The synthesis method of 6-ethyl-2-oxo-1,2-dihydropyridine-3-carboxylic acid has been known for a long time. In the past, many scholars have worked hard in the field of organic synthesis to obtain many methods.
One method is to use pyridine derivatives as starting materials. First choose a suitable pyridine, whose side chain has a modifiable group, and after alkylation, ethyl is introduced. This alkylation process requires careful selection of reagents and conditions. Halogenated ethane and base are often used for pyridine. The type and dosage of base are all related to the success or failure of the reaction and the yield. If potassium carbonate is used as a base, in a suitable organic solvent, heating and stirring, the activity of halogenated ethane, reaction temperature and time are all key variables.
Then, the specific position of the pyridine ring is oxidized. To obtain the structure of 2-oxo-1,2-dihydropyridine, the power of an oxidizing agent can be used. If a specific peroxide or a high-valent metal salt is used as an oxidizing agent, in an appropriate reaction system, the pH value and temperature can be adjusted to oxidize the nitrogen atom of the pyridine ring to a carbonyl group, and the structure of 1,2-dihydropyridine is formed. In this step of the reaction, the choice of oxidizing agent and the fine-tuning of the reaction conditions are crucial. If there is a slight difference, the product will not be pure. < Br >
Furthermore, the carboxyl group is introduced at the 3-position of the pyridine ring. It is often achieved by nucleophilic substitution or other related reactions with reagents containing carboxyl groups. For example, the halogen atom is introduced at the 3-position with a halogenated reagent, and then the carboxyl source reagent, such as carboxylate, undergoes nucleophilic substitution under the action of a suitable catalyst, and the halogen atom is replaced with a carboxyl group. In this process, the activity of the catalyst and the polarity of the reaction solvent all affect the efficiency and selectivity of carboxyl group introduction.
Another method is to use a chain compound containing a specific functional group as the starting material. The prototype of the pyridine ring is first constructed by cyclization reaction. This cyclization reaction is either an intramolecular condensation or a multi-step synergistic reaction. After cyclization, the groups on the ring are modified according to the above-mentioned similar methods, and ethyl, oxygen and carboxyl groups are introduced in turn. Each step of the reaction requires precise regulation of the reaction conditions according to the principles of organic chemistry to obtain pure 6-ethyl-2-oxo-1,2-dihydropyridine-3-carboxylic acid. The way of synthesis is full of thorns, but according to the scientific method, unremitting exploration can eventually obtain its exquisite method.
