Finally, a carboxyl group is introduced at the 3 position and converted into a carboxylic acid ester. This step can be accomplished with the help of suitable carboxylation reagents, such as carbon dioxide, halogenated carboxylic acid esters, etc., with the help of bases or catalysts.
The second method uses anthranilate and suitable carbonyl compounds as raw materials. The two first undergo a condensation reaction to construct the prototype of the quinoline ring. In this process, the amino group and the carbonyl group undergo a series of reactions such as condensation and cyclization to form an intermediate containing the quinoline structure. Next, a specific position of the intermediate, such as the 2 position, is oxidized to construct a carbonyl group. Finally, according to the desired product structure, the reaction conditions are adjusted, and other parts are modified to obtain the target 2-oxo-1,2-dihydroquinoline-3-carboxylic acid ester.

In this series of reactions, the precise control of reaction conditions, such as temperature, solvent, catalyst type and dosage, have a great impact on the yield and purity of the product. Different reaction paths are suitable for different scenarios. In actual preparation, it is necessary to comprehensively consider factors such as raw material availability, cost, difficulty of reaction operation and product quality, and make careful choices.
