The synthesis method of 7-methoxy-4-oxo-1,4-dihydroquinoline-3-carboxylic acid is described in ancient books, and there are about several ends.
First, it can be originated from suitable aromatic starting materials. If an aniline compound with a specific substituent is used as the starting point, it is first reacted with a suitable carboxylic acid derivative, such as an acyl halide or an acid anhydride, under specific conditions. This reaction may require a catalytic agent, such as Lewis acid, to promote its formation. The two combine to obtain an intermediate product. This intermediate product is cyclized. When it is cyclized, it may need to be heated or assisted by a specific alkali agent to rearrange and close the chemical bonds in the molecule to form the basic skeleton of quinoline. At this time, the 4-position or the untargeted oxygenated state can be oxidized to a 4-oxo state by appropriate oxidizing reagents, such as oxides or peroxides of a high-valent metal, and the 7-position methoxy group can be introduced in appropriate steps. This introduction may be obtained by the nucleophilic substitution reaction of halogenated alkanes and phenolic hydroxyl groups.
Second, there are also modifiers based on quinoline parent compounds. To find a suitable quinoline substrate, the 3-position, 7-position may have an easily transformable substituent first, and the 4-position may be a modifiable functional group. First, the 3-position is carboxylated with an appropriate carboxylation reagent, and the carboxyl group is introduced in a suitable reaction environment, such as in a specific organic solvent, under the catalysis of a base. Then, the 7-position substituent is adjusted to a methoxy group. This process may involve the fine operation of the substitution reaction. As for the 4-position, according to the characteristics of its existing functional groups, through suitable oxidation, reduction or other transformation reactions, the final structure of the 4-oxygen generation is obtained.
Third, there is also a multi-step series reaction method. First, a variety of small molecule raw materials, such as nitrogen-containing, oxygen-containing heterocyclic small molecules and compounds with aryl groups, are used in one pot, through carefully designed reaction sequences and conditions, such as different stages of temperature regulation, pH and reagent addition sequence, to gradually build a molecular skeleton. At the same time, each substituent is introduced accurately at the appropriate time, and the construction of 7-methoxy, 4-oxo and 3-carboxylic acids is completed in sequence, resulting in the synthesis of 7-methoxy-4-oxo-1,4-dihydroquinoline-3-carboxylic acids. Each of these methods has its own advantages and disadvantages. In practice, one should choose carefully according to the availability of raw materials, the difficulty of reaction, and the high or low yield.
