【産業上の利用分野】
本発明は、2,3−ジヒドロポリプレニルモノホスフェートの製造方法及びその中間体化合物とその中間体化合物の製造方法に関する。本発明の方法によって製造される2,3−ジヒドロポリプレニルモノホスフェートのうち、一般式(I)においてnが15〜22である2,3−ジヒドロポリプレニルモノホスフェートは、哺乳動物の体内に広く分布し、生体の生命維持の上で極めて重要な働きをしている糖蛋白質の合成に律速因子として関与する化合物として知られており、また肝機能改善薬、抗炎症剤、免疫増強剤などの医薬品としても有用な化合物である。また、一般式(I)においてnが9である2,3−ジヒドロポリプレニルモノホスフェートは制癌剤として有用な化合物として知られている(特開昭60−67424公報参照)。
【0002】
【従来の技術】
従来、2,3−ジヒドロポリプレニルモノホスフェートを合成する方法としては、2,3−ジヒドロポリプレノールを原料とした種々の方法が知られている。
例えば、トリクロロアセトニトリルの存在下にリン酸水素二トリエチルアンモニウムを用いる方法(Biochemistry, 14, 412(1975))、オキシ塩化リンを用いる方法(FEBS Lett., 131, 310(1981))、オキシ塩化リンのP−Cl結合を一部変換した試薬である式(V)
【化11】

で示されるオキシ塩化リン誘導体(以下、これをオキシ塩化リン誘導体(V)と記す)を使用する方法(Chem. Phys. Lipids., 17, 193(1976))、さらに式(VI)
【化12】
Figure 0003619277
で示されるオキシ塩化リン誘導体(以下、これをオキシ塩化リン誘導体(VI)と記す)を使用する方法(J. Biol. Chem., 249, 6316(1974))などがある。
【0003】
しかしながら、これらの方法には下記の問題点があるために、2,3−ジヒドロポリプレニルモノホスフェートを大量にかつ医薬用途用に製造する方法として適用するのは難しい。すなわち、トリクロロアセトニトリルの存在下にリン酸水素二トリエチルアンモニウムを用いる方法では、2,3−ジヒドロポリプレノールのピロリン酸エステルの副生が避けられず、しかも、このピロリン酸エステルと2,3−ジヒドロポリプレニルモノホスフェートとの分離が困難である。オキシ塩化リン誘導体(V)を用いる方法では、このオキシ塩化リン誘導体(V)が非常に限定された条件下での反応によってしか得られないため、その入手が容易でないという難点がある。また、オキシ塩化リン誘導体(VI)を用いる方法では、2,3−ジヒドロポリプレノールとの縮合物を加水分解して2,3−ジヒドロポリプレニルモノホスフェートを得る反応において、不安定でかつ毒性を有する四酢酸鉛を使用するため、工業的生産方法としては適当ではない。更に、オキシ塩化リンを用いる方法では、目的とする2,3−ジヒドロポリプレニルモノホスフェートの生成とともに、TLC分析(TLC板:Merck ♯5715,展開液:クロロホルム−メタノール−水(65:25:4))において、そのTLC上、2,3−ジヒドロポリプレニルモノホスフェートのRf値0.5に対し、Rf値0.6の不純物が副生する。この不純物はシリカゲル、逆相シリカゲル、ジエチルアミノセルローズ等を使用したカラムクロマトグラフィー法、結晶化法等による精製では完全に除去することはできない。この方法において、反応溶媒をヘキサンからエーテル系溶媒に変更する改良により上記不純物の生成をかなり抑えることができるようになった(特公平5−44953)。しかし、この改良方法においても、上記不純物の生成を完全に抑えることはできないため、上記のような種々の精製法を用いてもこの不純物を完全に除くことは困難であった。
【0004】
【発明が解決しようとする課題】
従って、これら従来技術の有する欠点が全て解消された、より簡単な反応操作によってしかも医薬品に求められる極めて純度の高い2,3−ジヒドロポリプレニルモノホスフェートを高収率で製造する方法の解明が求められているところである。さらにまたこの2,3−ジヒドロポリプレニルモノホスフェートの製造方法において、従来方法とは異なった反応経路を取ることによって予想され得る新規な中間体化合物及びその中間体化合物の製造方法の解明も求められるところである。
【0005】
【課題を解決するための手段】
本発明者等は上記課題を解決するため鋭意研究を重ねた結果、2,3−ジヒドロポリプレノールをビス(2−クロロフェニル)ホスホリルクロライドと反応させた後、生成したリン酸トリエステルを加水分解して、2,3−ジヒドロポリプレニルモノホスフェートを効率的に得る製造方法を見出だし、本発明を完成させた。
【0006】
また上記した2,3−ジヒドロポリプレノールとビス(2−クロロフェニル)ホスホリルクロライドとの反応で得られるリン酸トリエステルを加水分解して得られる生成物を特定の溶媒で精製することにより、極めて純度の高い目的物の2,3−ジヒドロポリプレニルモノホスフェートをうることができることを見出だし、本発明を完成させた。
【0007】
さらにまた、上記した従来法とは異なる新たな反応経路を経由して目的物を得る過程で新規な中間体化合物を見出し、同時にこの中間体化合物の新規な製造方法を見出して本発明を完成させた。

【0017】
この反応は溶媒を用いることなく行うことができるが、反応を円滑に進め、反応温度の制御を容易にし、また反応混合物の取り扱いを容易にし得るなどのために溶媒を用いて行うことが好ましい。ここで用いる溶媒としてはベンゼン、トルエン、キシレン等の芳香族炭化水素系溶媒、ジクロロメタン、クロロホルム、1,2−ジクロロエタン等のハロゲン系溶媒、THF(テトラヒドロフラン)、DME(1,2−ジメトキシエタン)、ジエチルエーテル、1,4−ジオキサン等のエーテル系溶媒等が挙げられ、その使用量は反応に用いる原料化合物の合計重量の通常5〜30倍量程度の量である。そしてこの反応は室温から溶媒の沸点までの範囲の温度、普通20〜60℃程度の温度範囲内で行なわれ、そして通常1〜5時間程度の時間で反応は完結する。

この発明の方法の次の反応段階であるリン酸トリエステル(IV)の加水分解反応は、アルカリ金属、アルカリ土類金属の水酸化物等の存在下に行なわれる。アルカリ金属の水酸化物としては、例えば水酸化ナトリウム、水酸化カリウムなどが使用され、またアルカリ土類金属の水酸化物としては、例えば水酸化バリウム、水酸化ストロンチウムなどが使用される。アルカリ金属またはアルカリ土類金属の水酸化物の使用量は、使用するアルカリ金属またはアルカリ土類金属の水酸化物の種類によっても異なるが、通常リン酸トリエステル(II)に対して約2〜25モル当量である。この加水分解反応は反応溶媒中で行うのが好ましく、使用される溶媒としては、例えばテトラヒドロフラン(THF)、1,2−ジメトキシエタン(DME)、ジエチルエーテル、1,4−ジオキサン等のエーテル系溶媒が挙げられるが、好ましくは1,4−ジオキサンが使用される。溶媒の使用量はリン酸トリエステル(II)に対し約5〜100倍量、好ましくは10〜50倍量の範囲である。反応は一般に溶媒の還流温度で行なうのが好ましく、使用する溶媒によっても異なるが通常約2〜24時間程度で完結する。

加水分解反応後の精製方法については、シリカゲルカラムクロマトグラフィー、結晶化、蒸留等を試みたが、加水分解後に生成した2,3−ジヒドロポリプレニルモノホスフェート(I)と2−クロロフェノールの混合物から、2−クロロフェノールを完全に除去することは困難であった。そこで、特定の溶媒による抽出方法を研究したところ、粗製2,3−ジヒドロポリプレニルモノホスフェート(I)を非極性溶媒に溶解し、この非極性溶媒と混和しない溶媒で抽出洗浄することにより、効率的に分離精製できることを見出した。
【0020】
すなわちここで2,3−ジヒドロポリプレニルモノホスフェート(I)を含む粗加水分解生成物を溶解するのに使用する非極性溶媒としては、ペンタン、ヘキサン、ヘプタン、オクタン等の飽和炭化水素系溶媒が好ましく、ヘキサンが特に好ましい。溶媒の使用量は、リン酸トリエステル(IV)に対し通常10〜50倍量の範囲である。また、この非極性溶媒と混和しない溶媒としては、アセトニトリル、メタノール、ジメチルホルムアミド(DMF)等が挙げられるが、アセトニトリルが特に好ましい。溶媒の使用量はリン酸トリエステル(IV)に対し通常5〜30倍量である。抽出洗浄はTLCで2−クロロフェノールが完全に除去されるのを確認しながら行ない、通常2回以上、好ましくは3〜5回行なう。このようにして加水分解反応により生成した2,3−ジヒドロポリプレニルモノホスフェート(I)と2−クロロフェノールとは極めて効率的に分離することが出来、高純度の2,3−ジヒドロポリプレニルモノホスフェート(I)を容易に得ることが出来る。

[Industrial application fields]
The present invention relates to a method for producing 2,3-dihydropolyprenyl monophosphate, an intermediate compound thereof, and a method for producing the intermediate compound. Among the 2,3-dihydropolyprenyl monophosphates produced by the method of the present invention, 2,3-dihydropolyprenyl monophosphates in which n is 15 to 22 in the general formula (I) are widely used in the body of mammals. It is known as a compound that participates as a rate-limiting factor in the synthesis of glycoproteins that are distributed and play an extremely important role in maintaining the life of living organisms. It is also known as a liver function improver, anti-inflammatory agent, immune enhancer, etc. It is also a useful compound as a pharmaceutical product. In addition, 2,3-dihydropolyprenyl monophosphate in which n is 9 in the general formula (I) is known as a useful compound as an anticancer agent (see JP-A-60-67424).
[0002]
[Prior art]
Conventionally, as a method for synthesizing 2,3-dihydropolyprenyl monophosphate, various methods using 2,3-dihydropolyprenol as a raw material are known.
For example, a method using ditriethylammonium hydrogen phosphate in the presence of trichloroacetonitrile (Biochemistry,14412 (1975)), a method using phosphorus oxychloride (FEBS Lett.,131, 310 (1981)), which is a reagent obtained by partially converting the P—Cl bond of phosphorus oxychloride (V)

(Hereinafter referred to as phosphorus oxychloride derivative (V)) (Chem. Phys. Lipids.,)17, 193 (1976)) and further formula (VI)

(Hereinafter referred to as phosphorus oxychloride derivative (VI)) (J. Biol. Chem.,2496316 (1974)).
[0003]
However, since these methods have the following problems, it is difficult to apply 2,3-dihydropolyprenyl monophosphate in a large amount for pharmaceutical use. That is, in the method using ditriethylammonium hydrogen phosphate in the presence of trichloroacetonitrile, the by-product of pyrophosphate ester of 2,3-dihydropolyprenol is unavoidable. Separation from polyprenyl monophosphate is difficult. In the method using the phosphorus oxychloride derivative (V), since this phosphorus oxychloride derivative (V) can be obtained only by a reaction under very limited conditions, it is difficult to obtain the phosphorus oxychloride derivative (V). In the method using phosphorus oxychloride derivative (VI), it is unstable and toxic in the reaction of hydrolyzing the condensate with 2,3-dihydropolyprenol to obtain 2,3-dihydropolyprenyl monophosphate. Since lead tetraacetate is used, it is not suitable as an industrial production method. Further, in the method using phosphorus oxychloride, the desired 2,3-dihydropolyprenyl monophosphate is produced and TLC analysis (TLC plate: Merck # 5715, developing solution: chloroform-methanol-water (65: 25: 4 )), An impurity having an Rf value of 0.6 is by-produced on the TLC with respect to the Rf value of 0.5 of 2,3-dihydropolyprenyl monophosphate. This impurity cannot be completely removed by purification by column chromatography, crystallization or the like using silica gel, reverse phase silica gel, diethylaminocellulose or the like. In this method, the generation of the impurities can be considerably suppressed by improving the reaction solvent from hexane to an ether solvent (Japanese Patent Publication No. 5-44953). However, even in this improved method, the generation of the impurity cannot be completely suppressed, and therefore it is difficult to completely remove the impurity even by using various purification methods as described above.
[0004]
[Problems to be solved by the invention]
Therefore, it is necessary to elucidate a method for producing 2,3-dihydropolyprenyl monophosphate with a high yield, which is required for pharmaceuticals, by a simple reaction operation, in which all the disadvantages of these conventional techniques are eliminated. It is being done. Furthermore, in this method for producing 2,3-dihydropolyprenyl monophosphate, it is required to elucidate a novel intermediate compound that can be expected by taking a reaction route different from the conventional method and a method for producing the intermediate compound. By the way.
[0005]
[Means for Solving the Problems]
As a result of intensive studies to solve the above problems, the present inventors reacted 2,3-dihydropolyprenol with bis (2-chlorophenyl) phosphoryl chloride, and then hydrolyzed the produced phosphate triester. Thus, a production method for efficiently obtaining 2,3-dihydropolyprenyl monophosphate was found, and the present invention was completed.
[0006]
Moreover, by purifying the product obtained by hydrolyzing the phosphoric acid triester obtained by the reaction of 2,3-dihydropolyprenol and bis (2-chlorophenyl) phosphoryl chloride as described above with a specific solvent, it is extremely pure. It was found that a 2,3-dihydropolyprenyl monophosphate having a high target value can be obtained, and the present invention has been completed.
[0007]
Furthermore, a novel intermediate compound was found in the process of obtaining the target product through a new reaction route different from the conventional method described above, and at the same time, a novel method for producing this intermediate compound was found to complete the present invention. It was.

In the method of the present invention, this bis (2-chlorophenyl) is used for the reaction of 2,3-dihydropolyprenol represented by the general formula (II) and bis (2-chlorophenyl) phosphoryl chloride represented by the formula (III). Phosphoryl chloride is used in a range of 1 to 5 molar equivalents, preferably 1.1 to 2 molar equivalents relative to 2,3-dihydropolyprenol. This reaction can be carried out by mixing the two compounds in the above proportions, but is preferably carried out in the presence of a basic substance. Examples of basic substances used here include organic bases such as triethylamine, pyridine, 4-dimethylaminopyridine (DMAP), sodium hydroxide, potassium hydroxide, sodium carbonate, potassium carbonate, calcium hydroxide, sodium hydride and the like. An inorganic base may be mentioned, and the amount used may be 1 molar equivalent or more with respect to 2,3-dihydropolyprenol (II), but it is usually used in an amount in the range of about 1.1 to 3 molar equivalents.

Although this reaction can be carried out without using a solvent, it is preferred to carry out the reaction using a solvent in order to facilitate the reaction, facilitate the control of the reaction temperature, and facilitate the handling of the reaction mixture. As the solvent used here, aromatic hydrocarbon solvents such as benzene, toluene and xylene, halogen solvents such as dichloromethane, chloroform and 1,2-dichloroethane, THF (tetrahydrofuran), DME (1,2-dimethoxyethane), Examples include ether solvents such as diethyl ether and 1,4-dioxane, and the amount used is usually about 5 to 30 times the total weight of the raw material compounds used in the reaction. This reaction is carried out at a temperature ranging from room temperature to the boiling point of the solvent, usually within a temperature range of about 20 to 60 ° C., and the reaction is usually completed in about 1 to 5 hours.
[0018]
The hydrolysis reaction of phosphoric acid triester (IV), which is the next reaction step of the method of the present invention, is carried out in the presence of an alkali metal, alkaline earth metal hydroxide or the like. Examples of the alkali metal hydroxide include sodium hydroxide and potassium hydroxide, and examples of the alkaline earth metal hydroxide include barium hydroxide and strontium hydroxide. The amount of alkali metal or alkaline earth metal hydroxide used varies depending on the type of alkali metal or alkaline earth metal hydroxide used, but is generally about 2 to 2 with respect to the phosphate triester (II). 25 molar equivalents. This hydrolysis reaction is preferably carried out in a reaction solvent. Examples of the solvent used include ether solvents such as tetrahydrofuran (THF), 1,2-dimethoxyethane (DME), diethyl ether, and 1,4-dioxane. 1,4-dioxane is preferably used. The amount of the solvent used is in the range of about 5 to 100 times, preferably 10 to 50 times the amount of phosphoric acid triester (II). In general, the reaction is preferably carried out at the reflux temperature of the solvent and is usually completed in about 2 to 24 hours, although it varies depending on the solvent used.
[0019]
As for the purification method after the hydrolysis reaction, silica gel column chromatography, crystallization, distillation, etc. were tried, but from the mixture of 2,3-dihydropolyprenyl monophosphate (I) and 2-chlorophenol produced after hydrolysis. It was difficult to completely remove 2-chlorophenol. Therefore, when an extraction method using a specific solvent was studied, it was found that the crude 2,3-dihydropolyprenyl monophosphate (I) was dissolved in a nonpolar solvent and extracted and washed with a solvent immiscible with the nonpolar solvent. It was found that it can be separated and purified automatically.
[0020]
That is, here, as the nonpolar solvent used for dissolving the crude hydrolysis product containing 2,3-dihydropolyprenyl monophosphate (I), saturated hydrocarbon solvents such as pentane, hexane, heptane, and octane are used. Hexane is preferred, and particularly preferred. The amount of the solvent used is usually in the range of 10 to 50 times the amount of phosphoric acid triester (IV). Examples of the solvent immiscible with the nonpolar solvent include acetonitrile, methanol, dimethylformamide (DMF), and the like, and acetonitrile is particularly preferable. The amount of the solvent used is usually 5 to 30 times the amount of the phosphoric acid triester (IV). Extraction washing is performed while confirming that 2-chlorophenol is completely removed by TLC, and is usually performed twice or more, preferably 3 to 5 times. Thus, 2,3-dihydropolyprenyl monophosphate (I) and 2-chlorophenol produced by the hydrolysis reaction can be separated very efficiently, and high-purity 2,3-dihydropolyprenyl monophosphate can be obtained. Phosphate (I) can be easily obtained.
[0021]
【The invention's effect】
According to the method of the present invention described above, the desired 2,3-dihydropolyprenyl monophosphate (I) can be efficiently produced without causing problems in the conventional method. Similarly, optically active 2,3-dihydropolyprenyl monophosphate (I) can also be efficiently produced by the method of the present invention.
