To prepare 4- (2,3-difluorobenzyl) -1,4-dihydro-2,6-dimethyl-3,5-p-dicarboxylic acid 3- (2-cyanoethyl) 5-methyl ester, the synthesis method is as follows:
First, use appropriate starting materials to construct a molecular skeleton through a step-by-step reaction. First, take a compound containing benzyl structure, and introduce 2,3-difluoro groups under specific reaction conditions. This step requires attention to the selectivity and condition control of the reaction, or specific catalysts and reaction solvents are required to precisely connect the fluorine atom to the 2,3 position of benzyl. < Br >
After the 2,3-difluorobenzyl derivative is obtained, the 1,4-dihydropyridine ring is constructed. Through multi-step reactions, various organic reaction reagents can be skillfully used to promote the condensation and cyclization of related molecules under suitable temperature, pH and other conditions, thereby forming the 1,4-dihydropyridine ring, and in this process, the dimethyl group is introduced at the 2,6 position on the ring.
Then, for the functionalization of the 3,5 position, the appropriate two-formic acid derivative is selected, and the 3- (2-cyanoethyl) 5-methyl ester group is connected to the 3,5 position through esterification. In this esterification reaction, attention should be paid to the proportion of reactants, the choice of catalyst, and the time and temperature of the reaction to improve the yield and purity of the reaction.
After each step of the reaction, purification methods such as column chromatography and recrystallization are required to remove impurities and improve the purity of the product. In this way, after carefully designed and operated reactions in multiple steps, the target product 4- (2,3-difluorobenzyl) -1,4-dihydro-2,6-dimethyl-3,5-p-dicarboxylic acid 3- (2-cyanoethyl) 5-methyl ester can be obtained. The synthesis path needs to be carefully planned, and the details of each step are related to the quality and yield of the final product.

4- (2,3-dioxybenzyl) -1,4-dioxy-2,6-diethyl-3,5-dioxy-dioxy-3- (2-oxyethyl) 5-methylfuran involves many chemicals, and the safety precautions are complicated. The following are one by one.
First of all, the components of this complex compound need to pay attention to their characteristics during operation. For example, 2,3-dioxybenzyl, because of its specific chemical activity, should be avoided in contact with strong oxidants, strong acids, etc. to prevent violent reactions. Be sure to wear suitable protective gloves and goggles during use, as it may irritate the skin and eyes. < Br >
1,4-dioxy has a relatively stable structure, but since it is often used as a solvent or reaction intermediate, it should be well ventilated in the use environment to prevent its volatilization and accumulation. Because if a large amount of steam is inhaled, it may affect the respiratory tract and nervous system.
2,6-diethyl moiety, the introduction of ethyl changes the molecular physical and chemical properties. Be careful to keep away from open flames and hot topics when operating. Due to the flammability of ethyl-containing compounds, storage should be placed in a cool, ventilated warehouse and stored separately from oxidants.
3 - (2-oxyethyl) moiety, oxyethyl has a certain reactivity. When synthesizing or using compounds containing this structure, strictly control the reaction conditions to avoid danger caused by overreaction. At the same time, because the group may affect the solubility and toxicity of the compound, wash it in time after contact.
5-methylfuran has a special odor and is flammable. Fireworks are strictly prohibited during use, and fire extinguishing facilities are equipped in the operating environment. Because it is a volatile organic compound, it is necessary to strengthen ventilation in a closed space to prevent the risk of explosion. And it may be toxic to aquatic organisms. Follow environmental regulations when handling waste containing this substance.
All operations involving this complex compound, from synthesis to storage, use and disposal, must strictly abide by chemical laboratory safety rules and relevant regulations. Before the experiment, fully understand the properties of each component and develop a comprehensive safety plan to ensure the safety of operators and the environment from pollution.
