The synthesis method of 6,7-dihydro-5H-pyrrolido [3,4-b] pyridinedione dianhydride is an important research in the field of organic synthesis. The method is as follows:
Starting material, select pyridine derivatives and suitable dianhydrides. If a specific substituted pyridine is used as the starting point, it has an active check point and can undergo nucleophilic substitution or cyclization with dianhydride. This reaction needs to be carried out in a suitable solvent, such as aprotic polar solvents, such as N, N-dimethylformamide (DMF), dimethylsulfoxide (DMSO), etc., to facilitate the dissolution of the reactants and the stability of the reaction intermediates.
The reaction process requires specific conditions. Suitable temperature is very important, often depending on the reactant activity and reaction type, or in the range of room temperature to high temperature, such as 50 ° C - 150 ° C. At the same time, a catalyst can be added to accelerate the reaction. For some nucleophilic substitution steps, alkali catalysts, such as potassium carbonate, sodium carbonate, etc., are selected to promote the nucleophilicity of pyridine derivatives and make it easier to react with dianhydride.
Reaction mechanism, the nitrogen atom or other active check points of pyridine derivatives first attack the nucleophilic carbonyl of dianhydride to form an intermediate. This intermediate is then rearranged and cyclized in the molecule to construct the structure of pyrrolido [3,4 - b] pyridinedione dianhydride. After that, the target product is isolated and purified. Column chromatography can be used to select a suitable eluent and separate it according to the polarity difference between the product and the impurities; or by recrystallization, a suitable solvent can be selected to make the solubility of the product change significantly with temperature, so as to achieve the purpose of purification. In this way, after multi-step operation, high-purity 6,7-dihydro-5H-pyrrolido [3,4-b] pyridinedione dianhydride can be obtained.
