Abstract
Description
Technical Field
[0001] This invention relates to a method for synthesizing deuterium-labeled substances containing deuterium atom structural units under normal pressure, belonging to the field of organic synthesis technology. Background Technology
[0002] Deuterium is a stable, non-radioactive isotope of hydrogen, exhibiting chemical properties comparable to hydrogen in certain reactions. Deuterated compounds have wide applications in various research fields, including isotope labeling, quantitative analysis, and pharmacokinetic analysis. Therefore, compounds containing deuterium labeling represent an important class of structural units, and the introduction of this group has significant research implications.
[0003] The promising prospects of deuterated drug molecules have attracted the attention of numerous research groups. Among these methods, the dehalogenation of aryl halides has become the preferred method for preparing deuterated products. With the development of cross-coupling reactions, the introduction of transition metals has facilitated the breaking of the CX bond. Improvements in dehalogenation reactions over the past five years have primarily involved using deuterated water as the deuterium source to achieve relatively mild dehalogenation of halides under photocatalytic or electrocatalytic conditions. For example, L. Lu, H. Li, Y. Zheng, F. Bu, A. Lei, Facile and Economical Electrochemical Dehalogenative Deuteration of (Hetero)Aryl Halides. CCS Chem., 2021, 3, 2669. provides a detailed report on the synthesis methods of these compounds. However, these methods have the following limitations: 1. Limited substrate applicability; 2. Use of expensive platinum as an electrode; 3. Incompatibility with sensitive substituents containing active hydrogen, etc.
[0004] Furthermore, CN115745720A discloses a method for the dehalogenation and deuteration of deuterated aromatic compounds. This method uses aromatic compounds as raw materials, palladium acetate, palladium chloride, palladium bromide, and palladium iodide as catalysts, heavy water, deuterated methanol, deuterated ethanol, and deuterated acetone as deuterium source reagents, and magnesium, aluminum, and zinc as reducing agents. The reaction is carried out by mechanical grinding. After the reaction, the product is separated and purified to obtain the deuterated compound. This method has advantages such as high operability, good deuteration effect, fast reaction rate, and solvent-free operation. However, this method has disadvantages such as poor functional group compatibility, and cannot perform dehalogenation and deuteration reactions on aryl halides containing active hydrogen functional groups such as amino and hydroxyl groups. Also, it mainly focuses on the dehalogenation and deuteration process of aryl bromide raw materials, with few reports on aryl chlorides. CN114054046A discloses the preparation and application of an Au / CdS composite photocatalytic material, using sodium sulfite as a sacrificial agent, water and acetonitrile (v:v = 1:1) as solvents, and Au / CdS as a catalyst, to carry out a deuteration reaction under an inert atmosphere and light irradiation (λ > 400 nm). CN115322065A discloses a method for the industrial production of deuterated pharmaceutical intermediate D using a combination of supported nickel and organic base catalysis. However, the use of relatively hazardous deuterium gas as a deuterium source poses safety challenges, and the high price of deuterium gas greatly limits the industrial-scale application of this method; furthermore, this method can only achieve deuteration at specific sites, which is limited compared to dehalogenation deuteration. CN111233716A discloses a nickel-catalyzed method for the preparation of α-deuterated chiral sulfonamide compounds. However, the main limitation of this method is that it can only perform deuteration at specific sites of the imine structure, resulting in a narrow substrate range for the deuteration reaction. Summary of the Invention
[0005] In view of the aforementioned state of the prior art, the technical problem to be solved by the present invention is to overcome the shortcomings of the prior art, which generally involves deuteration reactions under high conditions such as heating or high pressure, resulting in a narrow range of substrates that can be selected for deuteration reactions, and the need to further improve the deuteration rate and yield.

[0019] According to the present invention, preferably, the deuterium-labeled compound (II) is selected from at least one of the following compounds:
[0020]
[0021] The beneficial effects of this invention are as follows:
[0022] 1. This invention uses ethylene glycol dimethyl ether-nickel dichloride as a catalyst, enabling the reaction of aryl chlorides with deuterated water to generate deuterated products under nitrogen atmosphere, ambient temperature and pressure. The reaction conditions are simple and mild. Furthermore, it allows for a wider range of substrate choices and uses inexpensive nickel as a catalyst, making it more economically valuable than previously reported methods.
[0023] 2. Compared with traditional synthesis methods, the method of the present invention has many advantages such as high yield, simple conditions, low waste discharge, simple reaction equipment, and easy industrial production. Detailed Implementation
[0024] The present invention provides a method for synthesizing deuterium-labeled substances containing deuterium atom structural units, comprising the following steps:
[0025] Aryl chloride (I) was mixed with deuterated water in an organic solvent, and the catalyst ethylene glycol dimethyl ether-nickel dichloride and the ligand 2,9-dimethyl-1,10-o-phenanthroline were added. The mixture was then reacted in the presence of zinc powder and under nitrogen protection to prepare deuterium-labeled compound (II).
[0026] (I) is for Where R 1 It is selected from hydrogen, alkyl, alkoxy, aromatic, substituted aromatic, heterocyclic aromatic, hydroxyl, amino, aldehyde, ester, carbonyl, and / or cyano.
[0027] According to the present invention, the deuteration reaction is carried out in an organic solvent. The highest deuteration rate and yield are achieved with N,N-dimethylacetamide, followed by N,N-dimethylformamide. The yields and deuteration rates of N-methylpyrrolidone and dimethyl sulfoxide are lower than those of the aforementioned two solvents. Furthermore, these solvents are readily soluble in water, offering advantages over existing technologies such as simplified operation and purification.
[0028] In one or more preferred embodiments, the organic solvent is dimethyl sulfoxide, N,N-dimethylformamide, N,N-dimethylacetamide, or N-methylpyrrolidone.
[0029] According to the present invention, the deuteration reaction can be carried out at room temperature and pressure, without the need for higher temperatures and pressures. Compared with the prior art, the reaction conditions are milder. At higher temperatures and pressures, no significant increase in reaction yield and deuteration rate was observed.
[0030] In one or more preferred embodiments, the reaction temperature is 15°C to 40°C, preferably 20°C to 35°C.
[0031] In one or more preferred embodiments, the reaction pressure is 1 atm to 3 atm, preferably 1 atm to 1.5 atm.
[0032] According to the present invention, the catalyst for the deuteration reaction is ethylene glycol dimethyl ether-nickel dichloride, with 2,9-dimethyl-1,10-o-phenanthroline as a ligand. As a catalyst, ethylene glycol dimethyl ether-nickel dichloride coordinates and activates with 2,9-dimethyl-1,10-o-phenanthroline in the reaction system to form a key nickel intermediate, which will be used to catalyze subsequent reaction processes.
[0033] According to the present invention, zinc powder is used as a reducing agent in the reaction system to complete the reduction process of the nickel catalyst.
[0034] According to the present invention, regarding the proportions of the various materials, a higher deuteration rate and yield can be obtained when the molar ratio of aryl chloride to deuterated water is 1:5. When the molar ratio of deuterated water is further increased, the deuteration rate and yield of the reaction will not show a significant increase. Furthermore, when the molar ratio of ethylene glycol dimethyl ether-nickel dichloride, 2,9-dimethyl-1,10-o-phenanthroline, or zinc powder is further increased, the deuteration rate and yield of the reaction will not change significantly.
[0035] In one or more preferred embodiments, the molar ratio of aryl chloride to deuterated water is 1:3 to 1:20, preferably 1:5 to 1:10.
[0036] In one or more preferred embodiments, the molar ratio of aryl chloride to ethylene glycol dimethyl ether-nickel dichloride is 1:1 to 20:1, preferably 5:1 to 20:1.
[0037] In one or more preferred embodiments, the molar ratio of aryl chloride to 2,9-dimethyl-1,10-o-phenanthroline is 1:1 to 10:1, preferably 1:1 to 5:1.
[0038] In one or more preferred embodiments, the molar ratio of aryl chloride to zinc powder is 1:1 to 1:5, preferably 1:2 to 1:3.
[0039] According to the present invention, the above-mentioned deuteration reaction system has better operability due to its milder reaction temperature and simpler reaction conditions compared to previous reports. Since the relevant reaction proceeds via a reductive coupling mechanism, the reaction route has good compatibility with substituent groups.
[0040] According to the present invention, after the reaction is completed, the process further includes quenching the reaction and separation and purification steps:
[0041] The reaction was quenched by adding ethyl acetate, washed with brine, and the organic phase was separated. The aqueous phase was extracted with ethyl acetate, the organic phases were combined, and the target product was obtained by column chromatography.
[0042] The present invention will be described in detail below through specific embodiments, but is not limited thereto.
[0043] The room temperature mentioned in the embodiment is 15℃~35℃, and the atmospheric pressure is 1atm.
