1-Isopropyl-2-oxo-1,2-dihydroquinoline-3-carboxylic acid, according to its name, its structure can be roughly analyzed. In this compound, the quinoline ring is its core structure. The quinoline ring is a nitrogen-containing heterocyclic ring formed by fusing the benzene ring with the pyridine ring.
In the 1,2-dihydroquinoline part, it can be seen that the double bond between the 1,2 positions of the quinoline ring has been hydrogenated to form a single bond, so it is a dihydro state. And the 2-oxo generation shows that there is a carbonyl group connected to the 2 positions, and the oxygen atom is connected to the carbon by a double bond, which gives the molecule a specific chemical activity.
Furthermore, 1-isopropyl indicates that the group attached to the 1-position carbon is isopropyl. The isopropyl group is a monovalent hydrocarbon group composed of three carbon atoms, which is branched like a branch.
As for the 3-carboxylic acid, there is a carboxyl group at the 3rd position of the quinoline ring. The carboxyl group is formed by linking the carbonyl group to the hydroxyl group. The structure of -COOH makes it acidic and can participate in many chemical reactions. < Br >

The synthesis method of 1-isopropyl-2-oxo-1,2-dihydroquinoline-3-carboxylic acid has been investigated throughout the ages. In the past, many scholars worked hard in the field of organic synthesis and created many methods to prepare such compounds.
One method is to use quinoline derivatives as starting materials. First take the appropriate quinoline and introduce the isopropyl group under specific reaction conditions. In this step, a suitable reagent and reaction environment need to be selected to ensure that the isopropyl group is precisely added to the specific position of the quinoline. The commonly used method, or the nucleophilic substitution reaction, uses a reagent containing isopropyl, such as isopropyl halide, to react with quinoline derivatives under the catalysis of alkali. The type and dosage of base, the reaction temperature and time are all key factors, and need to be carefully controlled to obtain the ideal yield and selectivity.
After the introduction of isopropyl, the oxidation reaction is continued to construct a 2-oxo structure. For this oxidation step, strong oxidants such as potassium permanganate and potassium dichromate, or specific transition metal catalyzed oxidation systems can be selected. During the reaction, pay attention to the tolerance of the substrate to avoid damage to the product due to excessive oxidation.
As for the construction of 3-carboxylic acid moiety, it can be achieved by carboxylation reaction on the basis of the above reaction. Or use carbon dioxide as the carboxyl source, and under the action of suitable metal catalysts and ligands, the substrate reacts with carbon dioxide to introduce carboxyl groups. In this process, the activity of the catalyst and the structure of the ligand have a great influence on the reaction process and results.
There is another way, using o-amino benzoic acid derivatives as the starting material. First, the cyclization reaction is carried out to construct a quinoline skeleton. This cyclization reaction may require conditions such as high temperature and strong acid to promote the formation of intra-molecular rings. After cyclization, isopropyl and 2-oxo structures are introduced in turn. The methods for introducing isopropyl and constructing 2-oxo structures are similar to those described above, but the reaction details may vary due to different starting structures.
In addition, there are strategies for gradually constructing target molecules by using other heterocyclic compounds as raw materials through multi-step transformation. Each method has its advantages and disadvantages, and it needs to be weighed according to actual needs, such as the availability of raw materials, the difficulty of the reaction, and the purity of the product.
