Then, the quinoline ring system is constructed through the cyclization reaction in the molecule. This step may require basic conditions or specific catalysts to promote the formation of intra-molecular rings. The cyclized product is then oxidized to convert the group at the target position into a carbonyl group to obtain 4-oxo-8- (trifluoromethyl) -1,4-dihydroquinoline-3-carboxylic acid.
Another method can start from the heterocyclic compound and gradually build the target molecular structure through multi-step functional group conversion and cyclization. The heterocyclic ring is modified first, and a specific substituent is introduced, and then a series of reactions such as cyclization and functional group conversion are used to synthesize the final product.
There are many paths for synthesis, and it is necessary to carefully consider the reaction conditions, reagent selection, and product separation and purification in order to optimize the synthesis process and improve the yield and purity of the product.
