Description
本発明は有機合成の分野に関し、特に触媒及びその製造方法、及びN−アルキルイミダゾール系化合物の製造方法に関する。 The present invention relates to the field of organic synthesis, particularly to a catalyst and a method for producing the same, and a method for producing an N-alkylimidazole compound.
N−アルキルイミダゾール系化合物は、非常に重要なファインケミカルであり、イオン液体、医薬品、抗菌剤、酵素阻害剤、及び他のファインケミカルに広く使用されている。例えば、それはイミダゾリウムイオン液体の最も重要な出発物質であり、それを通して多種多様なイオン液体を合成することができ、それはまた医薬原料であるメトロニダゾール、セクニダゾール及び獣医薬ジメガゾールの合成のためのベース構造でもある。N-アルキルイミダゾールは、5員複素環の1つの窒素原子上に孤立電子対を有し、また、一定の塩基性及び求核性を有するので、有機合成における有機配位子及び触媒としても使用できる。中、長炭素鎖のN−アルキルイミダゾールは、優れた表面特性を有し、両性界面活性剤として最も一般的に使用されているカチオン性官能基の1つであり、エポキシ樹脂の硬化剤としても広く使用できる。 N-alkylimidazole compounds are very important fine chemicals and are widely used in ionic liquids, pharmaceuticals, antibacterial agents, enzyme inhibitors, and other fine chemicals. For example, it is the most important starting material for imidazolium ionic liquids, through which a wide variety of ionic liquids can be synthesized, it is also the base structure for the synthesis of the medicinal raw materials metronidazole, secnidazole and veterinary dimegazol. But also. Since N-alkylimidazole has a lone electron pair on one nitrogen atom of a 5-membered heterocycle and has a certain basicity and nucleophilicity, it is also used as an organic ligand and catalyst in organic synthesis. it can. Medium and long carbon chain N-alkylimidazoles have excellent surface properties, are one of the most commonly used cationic surfactants as amphoteric surfactants, and are also used as curing agents for epoxy resins. Can be widely used.
N-アルキルイミダゾールは、このような独特の物理的化学的性質、及び、広い用途の可能性を有する。しかしながら、先行文献に報告されているN-アルキルイミダゾール製造方法は、苛酷な反応条件、不純な生成物、及び触媒の再利用の不可能性などの欠点を有する。特許文献1には、酸結合剤としての水素化ナトリウムを、相間移動触媒としてのテトラブチルアンモニウムヨージドを使用するセチルイミダゾール製造方法が開示されているが、この方法に使用される水素化ムナトリウは高価であって、安全生産に不利である。また、Soo Y. Koは、非特許文献1において、均一条件下で、触媒としてのアゾジカルボン酸ジエチルまたはジイソプロピルエステルを使用する一連のN−アルキルイミダゾール系化合物合成方法という報告を行っている。しかしながら、この合成方法では、触媒価格が高い上、触媒が分離しにくく、繰り返し使用することが困難なので、規模化生産には不利である。 N-alkylimidazoles have such unique physical and chemical properties and potential for a wide range of applications. However, the N-alkylimidazole production methods reported in the prior art have drawbacks such as harsh reaction conditions, impure products, and the inability to reuse the catalyst. Patent Document 1 discloses a method for producing cetylimidazole using sodium hydride as an acid binder and tetrabutylammonium iodide as a phase transfer catalyst, but the hydrogenated munatoriu used in this method is It is expensive and disadvantageous for safe production. In addition, Soo Y. Ko reports in Non-Patent Document 1 a series of methods for synthesizing N-alkylimidazole compounds using diethyl azodicarboxylate or diisopropyl ester as a catalyst under uniform conditions. However, this synthesis method is disadvantageous for large-scale production because the catalyst price is high, the catalyst is difficult to separate, and it is difficult to use it repeatedly.
このようなN-アルキルイミダゾールの製造方法では、反応条件が過酷であり、生成物が不純であり、触媒をリサイクルすることができない等の欠点を有する。 Such a method for producing N-alkylimidazole has drawbacks such as severe reaction conditions, impure product, and inability to recycle the catalyst.
本発明は、触媒及びその製造方法、ならびにN−アルキルイミダゾール系化合物の製造方法を提供する。本発明により提供される触媒がN-アルキルイミダゾール系化合物の製造に使用される場合、反応条件が温和であるだけでなく、生成物選択性が高く、かつ触媒は容易にリサイクルされて再使用することができる。 The present invention provides a catalyst and a method for producing the same, and a method for producing an N-alkylimidazole compound. When the catalyst provided by the present invention is used in the production of N-alkylimidazole compounds, not only the reaction conditions are mild, but also the product selectivity is high, and the catalyst is easily recycled and reused. be able to.
