The synthesis method of 4,5,6,7-tetrahydroquinopyridine-2,6-dione can be done according to the ancient method, with exquisite skills and steps.
First take suitable starting materials, such as aromatic compounds with specific substituents, which are the basis for synthesis. In the clean kettle, use alcohol as a solvent, add an appropriate amount of alkali, such as potassium carbonate, which can adjust the acid-base of the reaction and promote the progress of the reaction. Warm up to an appropriate degree, about 60-80 degrees Celsius, continue to stir, so that the raw materials are evenly mixed and interact. At this time, the raw material molecules follow the laws of chemistry, and condensation reactions gradually occur.
After the reaction has been carried out for a certain period of time, observe the reaction process by thin layer chromatography. If the raw material point gradually fades, the product point gradually becomes apparent and stabilizes, it can be seen that the reaction is nearly complete. Then, the reaction solution is cooled to room temperature, poured into an appropriate amount of water, extracted with an organic solvent, such as ethyl acetate, and extracted several times to enrich the product in the organic phase. Then dry the organic phase with anhydrous sodium sulfate to remove the moisture.
After that, distillation under reduced pressure to remove the organic solvent to obtain a crude product. The crude product is refined by column chromatography, and a suitable silica gel and eluent, such as petroleum ether and ethyl acetate, are mixed in a specific ratio to separate the product from impurities. With careful operation, the eluent containing the pure product is collected and the solvent is evaporated to obtain a pure 4,5,6,7-tetrahydroquinopyridine-2,6-dione.
Or according to the other method, aldodes, amines and dicarbonyl compounds are used as starting materials, and heated and refluxed in an organic solvent in the presence of an acidic catalyst, such as p-toluenesulfonic acid. During the reaction, the raw materials are condensed and cyclized with each other, and can also form this target product. After the reaction, the subsequent treatment is similar to the previous method. After extraction, drying, distillation, column chromatography and other steps, high purity can be obtained.
This method of synthesis requires the operator to be cautious, familiar with the principles of chemistry and reaction, and follow the order in order to obtain the desired result.
