- the invention relates to a preparation method of a green visible light-catalyzed acetamide compound, which belongs to the technical field of organic synthesis.
- the amide bond is a basic functional group that widely exists in nature. According to statistics, about one-quarter of marketed drugs and two-thirds of drug candidates contain amide bonds. The formation of amide bonds is the most widely used organic chemical reaction in synthetic pharmaceutical chemistry. Therefore, it is particularly important to introduce amide bonds into organic molecules.
- the current methods for synthesizing amide compounds have some shortcomings, such as harsh reaction conditions, low yield, narrow substrate range, high reaction temperature, use of relatively expensive metal catalysts, and excessive acid-base additives.
- Olson's research group used pyridine as a base to achieve quantitative acetylation of acetamide and amine under thermal reaction conditions. However, this method requires high temperature and limited substrate range.
- the purpose of the present invention is to provide a green, environmentally friendly, energy-saving and efficient visible light catalytic method to synthesize acetamide compounds.
- the "light" in the photochemical reaction is a special reagent that can participate in the reaction. Metal complexes, organic dyes or semiconductors act as photosensitizers to trigger subsequent reactions.
- the photochemical reaction has the following characteristics: (1) The thermochemical reaction requires a large activation energy, which needs to be heated to a certain temperature for the reaction to occur; while the activation energy required for the photochemical reaction is very small, so at room temperature (2) Complex molecules often contain multiple active groups.
- thermochemical reaction to make one of the groups react, other groups need to be protected; and a photochemical reaction can specifically excite a group according to the position of the group in the molecule to trigger the reaction; (3)
- thermochemical reactions and photochemical reactions are different, so photochemical reactions can be used to synthesize products that cannot be synthesized by thermochemical reactions. Based on these properties of the photochemical reaction, the superiority of the present invention is obvious.

- the LED lamp is a white lamp; the wattage of the white lamp is 40W.
- reaction time is 4 to 12 hours.
- the preferred reaction time is 6 hours.
- the ketone is 2,3-butanedione, 1-phenylpropane-1,2-dione, 2,3-pentanedione, 2,3-hexanedione, and acetone.
- the ketone is 2,3-butanedione.
- the reaction is carried out in an organic solvent;
- the organic solvent is petroleum ether, 1,2-dichloroethane, 1,1,1-trichloroethane, 1,1,2-trichloroethane , nitromethane, acetonitrile, ethyl acetate, acetone, isopropanol or 95% ethanol.

- Photochemical reaction is a synthetic method with the goal of cleanliness, energy saving, and saving. Generally, photochemical reaction does not require activation energy, or only requires a small activation energy; at the same time, photochemical reaction can select the corresponding light source according to the absorption wavelength of each group in the molecule.
- the reaction mode is single in the existing technology for synthesizing bisamides ( Most of them are thermal reactions), the reaction substrate is narrow, the reaction yield is low, and excessive acid-base additives and metal catalysts are required.

Description
本发明涉及一种绿色的可见光催化的乙酰胺化合物的制备方法，属于有机合成技术领域。
酰胺键是一种广泛存在于自然界的基本官能团。据统计，约四分之一的上市药物与三分之二的候选药物含有酰胺键。酰胺键的形成是药物合成化学中应用最广泛的有机化学反应。因此，将酰胺键引入有机分子中显得尤为重要。通过文献调查发现，目前合成酰胺化合物的方法都存在一些不足之处，诸如反应条件苛刻，产率低、底物范围窄、反应高温、使用比较昂贵的金属催化剂、需要过量的酸碱添加剂等。例如：(1)
1937年，Olson课题组以吡啶作为碱，在热反应条件下实现乙酰胺和胺的定量乙酰化。但是，该方法需要较高的温度，底物范围比较局限。（参见：Olson,

Chloride and Pyridine.
J. Am. Chem. Soc.1937, 59, 10, 2003-2005.）；(2) 2019年，严国兵课题组以醋酸铜为催化剂，乙腈为溶剂，在80℃条件下实现富电子的苯胺与硫代乙酸盐合成乙酰胺。该方法底物范围非常局限，仅适用于一级富电子芳胺。（参见：Yan,

30, 06, 726-730.）；(3) 2019年，Asachenko等人报道了苯酯胺解法来合成酰胺。该方法需要采用易制爆的氢化钠为碱；反应需要130℃的高温；底物比较局限，仅能合成二级芳酰胺；反应时间较长；反应条件比较危险。（参见：zhevskiy, S. A.;

9, 3,
1536-1540.）；（4）2019年，吴晓峰课题组利用乙酰丙酮钯为催化剂，六羰基钼为酰基源，过量的碳酸钾为碱，在110℃的高温下实现了由芳基硼酸和硝基苯制备二级芳香族酰胺。该体系新颖，但是操作复杂，不仅需要昂贵的催化剂和酰基源，还需要加入复杂的配体结构，很难在工业上有所应用。（参见：Peng,

综上所述，目前报道的这些酰胺化合物的合成方法，反应过程比较繁琐，采用过量的碱、昂贵的金属催化剂以及酰基源、反应条件比较苛刻、反应模式比较单一（绝大多数为热反应）。因此，发展一种原料来源丰富、底物范围广、绿色、温和、高效、节能、环境友好的可见光催化的乙酰胺化方法显得尤为重要。
本发明的目的是提供一种绿色、环境友好、节能高效的可见光催化的方法来合成乙酰胺化合物，光化反应中的“光”是一种特殊的、能够参与反应的试剂，利用具有可见光吸收的金属配合物、有机染料或半导体作为光敏剂，引发后续的反应。与经典的热化学反应相比，光化学反应具有以下特点：（1）热化学反应需要较大的活化能，需要加热到一定温度反应才能发生；而光化学反应所需活化能很小，因此在室温下可以快速进行；（2）复杂的分子往往含有多个活性基团。热化学反应中要使其中某一个基团发生反应，需要将其它基团保护起来；而光化学反应可以根据基团在分子中的部位不同特定激发某一基团来引发反应的发生；（3）多数情况下热化学反应与光化学反应的产物不同，因此可利用光化学反应合成热化学反应不能合成的产物。基于光化学反应的这些性质，本发明的优越性显而易见，该反应体系中光源LED灯廉价易得、原料来源丰富、反应底物普适性广（一、二、三、级脂肪胺和芳香胺均兼容于该体系）、反应条件温和、无需任何酸碱添加剂、无催化剂、廉价的2,3-丁二酮作为反应原料，反应操作简便。
为达到上述发明目的，本发明采用的技术方案是：一种绿色的可见光催化的乙酰胺化合物的制备方法，在可见光照射下，以胺、酮为原料，反应制备乙酰胺化合物。
上述技术方案中，所述胺的化学结构式如下：
。
所述乙酰胺化合物的化学结构式如下：
。
上述化学结构式中，R
1选自萘基、7-氮杂吲哚基、烷基、苯并噻唑基、苯基以及单取代或多取代芳基，其中取代基为甲基、异丙基、叔丁基、甲氧基、叔丁基、硝基、羟基、氰基、酯基、苯基、氟、氯、溴、三氟甲基、三氟甲氧基、乙酰氧基、氨基、乙酰氨基、磺酰胺基等；R
2选自氢或者烷基。
上述技术方案中，所述可见光为LE灯光，LED灯为白灯、绿灯或者蓝灯；瓦数为18W～60W。优选的技术方案中，所述的LED灯为白灯；白灯的瓦数为40W。
上述技术方案中，反应的时间为4～12小时。优选的反应时间为6小时。
上述技术方案中，所述酮为2,3-丁二酮、1-苯基丙烷-1,2-二酮、2,3-戊二酮、2,3-己二酮、丙酮。优选的技术方案中，酮为2,3-丁二酮。
上述技术方案中，反应在有机溶剂中进行；所述有机溶剂为石油醚、1,2-二氯乙烷、1,1,1-三氯乙烷、1,1,2-三氯乙烷、硝基甲烷、乙腈、乙酸乙酯、丙酮、异丙醇或者95%乙醇。
上述技术方案中，酮的用量为胺摩尔量的5～7倍，优选6倍。
本发明采用廉价的脂肪胺或芳香胺为反应底物、经济易得的LED灯为光源、2,3-丁二酮作为原料、乙醇（95%）溶剂。本发明的反应在空气中进行。反应结束后，用无水硫酸钠干燥，用旋转蒸发仪除去溶剂、硅胶吸附，通过简单的柱层析即可得乙酰胺化合物。
由于上述技术方案的运用，本发明与现有技术相比具有下列优点：1.本文所使用的2,3-丁二酮来源广泛，采用绿色、温和、环境友好的可见光催化的模式制备乙酰胺化合物。光化学反应是以洁净、节能、节约为目标的合成方法，光化学反应一般不需要活化能，或者只需要很小的活化能；同时光化学反应可以根据分子中各个基团吸收波长的不同选择对应的光源，选择性地激发某一基团引发反应的发生；巧妙利用光化学反应往往可以大幅度缩短目标产物的合成路线，基于光化学反应的性质，与现有的合成双胺化物的技术中反应模式单一（大多数为热反应），反应底物窄，反应产率低，需要过量的酸碱添加剂和金属催化剂、反应条件苛刻相比（需要高温，强还原剂，高能耗等），该发明具有反应底物范围广（一、二、三、级脂肪胺和芳香胺均兼容于该方法），无需脱水剂，反应条件简单，反应产率比较高，反应条件温和等特点。
2.本发明的技术不需要采用昂贵、预制备的酰基源，2,3-丁二酮可以直接参与反应，从而避免了操作上过于繁琐的问题。
3.本发明技术使用商业上可购买的芳香胺和脂肪胺底物作为反应原料，与现有的技术相比，底物无需合成，操作简便，与现有的技术相比，避免使用催化剂，尤其避免使用昂贵的铱、钌、钯等价格昂贵的金属。
下面结合实例对本发明作进一步描述：本发明采用了绿色、环保、温和、高效、节能的可见光催化的策略来合成乙酰胺化合物，在该发明中光源为经济易得的LED灯，反应底物胺与酮、有机溶剂皆商业化产品，可以直接购买获得，95%乙醇是指乙醇的质量百分数为95%，其余为水。本发明在无催化剂条件下，仅以酮、胺在有机溶剂中，可见光照射下反应，即可高效得到产物乙酰胺化合物。以下实验在空气中、室温下进行。
