Ethyl 2-oxo-6-(trifluoromethyl)-1,2-dihydropyridine-3-carboxylate

Ethyl 2-oxo-6- (trifluoromethyl) -1,2-dihydropyridine-3-carboxylate is an organic compound, and its chemical structure is composed of pyridine ring, ester group and trifluoromethyl group.
The pyridine ring is used as the core, and the nitrogen atom on the ring gives the structure specific electronic properties and reactivity. The 1,2-dihydropyridine part indicates that the pyridine ring is not completely conjugated, but there are two hydrogen atoms in the 1 and 2 positions. This unsaturated state makes the ring more likely to participate in chemical reactions, such as oxidation and reduction reactions.
Esteryl-COOEt is attached to the 3 position of the pyridine ring. The carbonyl group in the ester group is connected to the oxygen atom and has a polarity. It can participate in reactions such as hydrolysis, alcoholysis, and aminolysis. It is often used to construct new carbon-oxygen bonds or carbon-nitrogen bonds in the field of organic synthesis.
The trifluoromethyl-CF < 6 position is very characteristic. The electronegativity of the fluorine atom is extremely high, and the strong electron-absorbing effect of the trifluoromethyl group will significantly affect the electron cloud distribution of the pyridine ring, enhance the electrophilicity of the molecule, and make the specific position on the ring more susceptible to attack by nucleophiles. At the same time, the trifluoromethyl can also significantly change the physical and chemical properties of the molecule, such as improving fat solubility

The method of preparing ethyl 2-oxo-6- (trifluoromethyl) -1,2-dihydropyridine-3-carboxylic acid ester has been explored by Sanda in the past. Today, several common methods are described for you.
First, it is prepared by cyclization of alkenes and ammonia esters containing trifluoromethyl as raw materials. In an appropriate solvent, such as toluene or dichloromethane, add an appropriate amount of catalyst, such as organic base or metal salt. Control the reaction temperature and duration, and the ketenes and ammonia esters go through nucleophilic addition, molecular inner cyclization and other steps to finally obtain the target product. In this process, it is necessary to pay attention to the ratio of raw materials. If there is too much ketene, it may cause an increase in side reactions; if there is too much urethane, it may affect the yield. If the temperature is too high, the product may decompose; if the temperature is too low, the reaction rate will be slow.
Second, it is prepared from 2-halo-6- (trifluoromethyl) pyridine compounds and alcohols under basic conditions by ester exchange reaction. Using potassium carbonate or sodium hydroxide as a base, in an alcohol solvent, halo-pyridine and alcohol undergo nucleophilic substitution, and the halo atom is replaced by an oxy group to form a corresponding ester. In this reaction, the halogen atom activity of halo-pyridine is very important, and if the activity is high, the reaction is easy to proceed, but it is The strength and dosage of the base have a great influence on the reaction process and the purity of the product, and must be precisely controlled.
Third, the pyridine derivative containing trifluoromethyl is prepared by a series of reactions such as oxidation and esterification. First, the pyridine derivative is oxidized with a suitable oxidizing agent, such as potassium permanganate or hydrogen peroxide, to obtain the corresponding carbonyl compound, and then esterified with alcohol under acid catalysis. During the oxidation step, the concentration of the oxidizing agent and the reaction time need to be strictly controlled to prevent excessive oxidation. During esterification, the type and dosage of acid, reaction temperature and time are all related to the yield and purity of the product.
All these methods have advantages and disadvantages, and it is necessary to choose the best one according to the actual situation, such as the availability of raw materials, cost, product purity requirements, etc., in order to efficiently prepare ethyl 2-oxo-6- (trifluoromethyl) -1,2-dihydropyridine-3-carboxylate.
