The synthesis method of 4-oxo-7- (trifluoromethyl) -1,4-dihydroquinoline-3-carboxylic acid is based on the method of organic synthesis, and the Chang-Lai method is used together to achieve the same effect.
First, the aromatic amine can be started from an appropriate aromatic amine. First, the aromatic amine is condensed with an enone compound containing trifluoromethyl. This reaction requires the selection of a suitable solvent, such as an aprotic organic solvent, and the temperature is moderately controlled, about room temperature to mild heating range. By the power of a catalyst or an organic base, the nucleophilic addition of the two is promoted, and the enamine intermediate containing trifluoromethyl is initially obtained. Then, under acidic conditions, the intermediate undergoes intramolecular cyclization to form a 1,4-dihydroquinoline skeleton. Then, the 4-position is oxidized to a carbonyl group with an appropriate oxidizing agent, such as a high-valent metal salt, and the final target is 4-oxo-7- (trifluoromethyl) -1,4-dihydroquinoline-3-carboxylic acid.
Second, quinoline derivatives can also be used as raw materials. First, trifluoromethyl is introduced into the 7-position of the quinoline ring, which can be achieved by electrophilic substitution reaction with a reagent containing trifluoromethyl, such as a trifluoromethylation reagent, under suitable catalyst and reaction conditions. Subsequently, the selective reduction of the 1,4 positions can be carried out, and the method of catalytic hydrogenation can be selected. The noble metal catalyst is used to control the hydrogen pressure and temperature to obtain the structure of 1,4-dihydroquinoline. Finally, the carboxylation reaction at the 3 positions is carried out, and the carboxyl group is used as the carboxyl source. With the assistance of organometallic reagents, the carboxyl group is successfully constructed, and the target product is obtained.
Third, a multi-component reaction strategy can also be adopted. The aromatic aldehyde, the active methylene compound containing trifluoromethyl and ammonia or amine compounds are used as raw materials in the same reaction system and reacted in series in multiple steps. First, the aldehyde is condensed with the active methylene compound, and then cyclized with the amine, and the 1,4-dihydroquinoline structure is formed Subsequent to the previous method, the specific position was oxidized and carboxylated to obtain 4-oxo-7- (trifluoromethyl) -1,4-dihydroquinoline-3-carboxylic acid. All synthesis methods have their own advantages and disadvantages, and need to be carefully selected according to the availability of raw materials, the ease of control of reaction conditions and the requirements of product purity.
