Description
本発明はアルコール化合物の製造方法に関する。 The present invention relates to a method for producing an alcohol compound.
1,2−ビス(ヒドロキシメチル)シクロヘキサン、1,2−ビス(ヒドロキシメチル)−4−シクロヘキセン等の架橋されていてもよい環状炭化水素基を有するアルコール化合物は、例えば医薬合成中間体として有用であり(例えば特許文献1参照。)、その製造方法としては、式(1)
(式中、A1は架橋されていてもよい環状炭化水素基を表わし、A2およびA3は、それぞれ同一または相異なって、単結合または炭素数1〜2のアルキレン基を表わす。Rは低級アルキル基を表わし、Yは水素原子または−CO2Rで示される基を表わす。)
で示されるエステル化合物と水素化リチウムアルミニウムと反応させる方法が知られている(例えば特許文献1、非特許文献1参照。)。しかしながら、水素化リチウムアルミニウムは取扱いに注意を要する禁水性の試薬であるため、反応系内の水分管理を厳密に行う必要があり、また、反応後の後処理において副生するアルミニウム化合物の除去操作も煩雑であり、必ずしも工業的に十分満足し得る製造方法とは言えなかった。
Alcohol compounds having a cyclic hydrocarbon group which may be cross-linked such as 1,2-bis (hydroxymethyl) cyclohexane and 1,2-bis (hydroxymethyl) -4-cyclohexene are useful as, for example, pharmaceutical synthesis intermediates. Yes (for example, refer to Patent Document 1).
(In the formula, A 1 represents a cyclic hydrocarbon group which may be crosslinked, and A 2 and A 3 are the same or different and each represents a single bond or an alkylene group having 1 to 2 carbon atoms. R represents Represents a lower alkyl group, and Y represents a hydrogen atom or a group represented by —CO 2 R.)
There is known a method of reacting an ester compound represented by the formula (I) with lithium aluminum hydride (see, for example, Patent Document 1 and Non-Patent Document 1). However, lithium aluminum hydride is a water-inhibiting reagent that requires careful handling. Therefore, it is necessary to strictly control the water content in the reaction system, and to remove the by-product aluminum compound in the post-treatment after the reaction. However, it is not necessarily a manufacturing method that is sufficiently satisfactory industrially.
一方、水素化リチウムアルミニウムに比べて取扱いの容易な水素化ホウ素ナトリウムを、塩化アルミニウムとともに用いる方法も知られている(例えば非特許文献2参照。)が、反応後の後処理において、除去操作が煩雑なアルミニウム化合物を副生するため、必ずしも工業的に十分満足し得るものではなかった。 On the other hand, a method of using sodium borohydride, which is easier to handle than lithium aluminum hydride, together with aluminum chloride is also known (see, for example, Non-Patent Document 2). Since a complicated aluminum compound is by-produced, it is not always satisfactory industrially.
このような状況のもと、本発明者は、取扱いが容易な試剤を用いて、前記式(1)で示されるエステル化合物からアルコール化合物をより工業的に有利に製造する方法を開発すべく検討したところ、水素化ホウ素ナトリウム等の水素化ホウ素化合物を用い、メタノールの存在下に反応を行うことにより、容易に還元反応が進行し、目的とするアルコール化合物を得ることができることを見出し、本発明に至った。 Under such circumstances, the present inventor has studied to develop a method for producing an alcohol compound from the ester compound represented by the above formula (1) in an industrially advantageous manner using a reagent that is easy to handle. As a result, it was found that by using a borohydride compound such as sodium borohydride and carrying out the reaction in the presence of methanol, the reduction reaction easily proceeds and the desired alcohol compound can be obtained. It came to.
すなわち本発明は、式(1)
(式中、A1は架橋されていてもよい環状炭化水素基を表わし、A2およびA3は、それぞれ同一または相異なって、単結合または炭素数1〜2のアルキレン基を表わす。Rは低級アルキル基を表わし、Yは水素原子または−CO2Rで示される基を表わす。)
で示されるエステル化合物と水素化ホウ素化合物とを、有機溶媒中、メタノールの存在下に反応させることを特徴とする式(2)
(式中、A1、A2およびA3は上記と同一の意味を表わし、Qは、Yが水素原子のときに水素原子を、Yが−CO2Rで示される基のときにヒドロキシメチル基を表わす。)
で示されるアルコール化合物の製造方法を提供するものである。
That is, the present invention provides the formula (1)
(In the formula, A 1 represents a cyclic hydrocarbon group which may be crosslinked, and A 2 and A 3 are the same or different and each represents a single bond or an alkylene group having 1 to 2 carbon atoms. R represents Represents a lower alkyl group, and Y represents a hydrogen atom or a group represented by —CO 2 R.)
Wherein the ester compound represented by the formula (2) is reacted with a borohydride compound in an organic solvent in the presence of methanol.
(Wherein A 1 , A 2 and A 3 represent the same meaning as described above, and Q represents a hydrogen atom when Y is a hydrogen atom, and hydroxymethyl when Y is a group represented by —CO 2 R). Represents a group.)
The manufacturing method of the alcohol compound shown by is provided.
本発明によれば、取扱いが容易な水素化ホウ素化合物を用いて、簡便にアルコール化合物を製造することができ、また反応後の後処理も容易であるため、工業的により有利な製造方法である。 According to the present invention, an alcohol compound can be easily produced using a borohydride compound that is easy to handle, and the post-treatment after the reaction is easy, which is an industrially more advantageous production method. .
