【0003】
【発明が解決しようとする課題】
したがって本発明の目的は、一般式(I)で表されるヒドロキシエステル化合物の製造方法を提供することにある。
【0004】
【課題を解決するためめ手段】
本発明者らは上記課題を解決すべく、ラクトン類とヒドロキシ化合物(R2OH)との反応について鋭意研究を重ねた結果、固体酸触媒機能をもつ粘土鉱物を触媒として使用することにより、ヒドロキシエステル化合物(I)を合成しうることを見いだし、この知見に基づき本発明をなすに至った。
【0005】
【発明の実施の形態】
本発明において式(I)で表される化合物は、式(II)で表されるラクトン化合物とヒドロキシ化合物(R2OH)を粘土鉱物の存在下反応させて合成することができる。ラクトン化合物(II)は、環内にオルトーフェニレン基(−C6H4−)を有し、ラクトン鎖(−O−C(=O)−(CH2)n−)がこのオルト−フェニレン基に環化置換した構造をしている。このラクトン鎖部分に含まれるメチレン鎖((CH2)n)の数nは1または2をとることができる。
式(I)においてR2は、好ましくは、炭素数1〜16、より好ましくは1〜8のアルキル基、炭素数6〜14、より好ましくは6〜10のアリール基、炭素数7〜12、より好ましくは7〜10のアラルキル基、炭素数3〜14、より好ましくは3〜10のシクロアルキル基、へテロ原子として、酸素、窒素、硫黄原子などを有する5〜10員環のより好ましくは5〜6員環のへテロ環基が挙げられる。Rlとしては例えば、メチル、エチル、へプタデシルなどのアルキル基、フェニル、ナフチルなどのアリール基、ベンジル、フェネチルなどのアラルキル基、シクロペンチル、シクロへキシル、デカヒドロナフチルなどのシクロアルキル基、フリル、ピリジル、チエニル、キノリル、ピペリジル、ピラニルなどのへテロ環基及びそれらの置換誘導体が挙げられる。

このようなヒドロキシ化合物を、粘土鉱物の存在下、前記式(II)で表され
るラクトン化合物と反応させることにより、前記式(I)で表されるヒドロキシエステル化合物が得られる。
本発明のヒドロキシエステル化合物の合成方法において用いる粘土鉱物は、固体酸としての性質を有するものであれば特に制限はなく、例えばモンモリロナイト、バイデライト、サポナイト、ヘクトライト、フラー土などを用いることができ、モンモリロナイトが特に好ましい。粘土鉱物の使用量は適宜に決定することができるが、通常、重量比で、式(II)のラクトン化合物1に対し0.3〜2である。
これを前記ヒドロキシ化合物及び式(II)のラクトン化合物とともに加え、加熱撹拌して反応させる。
式(II)のラクトン化合物とヒドロキシ化合物との反応モル比は、特に制限はないが、1:3〜1:10の範囲が好ましい。
反応温度は好ましくは60〜100℃であり、より.好ましくは70℃以上であり、反応時間は特に制限はないが、通常6〜30時間である。
反応は、溶媒中、あるいは無溶媒下いずれでもよいが、溶媒中で行うのが好ましく、ヒドロキシル化合物自身を過剰に用いて溶媒とする場合及びヒドロキシル化合物以外を溶媒として用いる場合がある。ヒドロキシル化合物以外の溶媒としては、ジクロロメタン、アセトニトリル、ジオキサンなどの溶媒が具体例として挙げられる。
反応後は、そのまま簡単なろ過操作で触媒の粘土鉱物を除き、溶媒を除去すれば目的の式(I)で表されるヒドロキシエステル化合物を得ることができる。
なお、粘土鉱物は環境受容型触媒として知られているが、ラクトンのヒドロキシエステル化反応に応用されたのは本発明がはじめての例である。

[0002]
[Prior art]
A hydroxyester compound having a phenylene group is expected to be used in a wide range of applications such as synthesis of a molecular recognition agent, but an effective production method is not known due to difficulty in synthetic chemistry .
[0003]
[Problems to be solved by the invention]
Accordingly, an object of the present invention is to provide a method for producing a hydroxy ester compound represented by the general formula (I) .
[0004]
[Means for solving the problems]
In order to solve the above-mentioned problems, the present inventors have conducted extensive research on the reaction between lactones and hydroxy compounds (R 2 OH). As a result, by using a clay mineral having a solid acid catalyst function as a catalyst, It has been found that the ester compound (I) can be synthesized, and the present invention has been made based on this finding.
[0005]
DETAILED DESCRIPTION OF THE INVENTION
In the present invention, the compound represented by the formula (I) can be synthesized by reacting the lactone compound represented by the formula (II) and the hydroxy compound (R 2 OH) in the presence of a clay mineral. The lactone compound (II) has an orthophenylene group (—C 6 H 4 —) in the ring, and the lactone chain (—O—C (═O) — (CH 2 ) n —) is this ortho-phenylene. It has a structure in which the group is cyclized and substituted. The number n of methylene chains ((CH 2 ) n) contained in the lactone chain portion can be 1 or 2.
In formula (I), R 2 is preferably an alkyl group having 1 to 16 carbon atoms, more preferably 1 to 8 carbon atoms, an aryl group having 6 to 14 carbon atoms, more preferably 6 to 10 carbon atoms, 7 to 12 carbon atoms, More preferably, the aralkyl group having 7 to 10 carbon atoms, the cycloalkyl group having 3 to 14 carbon atoms, more preferably 3 to 10 carbon atoms, and more preferably a 5- to 10-membered ring having oxygen, nitrogen, sulfur atoms, etc. as a hetero atom. A 5- to 6-membered heterocyclic group is exemplified. Examples of R 1 include alkyl groups such as methyl, ethyl, and heptadecyl, aryl groups such as phenyl and naphthyl, aralkyl groups such as benzyl and phenethyl, cycloalkyl groups such as cyclopentyl, cyclohexyl, and decahydronaphthyl, furyl, Examples include heterocyclic groups such as pyridyl, thienyl, quinolyl, piperidyl, pyranyl, and substituted derivatives thereof.
The hydroxy compound (R 2 OH) is preferably an aliphatic alcohol, for example, a primary alcohol such as methanol or ethanol, or a secondary alcohol such as 2-propanol, 2-butanol or 2-pentanol. In addition, alicyclic alcohols such as cyclohexanol and aryl alcohols such as phenol can also be used.
By reacting such a hydroxy compound with a lactone compound represented by the formula (II) in the presence of a clay mineral, a hydroxy ester compound represented by the formula (I) is obtained.
The clay mineral used in the method for synthesizing the hydroxy ester compound of the present invention is not particularly limited as long as it has properties as a solid acid. For example, montmorillonite, beidellite, saponite, hectorite, fuller earth, etc. can be used. Montmorillonite is particularly preferred. Although the usage-amount of a clay mineral can be determined suitably, it is 0.3-2 normally with respect to the lactone compound 1 of a formula (II) by weight ratio.
This is added together with the hydroxy compound and the lactone compound of the formula (II) and reacted by heating and stirring.
The reaction molar ratio of the lactone compound of formula (II) and the hydroxy compound is not particularly limited, but is preferably in the range of 1: 3 to 1:10.
The reaction temperature is preferably 60-100 ° C, and more. Preferably it is 70 degreeC or more, Although reaction time does not have a restriction | limiting in particular, Usually, it is 6 to 30 hours.
The reaction may be carried out either in a solvent or in the absence of a solvent, but it is preferably carried out in a solvent. In some cases, the hydroxyl compound itself is used in excess and used as the solvent, or a compound other than the hydroxyl compound is used as the solvent. Specific examples of the solvent other than the hydroxyl compound include solvents such as dichloromethane, acetonitrile, and dioxane.
After the reaction, the target hydroxy ester compound represented by the formula (I) can be obtained by removing the catalyst clay mineral by a simple filtration operation and removing the solvent.
Although clay minerals are known as environment-accepting catalysts, this is the first example in which the present invention has been applied to a lactone hydroxyesterification reaction.

【The invention's effect】
As described above, according to the present invention, a hydroxy ester compound can be easily obtained. This compound has both a hydroxyl group and an ester group that are highly reactive in the molecule, so it can be used as a reaction material for synthesizing functional substances such as molecular recognition agents, as well as a novel host compound that utilizes a cyclic structure. It is also used as a raw material for the production of surfactants and surfactants and is industrially useful. Such a compound can be produced by a clean and simple method free from environmental pollution by using a clay mineral as a catalyst.
