Description

重水素化方法および重水素化触媒Deuteration method and deuteration catalyst
 本発明は、遷移金属触媒およびそれを用いる有機化合物の重水素化方法に関し、特に、N-ヘテロ環状カルベン(NHC)型配位子の前駆体、およびその配位子を含む重水素化触媒に関する。 The present invention relates to a transition metal catalyst and a method for deuterating an organic compound using the same, and more particularly to a precursor of an N-heterocyclic carbene (NHC) type ligand and a deuteration catalyst containing the ligand. .
 重水素化された化合物は、化学反応機構の解明や、体内動態解析に有用であるほか、医薬品の生理活性や薬物相互作用の制御において効果があることが知られている。とりわけ、高い重水素化率で重水素を導入した化合物が必要とされており、効率的な重水素導入法の必要性が近年急激に高まってきている。 Deuterated compounds are known to be useful for elucidation of chemical reaction mechanisms and pharmacokinetic analysis, and are effective in controlling physiological activities of drugs and drug interactions. In particular, a compound in which deuterium is introduced at a high deuteration rate is required, and the need for an efficient deuterium introduction method has increased rapidly in recent years.
 特に、芳香環は生理活性物質に遍在する重要構造であり、芳香環への様々な重水素化手法が検討されている。芳香環の触媒的重水素化手法として、水素/重水素(H/D)交換反応が盛んに研究されているが、当該方法では、高価な重溶媒等の重水素化合物を大量に使用する必要があるのに加え、反応点の制御が難しく、高い重水素化率で重水素化生成物を得ることが困難である(非特許文献1参照)。 Especially, the aromatic ring is an important structure ubiquitous in the physiologically active substance, and various deuteration methods for the aromatic ring have been studied. Hydrogen / deuterium (H / D) exchange reaction has been actively studied as a catalytic deuteration method for aromatic rings, but this method requires the use of a large amount of deuterium compounds such as expensive heavy solvents. In addition, the reaction point is difficult to control and it is difficult to obtain a deuterated product at a high deuteration rate (see Non-Patent Document 1).
 一方で、反応点の制御が容易な重水素化法として、ハロゲン化芳香族化合物のような脱離基を有する芳香族化合物を重水素化する方法が知られている。しかし、当該方法で問題になるのが、水素化の副反応であり、溶媒等に含まれる水素の反応系への混入による水素と重水素の競合、想定されないメカニズムの水素化反応の進行等により容易に重水素化率が低下する。 On the other hand, as a deuteration method in which the reaction point can be easily controlled, a method of deuterating an aromatic compound having a leaving group such as a halogenated aromatic compound is known. However, the problem with this method is the hydrogenation side reaction, due to the competition between hydrogen and deuterium due to the mixing of hydrogen contained in the solvent into the reaction system, the progress of the hydrogenation reaction by an unexpected mechanism, etc. The deuteration rate is easily reduced.
 これに対して、重水素化率を高めるために、高価な重溶媒等の重水素化合物を大量に用いる方法(非特許文献2~5参照)や、高価な遷移金属を基質に対して1モル当量以上使用する方法(非特許文献6および7参照)が知られているが、いずれもコスト面に問題がある。 On the other hand, in order to increase the deuteration rate, a method using a large amount of a deuterium compound such as an expensive heavy solvent (see Non-Patent Documents 2 to 5), or 1 mol of an expensive transition metal with respect to the substrate Although the method of using more than an equivalent (refer nonpatent literature 6 and 7) is known, all have a problem in cost.
 また、これらの方法の多くで、芳香環以外の不飽和部位(例えば、アルケン部位)も同時に重水素化されるなど選択性に乏しいという問題もある(非特許文献4、5および7参照)。 In many of these methods, there is also a problem that the unsaturated site other than the aromatic ring (for example, alkene site) is deuterated at the same time and the selectivity is poor (see Non-Patent Documents 4, 5 and 7).
 このように、コスト面と重水素化率との両方に優れた、芳香環への選択的な重水素導入法は知られていない。 Thus, there is no known method for selectively introducing deuterium into an aromatic ring, which is excellent in both cost and deuteration rate.
 一方、遷移金属触媒に用いられる様々なN-ヘテロ環状カルベン(NHC)型配位子が知られており、例えば、特許文献1には、クロスカップリングなどに有用な触媒の配位子前駆体が開示されている。しかし、特許文献1のようなカルベン配位子からなる遷移金属触媒を重水素化反応に用いた例は知られていない。 On the other hand, various N-heterocyclic carbene (NHC) type ligands used for transition metal catalysts are known. For example, Patent Document 1 discloses a ligand precursor of a catalyst useful for cross-coupling or the like. Is disclosed. However, an example in which a transition metal catalyst composed of a carbene ligand as in Patent Document 1 is used for a deuteration reaction is not known.

 本発明の目的は、コスト面と重水素化率との両方に優れた重水素化方法、さらには、芳香族化合物の脱離基(例えば、ハロゲン原子等)を選択的に重水素置換する方法、およびそれらに用いる重水素化触媒を提供することである。 An object of the present invention is to provide a deuteration method excellent in both cost and deuteration rate, and further a method of selectively deuterating a leaving group (such as a halogen atom) of an aromatic compound.
