The synthesis method of 4,5-dihydro-4,5-dioxo-1H-pyrrolio [2,3-f] quinoline-2,7,9-tricarboxylic acid has been known for a long time and has been studied and improved by many talents. This synthesis method can be roughly divided into the following paths.
First, a compound containing a quinoline structure is used as the starting material. It is first halogenated at a specific location and introduced into a halogen atom to facilitate subsequent reactions. In the halogenation method, it is often necessary to select suitable halogenating reagents to control the temperature, time and solvent of the reaction, so that the halogen can be accurately connected to the target check point. Then, through the nucleophilic substitution reaction, the fragment containing the pyrrole structure is connected. In this step, the nucleophilic reagent with suitable activity needs to be selected to adjust the reaction conditions to achieve the desired substitution effect. Finally, through a series of reactions such as oxidation and carboxylation, the carboxyl group is constructed at a specific position to obtain the target product. The oxidation process, or strong oxidizing reagents, precisely control the degree of reaction to avoid excessive oxidation; the carboxylation step also requires careful selection of reagents and conditions to ensure that the carboxyl group is successfully introduced and the position is correct.
Second, it can be started from pyrrole compounds. First, the pyrrole is functionalized to introduce a group that can be coupled to the quinoline structure. Or by acylation, alkylation and other means, the specific hydrogen atom of pyrrole is substituted. Then, the condensation reaction is carried out with the compound containing quinoline precursors. At the time of condensation, the appropriate catalyst and reaction environment need to be selected to promote the smooth connection of the two. Subsequent operations such as oxidation, cyclization and carboxylation, the complete structure of the target molecule is gradually constructed, and the synthesis of 4,5-dihydro-4,5-dioxo-1H-pyrrolio [2,3-f] quinoline-2,7,9-tricarboxylic acid is achieved. In this path, each step of the reaction needs to be finely regulated to achieve the best yield and purity.
Third, there are also those who take the construction of heterocycles as the core strategy. First, the basic skeleton of pyrrolio-quinoline is constructed through a multi-step reaction. Or use an intramolecular cyclization reaction to cyclize a chain-like compound containing an appropriate linking group under suitable conditions to form a target heterocyclic structure. Then, the skeleton is oxidized and modified to introduce a carbonyl group, and then through a carboxylation reaction, a carboxyl group is introduced at a specific position to complete the synthesis of the product. The key to this path lies in the control of the conditions of the cyclization reaction, and the precise operation of subsequent oxidation and carboxylation.
All synthesis methods have their own advantages and disadvantages, and need to be carefully selected according to the actual availability of raw materials, the difficulty of the reaction, the purity and yield requirements of the target product, etc.

4,5-Dihydro-4,5-dioxo-1H-pyrrolio [2,3-f] quinoline-2,7,9-tricarboxylic acid is a special chemical substance. When storing and using, there are many points to pay attention to.
When storing, the first environment is dry. Because of its hygroscopicity, if it is in a humid environment, it is easy to absorb water vapor, causing its properties to change, and even affecting its chemical properties. It must be placed in a dry and well-ventilated place, and it must be contained in a sealed container to prevent water vapor from invading.
Temperature is also critical. Usually need to be stored in a cool place to avoid high temperature hot topics. Under high temperature, this substance may decompose or deteriorate, which will reduce its purity and stability. Generally speaking, the suitable temperature range may be 2-8 ° C, depending on its physicochemical properties and related instructions.
Light also affects it. The substance may be sensitive to light, exposed to long-term light, or cause luminescent chemical reactions to change its structure and properties. Therefore, when storing, it should be protected from light. You can choose an opaque container or store it in a dark place.
When using, safety protection must be comprehensive. The chemical properties of this substance may make it irritating and corrosive, and it can cause damage when it comes into contact with the skin, eyes or inhalation. When taking it, you need to wear protective clothing, protective gloves and goggles to ensure your own safety.
The operation process requires strict. Accurate measurement and use should be carried out according to the standardized process. Due to the special nature of the substance, the accuracy of the dosage has a great impact on the reaction results. And after use, properly dispose of the remaining substances and waste. According to relevant environmental protection regulations, it cannot be discarded at will to avoid polluting the environment.
Furthermore, the ventilation of the use place cannot be ignored. Good ventilation can discharge volatile gases in time, reduce the concentration of harmful gases, and reduce latent risks.
