the reported method shows a yield of 53% even at an inefficiently low concentration at a solvent/substrate rate of approximately 50 and thus, is not desirable. In yet another example, described is high-yield production of muscone by using a copper complex of 4-(cis-2,6-dimethylpiperidine)- (R)-dinaphthodioxaphosphepin or 4-(R,R-2,5-diphenyl-pyrrolidine)-(R)-dinaphthodioxaphosphepin as a chiral ligand (see Patent Document 1 below), but the literature does not disclose the reaction at higher concentration. When the reaction is carried out at higher concentration, conventional methods cause a problem of poor yield of the objective product by generation of high-molecular weight by-products. Further, the employment of an extreme reaction condition such as an extremely low temperature, a low concentration or an extended reaction period results in increase of a production cost. Low reaction yield also leads to increase of a production cost. Therefore, there exists an urgent need for a method of producing muscone economically at high yield without employing a reaction condition such as an extremely low temperature, a low concentration, or an extended reaction period.

Perkin Trans, I, 1193 (1992) Non-patent Document 4: Synlett 1999, No. 11, pp. 1181-1183 SUMMARY OF THE INVENTION PROBLEMS TO BE SOLVED BY THE INVENTION An object of the present invention, which has been made under the circumstances above, is to provide a method of producing muscone at high yield by 1,4-conjugation methyl-addition reaction of 2-cyclopentadecenone under a practical condition without employing an reaction condition such as extremely low temperature or low concentration. MEANS FOR SOLVING THE PROBLEMS After intensive studies to solve the problems above, the inventors have found that it is possible to obtain the objective muscone in high yield under higher concentration by steps of forming a new enol derivative by trapping an enol anion generated by 1, 4-conjugation methyl-addition reaction of 2-cyclopentadecenone with a suitable scavenger while restraining the generation of by-products and then decomposing the enol derivative by a common method and after further studies, completed the present invention.

Chem., 58, 7313 (1993) Non-patent Document 10: Tetrahedron Asymmetry, 13, 801 (2002) In the reactions described above, the optically active ligand represented by General Formula (IV) or (V) is used in an amount of normally approximately 0.1 to 20 mol%, preferably approximately 1.0 to 10 mol%, with respect to 1 mole of the 2-cyclopentadecenone (III). The 3-methyl-l-cyclopentadecenederivative (II) obtained in the enol anion-trapping reaction described above is a new compound unknown in the art, and is a compound which is stable, normally oily or powdery, and storable. Thus, the 3-methyl-l-cyclopentadecene derivative (II) obtained in the enol anion-trapping reaction may be purified, for example, by distillation, recrystallization, or column chromatography, or may be stored without purification and used as it is withdrawn from the storage container when the following production process is conducted. Specific examples of the compound represented by General Formula (II) include the following compounds. However, these compounds are illustrated only as examples, and the compounds represented by General Formula (II) are not limited to the following compounds. (Enol esters) 3-methyl-l-cyclopentadecenyl formate, 3-methyl-1-cyclopentadecenyl acetate, 3-methyl-l-cyclopentadecenyl propionate, 3-methyl-l-cyclopentadecenyl butyrate, 3-methyl-l-cyclopentadecenyl isobutyrate, 3-methyl-l-cyclopentadecenyl see-butyrate, 3-methyl-l-cyclopentadecenyl tert-butyrate, 3-methyl-l-cyclopentadecenyl valerate, 3-methyl-l-cyclopentadecenyl isovalerate, 3-methyl-l-cyclopentadecenyl hexanoate, 3-methyl-l-cyclopentadecenyl heptanoate, 3-methyl-l-cyclopentadecenyl octanoate, 3-methyl-l-cyclopentadecenyl nonanate, 3-methyl-l-cyclopentadecenyl decanoate, 3-methyl-l-cyclopentadecenyl undecanoate, 3-methyl-l-cyclopentadecenyl dodecanoate, 3-methyl-l-cyclopentadecenyl benzoate, 3-methyl-l-cyclopentadecenyl chloroacetate, and 3-methyl-l-cyclopentadecenyl phenoxyacetate. (Enol carbonates) 3-methyl-l-cyclopentadecenyl methyl carbonate, 3-methyl-l-cyclopentadecenyl ethyl carbonate, 3-methyl-l-cyclopentadecenyl tert-butyl carbonate, and 3-methyl-l-cyclopentadecenyl benzyl carbonate.

In the examples of the compounds, geometrical and optical isomers are not mentioned, but as the (E)-isomer, (Z)-isomer and a mixture of (E)- and (Z)-isomers thereof, as well as the (R)-isomer, (S)-isomer, and a mixture of (R)- and (S)-isomers thereof, there can be exemplified the above compounds similarly. In the reaction, the configuration in geometrical isomerism of the 3-methyl-l-cyclopentadecene derivative represented by General Formula (II) is governed by that of the 2-cyclopentadecene represented by General Formula (III). For example, when the (E) -isomer of 2-cyclopentadecene represented by General Formula (III) is used, a (Z)-3-methyl-l-cyclopentadecene derivative is obtained mainly as the 3-methyl-l-cyclopentadecene derivative represented by General Formula (II). In the reaction, the configuration on the 3-asymmetric carbon atom in the optically active 3-methyl-l-cyclopentadecene derivative represented by General Formula (Il-a) obtained in the presence of an optically active ligand is controlled by that of the optically active ligand used in the reaction. As a favorable example of the optically active ligand, there is illustrated 4-(cis-2,6-dimethylpiperidine)-(R)-ditetrahydronaphthodioxaphosphepin represented by the following Formula: (Figure Removed) When it is used, a (R)-3-methyl-l-cyclopentadecene derivative is obtained as the optically active 3-methyl-l-cyclopentadecene derivative represented by General Formula (Il-a). Other favorable examples of the optically active ligand include 4-(cis-2,6-dimethylpiperidine)-(R)-dinaphthodioxaphosphepin, 4-((R,R)-2,5-diphenylpyrrolidine)-(R)-dinaphthodioxa-phosphepin, and 4-((R,R)-2,5-diphenylpyrrolidine)-(R)-ditetrahydronaphthodioxaphosphepin, and similar results are obtained when these compounds are used. In the present invention, subsequent solvolysis of the enol moiety of the 3-methyl-l-cyclopentadecene derivative represented by General Formula (II): (Figure Removed) (wherein R represents a straight- or branched-chain acyl group which may have a substituent containing a heteroatom or an aromatic ring, a straight- or branched-chain alkyloxycarbonyl group which may have a substituent containing a heteroatom or an aromatic ring, a straight- or branched-chain alkyl group which may have a substituent containing a heteroatom or an aromatic ring, or a straight- or branched-chain silyl group which may have a substituent containing a heteroatom or an aromatic ring; and the wavy line is the same as that above) gives muscone represented by Formula (I): (Figure Removed) Any common known solvolytic method for enol compounds may be used as the solvolytic method of the invention. In the case of enol esters and enol carbonates, examples of the methods include a method of carrying out a reaction in a solvent in the presence of a basic catalyst. Examples of the basic catalyst used in this solvolysis include lithium hydroxide, sodium hydroxide, potassium hydroxide, magnesium hydroxide, calcium hydroxide, lithium carbonate, sodium carbonate, potassium carbonate, magnesium carbonate, calcium carbonate, lithium bicarbonate, sodium bicarbonate, potassium bicarbonate, lithium alkoxides (such as lithiummethoxide, lithium ethoxide, and lithium tert-butoxide), sodium alkoxides (such as sodium methoxide, sodium ethoxide, and sodium tert-butoxide), and potassium alkoxides (such as potassium methoxide, potassium ethoxide, and potassium tert-butoxide). The basic catalysts are preferably sodium hydroxide, potassium hydroxide, sodium methoxide, sodium ethoxide and the like because they are cheaper and have favorable flexibility in use, higher selectivity in reaction, and high yield. These basic catalysts may be used alone or in combination of two or more thereof, but it is preferable to be used alone. Alternatively in the case of enol ethers, the reaction may be carried out in a solvent in the presence of an acidic catalyst. Examples of the acidic catalyst used in the solvolysis include hydrofluoric acid, hydrochloric acid, hydrobromic acid, sulfuric acid, phosphoric acid, methanesulfonic acid, p-toluenesulfonic acid, acetic acid, chloroacetic acid, trifluoroacetic acid, and acidic ion-exchange resins. Favorable acidic catalysts include hydrochloric acid, sulfuric acid, andp-toluenesulfonicacidbecausetheyarecheaper, having favorable flexibility in use, and show higher reaction selectivity and high yield. These acidic catalysts may be used alone or in combination of two or more thereof, but it is preferable to be used alone. For example in the case of silyl enol ethers, the reaction may be carried out in a solvent in the presence of the acidic catalyst above, and examples of the acidic catalysts further include fluorine compounds such as boron trifluoride and quaternary ammonium fluoride salts. The solvent used in solvolysis is not particularly limited if it is a solvent allowing progress of solvolysis, and examples thereof include water, alcohols such as methanol, ethanol and isopropanol, and themixed solvents thereof. Among the solvents above, methanol and ethanol are favorable because they are cheaper and have favorable flexibility in use, higher reaction selectivity and high yield. Further, a cosolvent may be added as needed. Thecosolvent is not particularly limited if it is inert to the reaction, and examples of such organic solvents include ether solvents such as diethyl ether, diisopropyl ether, tetrahydrofuran, dimethoxyethane, and dioxane; hydrocarbon solvents such as hexane, heptane and octane; and aromatic solvents such as benzene, toluene, and xylene. The solvent is used in an amount of normally 0 . 5 to 100-times by volume, preferably I to 30-times by volume, with respect to 1 part by mass of the 3-methyl-l-cyclopentadecene derivative (II) . The reaction is carried out at normally approximately 0 to 250°C, preferably approximately 20 to 100°C, normally approximately for 10 minutes to 20 hours, preferably approximately for 30 minutes to 10 hours, but these conditions may be altered properly according to the amount of the solvent and catalyst used. The objective product may be isolated as needed after reaction by common post-treatment such as distillation or column chromatography. The reaction may be carried out either batchwise or continuously in the invention. Solvolysis of the enol moiety in the 3-methyl-l-cyclopentadecene derivative represented by General Formula (II) has been described above in detail. And the catalyst, solvent, reaction condition and the like in solvolysis of the optically active 3-methyl-l-cyclopentadecene derivative represented by General Formula (II-a) are the same as those described above. Thus, it is possible to prepare optically active muscone represented by General Formula (I-a) by solvolysis of the optically active 3-methyl-l-cyclopentadecene derivative represented by General Formula (II-a) in a similar manner. In the reaction, the configuration of the 3-asymmetric carbon atom on the optically active muscone represented by Formula (I-a) retains that of the optically active 3-methyl-l-cyclopentadecene derivative represented by General Formula (II-a). Thus, for example, when a (R)-3-methyl-l-cyclopentadecene derivative is used as the optically active 3-methyl-l-cyclopentadecene derivative represented by General Formula (II-a), (R)-muscone is obtained as muscone represented by Formula (I-a) in retaining an optical purity. The configuration of the optically active 3-methyl-l-cyclopentadecene derivative is controlled by that of the optically active ligand used in the reaction.
