二芳基硫醚类衍生物及其制备方法Diaryl sulfide derivatives and preparation method thereof

技术领域technical field

本发明涉及有机合成领域,且特别涉及一种二芳基硫醚类衍生物及其制备方法。The invention relates to the field of organic synthesis, and in particular to a diaryl sulfide derivative and a preparation method thereof.

背景技术Background technique

二芳基硫醚类衍生物广泛应用于医药、农业、染料、轻化用品、高聚材料等领域。一些具有生物活性的二芳基硫醚化合物在医药分子研究中展示了其独特的药理作用,例如二芳基硫醚化合物I被用作白细胞对抗药(LFA-1),化合物II是作为一种微管蛋白抑制剂能够显著抑制人类MCF-7乳房癌细胞的生长。Diaryl sulfide derivatives are widely used in medicine, agriculture, dyes, light chemical products, high polymer materials and other fields. Some biologically active diaryl sulfide compounds have demonstrated their unique pharmacological effects in the study of medical molecules. For example, diaryl sulfide compound I is used as a leukocyte antidote (LFA-1), and compound II is used as a Tubulin inhibitors can significantly inhibit the growth of human MCF-7 breast cancer cells.

随着有机硫化合物在合成中的广泛应用,近年来有机硫化合物在有机合成中的应用得到普遍重视。二芳基硫醚类化合物的合成路径引起了无数有机合成工作者的积极思考,并且得出了一些很有效的方法。通过芳环碳与硫原子的C―S偶联是二芳基硫醚类化合物合成的主要途径,过渡金属催化被广泛应用于二芳基硫醚类化合物的C―S偶联反应。With the wide application of organosulfur compounds in synthesis, the application of organosulfur compounds in organic synthesis has received widespread attention in recent years. The synthetic route of diaryl sulfide compounds has aroused the active thinking of countless organic synthesis workers, and some very effective methods have been obtained. The C—S coupling reaction of aromatic ring carbon and sulfur atom is the main way to synthesize diaryl sulfides, and transition metal catalysis is widely used in the C—S coupling reaction of diaryl sulfides.

过渡金属催化合成二芳基硫醚的三种主要方法中,钯类催化剂较高的毒性、不菲的价格、及对含磷配体的依赖制约了其在工业化生产中应用。铜、镍类催化剂也需在加入配体及其它添加剂的情况下才能发挥催化作用,而额外试剂的加入必然也对反应条件及原料分子结构中基团的兼容性起了一定的限制作用。因此,高效性、产率高、具有原子经济性的绿色合成方法在C―S偶联反应制备二芳基硫醚类化合物的研究中成为了一个新的导向。Among the three main methods for the synthesis of diaryl sulfides catalyzed by transition metals, the high toxicity, high price, and dependence on phosphorus-containing ligands of palladium catalysts restrict their application in industrial production. Copper and nickel catalysts also need to add ligands and other additives to play a catalytic role, and the addition of additional reagents must also limit the reaction conditions and the compatibility of the groups in the molecular structure of the raw materials. Therefore, the green synthesis method with high efficiency, high yield and atom economy has become a new direction in the research on the preparation of diaryl sulfide compounds by C—S coupling reaction.

本发明实施例还提供一种二芳基硫醚类衍生物的制备方法:The embodiment of the present invention also provides a preparation method of diaryl sulfide derivatives:

具体的反应式为:The specific reaction formula is:

具体的合成包括以下步骤:Concrete synthesis comprises the following steps:

S1、制备中间体;S1, preparation of intermediates;

在无水无氧体系中,将二炔类化合物和烃基炔溴加入到无水乙腈中,而后加入过渡金属催化剂和有机碱混合并在室温下搅拌12-20小时反应得到中间体。In an anhydrous and oxygen-free system, add a diacetylenic compound and an alkyne bromide into anhydrous acetonitrile, then add a transition metal catalyst and an organic base, mix and stir at room temperature for 12-20 hours to obtain an intermediate.

采用无水无氧体系是为了保证过渡金属催化剂的活性,若反应体系中存在水或者氧气将会使得过渡金属催化剂失去活性,进而不能合成得到中间体,影响二芳基硫醚类衍生物的生成。而采用过渡金属作为催化剂降低了反应所需的能量,使得反应能够顺利进行。优选地,所用的二炔类化合物为碳原子桥连的二炔类化合物或者是氮原子桥连的二炔类化合物。The anhydrous and oxygen-free system is used to ensure the activity of the transition metal catalyst. If water or oxygen exists in the reaction system, the transition metal catalyst will lose its activity, and then the intermediate cannot be synthesized, which will affect the formation of diaryl sulfide derivatives. . The use of transition metals as catalysts reduces the energy required for the reaction, allowing the reaction to proceed smoothly. Preferably, the diynes used are carbon-atom-bridged diynes or nitrogen-atom-bridged diynes.

优选地,过渡金属催化剂为Pd(PPh3)2Cl2和CuI,Pd(PPh3)2Cl2和CuI的物质的量之比为2.8-3.2:1。采用Pd(PPh3)2Cl2和CuI混合作为催化剂时,Pd(PPh3)2Cl2作为催化剂,而CuI作为助催化剂,提升催化剂的效能,加快反应速率,提高产率。二者使用的比例保证了催化效果,进一步地加快反应速率,减少副产物。Preferably, the transition metal catalyst is Pd(PPh 3 ) 2 Cl 2 and CuI, and the ratio of the amounts of Pd(PPh 3 ) 2 Cl 2 to CuI is 2.8-3.2:1. When Pd(PPh 3 ) 2 Cl 2 and CuI are used as the catalyst, Pd(PPh 3 ) 2 Cl 2 is used as the catalyst, and CuI is used as the co-catalyst to improve the efficiency of the catalyst, accelerate the reaction rate and increase the yield. The ratio of the two ensures the catalytic effect, further accelerates the reaction rate and reduces by-products.

优选地,有机碱为胺类化合物,例如甲胺、乙胺、丙胺、丁胺、戊胺、二乙胺、二丙胺、二丁胺、二戊胺、二己胺、三乙胺等。进一步优选地有机碱为三乙胺。三乙胺可以反应生成的溴化氢反应,进而促进整个反应平衡向生成物方向进行。Preferably, the organic base is an amine compound, such as methylamine, ethylamine, propylamine, butylamine, pentylamine, diethylamine, dipropylamine, dibutylamine, dipentylamine, dihexylamine, triethylamine and the like. It is further preferred that the organic base is triethylamine. Triethylamine can react with the generated hydrogen bromide, and then promote the entire reaction equilibrium to the direction of the product.

进一步优选地,二炔类化合物、烃基炔溴、过渡金属催化剂和有机碱物质的量之比为1:2-3:0.03-0.05:2-5,二炔类化合物在无水乙腈中的浓度为0.5-0.8mol/L。在该优选值范围内进行的反应速率快,产率高,副反应少。Further preferably, the ratio of the amount of diacetylenic compound, hydrocarbyl alkyne bromide, transition metal catalyst and organic base substance is 1:2-3:0.03-0.05:2-5, the concentration of diacetylenic compound in anhydrous acetonitrile It is 0.5-0.8mol/L. The reaction rate carried out within this preferred value range is fast, the yield is high, and side reactions are few.

S2、纯化中间体;S2, purification of intermediates;

纯化中间体,是去除中间体内可能含有的杂质,减少杂质对后续反应的影响,同时减少二芳基硫醚类衍生物内可能含有的杂质。甚至中间体内含有的杂质可能导致后续不能反应生成得到二芳基硫醚类衍生物。Purifying the intermediate is to remove the impurities that may be contained in the intermediate, reduce the impact of the impurities on the subsequent reaction, and reduce the impurities that may be contained in the diaryl sulfide derivatives. Even the impurities contained in the intermediate may lead to the inability to generate diaryl sulfide derivatives in the subsequent reaction.

纯化是将二炔类化合物、烃基炔溴、无水乙腈、过渡金属催化剂和有机碱混合并反应得到的第一反应液首先采用质量百分比为15%的盐酸溶液洗涤去除有机碱,而后再用质量百分比为10%的碳酸氢钠溶液洗涤去除盐酸溶液中的盐酸,再用饱和食盐水洗涤以去除碳酸氢钠。接着采用乙酸乙酯萃取洗涤后第一反应液,除去水相。然后使用无水硫酸镁干燥萃取后得到的有机相。干燥后使用旋转蒸发仪旋蒸以去除有机相中的有机溶剂。最后再用柱层析纯化旋蒸后得到物质,得到纯度高的中间体。其中,柱层析采用的淋洗剂为乙酸乙酯与石油醚的混合液,混合液中乙酸乙酯与石油醚的体积比为1:40-60。采用上述的淋洗液能够良好的分离中间体和杂质。Purification is to mix and react the first reaction solution obtained by diacetylenic compound, alkyne bromide, anhydrous acetonitrile, transition metal catalyst and organic base, first use 15% by mass percentage of hydrochloric acid solution to remove the organic base, and then use mass percent Wash with 10% sodium bicarbonate solution to remove hydrochloric acid in hydrochloric acid solution, and then wash with saturated brine to remove sodium bicarbonate. Then, ethyl acetate was used to extract and wash the first reaction liquid, and the water phase was removed. The organic phase obtained after extraction was then dried using anhydrous magnesium sulfate. After drying, use a rotary evaporator to remove the organic solvent in the organic phase. Finally, column chromatography is used to purify the substance obtained after rotary evaporation to obtain an intermediate with high purity. Wherein, the eluent used in column chromatography is a mixture of ethyl acetate and petroleum ether, and the volume ratio of ethyl acetate and petroleum ether in the mixture is 1:40-60. The above-mentioned eluent can be used to separate intermediates and impurities well.

S3、合成得到二芳基硫醚类衍生物粗品;S3, synthesize and obtain the crude product of diaryl sulfide derivatives;

在90-115℃条件下,将中间体和芳基二硫醚在甲苯溶剂中搅拌混合反应16-24小时,得到二芳基硫醚类衍生物粗品。温度为影响该反应的重要因素,若温度高于或低于该温度范围则生成物质的结构将发生变化,得不到本发明所需的二芳基硫醚类衍生物。Under the condition of 90-115° C., the intermediate and aryl disulfide are mixed and reacted in toluene solvent for 16-24 hours to obtain the crude product of diaryl sulfide derivatives. Temperature is an important factor affecting the reaction. If the temperature is higher or lower than the temperature range, the structure of the resulting substance will change, and the desired diaryl sulfide derivatives of the present invention cannot be obtained.

优选地,中间体与芳基二硫醚的物质的量之比为1:0.6-1.2。甲苯作为溶剂时,中间体在甲苯中的浓度是0.1-0.3mol/L。在该优选值范围内进行的反应速率快,产率高、副产物少。Preferably, the substance amount ratio of the intermediate to the aryl disulfide is 1:0.6-1.2. When toluene is used as a solvent, the concentration of the intermediate in toluene is 0.1-0.3mol/L. The reaction rate carried out within this preferred value range is fast, the yield is high, and by-products are few.

S4、纯化二芳基硫醚类衍生物粗品;S4, purifying the crude product of diaryl sulfide derivatives;

反应得到的二芳基硫醚类衍生物粗品内含有杂质,这些杂质会影响对二芳基硫醚类衍生物结构的鉴定或者影响后续的使用。因此,需要对其进行进一步地纯化。The crude product of diaryl sulfide derivatives obtained from the reaction contains impurities, which will affect the identification of the structure of the diaryl sulfide derivatives or affect the subsequent use. Therefore, it needs to be further purified.

将制备得到的二芳基硫醚类衍生物粗品即第二反应液经过去离子水洗涤后,用乙酸乙酯萃取,用无水硫酸镁干燥萃取液。过滤后,用旋转蒸发仪蒸干萃取液中溶剂。二芳基硫醚类衍生物粗品用柱层析的方法分体提纯,柱层析的淋洗剂为乙酸乙酯与石油醚的混合液,混合液中乙酸乙酯与石油醚的体积比为1:30-60,柱层析产率约为80%。The prepared crude diaryl sulfide derivatives, that is, the second reaction solution, was washed with deionized water, extracted with ethyl acetate, and the extract was dried with anhydrous magnesium sulfate. After filtration, the solvent in the extract was evaporated to dryness with a rotary evaporator. The crude product of diaryl sulfide derivatives is separated and purified by column chromatography.
