ethyl methyl 1,4-dihydro-2,6-dimethyl-4-(meta-nitrophenyl)-3,5-pyridinedicarboxylate

Eh! Now there is a chemical name "ethyl + methyl + 1,4 - dihydro - 2,6 - dimethyl - 4 - (meta - nitrophenyl) - 3,5 - pyridinedicarboxylate", to know its chemical structure. This name is complicated, detailed analysis. "Ethyl" is ethyl, "methyl" is methyl, "1,4 - dihydro" Table 1,4 - dihydro structure, "2,6 - dimethyl" refers to 2,6-bit dimethyl, "4 - (meta - nitrophenyl) " shows 4-bit nitrophenyl, "3,5 - pyridinedicarboxylate" is 3,5-bit pyridine dicarboxylate structure. From this, the chemical structure should be based on the pyridine ring as the core, the 1 and 4 positions are in the dihydrogen state, the 2 and 6 positions are connected to a methyl group, the 4 positions are connected to a nitrophenyl group, and the 3 and 5 positions are diformate groups, which are connected to ethyl and methyl groups respectively. Although this structure is complex, it can be explained by the chemical nomenclature.

The method of preparing ethyl methyl 1,4 - dihydro - 2,6 - dimethyl - 4 - (meta - nitrophenyl) - 3,5 - pyridinedicarboxylate is essential for organic synthesis. This compound has the structure of pyridine dicarboxylate, and the preparation method follows the path of organic reaction.
The common method can be started by a suitable starting material through a condensation reaction. For example, ketones and aldose compounds with suitable substituents are selected, and the condensation reaction is carried out under the action of a basic catalyst to build the basic structure of the pyridine ring. < Br >
First, take the ketone containing methyl, and the aldehyde containing m-nitrophenyl group, mix it in the alcohol solvent, and add an appropriate amount of alkali, such as sodium alcohol, etc. The alkali can take away the α-hydrogen of the ketone to generate a carbonegative ion. This carbonegative ion nucleophilic attacks the carbonyl carbon of the aldehyde, initiates a condensation reaction, and obtains a preliminary condensation product.
Then, based on this preliminary product, a carboxylic acid ester group is introduced. It can react with halogenated carboxylic acid esters in the presence of an appropriate base and catalyst. The halogen atom of the halogenated carboxylic acid ester has high activity, and the base prompts the activity check point of the preliminary product to attack the carbonyl carbon of the halogenated carboxylic acid ester. After nucleophilic substitution, the carboxylic acid ester group is introduced to obtain the target product ethyl methyl 1,4 - dihydro - 2,6 - dimethyl - 4 - (meta - nitrophenyl) - 3,5 - pyridinedicarboxylate.
During the reaction process, it is necessary to pay attention to the reaction temperature, time and the proportion of reactants. If the temperature is too high or too low, it can affect the reaction rate and product selectivity; if the time is too short, the reaction may not be fully functional, and if the time is too long, it may cause side reactions. The ratio of reactants is also critical, and the appropriate ratio At the same time, the separation and purification after the reaction are also heavy, and column chromatography and recrystallization are commonly used to obtain pure target products.
