The synthesis of 4,5,6,7-tetrahydro-1H-pyrrolido (4,5-C) pyridine and its dicarboxylic anhydride is an important topic in the field of organic synthesis. To obtain this compound, the following steps can be followed:
First, to construct the pyridine ring structure. Suitable amines and carbonyl compounds are often used as starting materials to form rings by condensation reaction. For example, amines and dicarbonyl compounds with appropriate substituents are selected.

In this process, the precise control of reaction conditions is critical, and the temperature, catalyst type and dosage will all affect the reaction rate and selectivity.
The second is the introduction of tetrahydropyrrole ring. It can be achieved by cyclization reaction. The pyridine intermediate containing double bonds or active halogenated groups is used to interact with nucleophilic reagents to form intramolecular rings to construct the fused structure of tetrahydropyrrole ring and pyridine ring. In the meantime, the reaction solvent and reaction time should be carefully selected according to the characteristics of the substrate to ensure the smooth progress of the cyclization reaction.
The second step is the oxidation step, which oxidizes the obtained fused ring compound and converts it into the second target carboxylic acid anhydride. Suitable oxidizing agents can be selected, such as high-valent metal oxides or peroxides. During the oxidation process, attention should be paid to the reaction temperature and the drip acceleration of the oxidizing agent to avoid side reactions caused by excessive oxidation and affect the purity
The whole process of synthesis, separation and purification steps are also indispensable. After the reaction, the target product was isolated by extraction, column chromatography and other means, and the purity of the product was improved by fine operations such as recrystallization.
