Methyl (S)-2-Amino-3-((S)-2-Oxopyrrolidin-3-Yl)Propanoate 4-Methylbenzenesulfonate

I am looking at your words, and I am inquiring about the chemical structure of methyl (S) -2-hydroxy-3- ((S) -2-oxypyrrolidine-3-yl) butyrate 4-methylbenzenesulfonate. This is a difficult problem in the field of organic chemistry, let me go through it in detail.
Methyl itself is a group composed of one carbon and three hydrogens, expressed as "-CH". (S) -2-hydroxy, which means that this compound has a hydroxyl group (-OH) at position 2, and its three-dimensional configuration is (S) type. This three-dimensional configuration is determined according to the Cahn-Ingold-Prelog rule, depending on factors such as atomic number.
3- ((S) -2-oxypyrrolidine-3-yl) moiety, pyrrolidine is a five-membered cyclic structure containing a nitrogen atom. 2-Oxygen represents a carbonyl group (C = O) at position 2 of pyrrolidine, while the (S) type stereo configuration shows its spatial arrangement. This pyrrolidine group is connected to position 3 of the main chain.
In the case of butyrate, the carboxyl group (-COOH) of butyric acid is esterified with alcohol to form an ester group (-COO-). In this structure, the hydrocarbon group of the butyric acid part is connected to the above-mentioned hydroxyl group and pyrrolidine group, and forms an ester group structure.
As for 4-methylbenzene sulfonate, the benzene sulfonate radical group (-SO
) is connected to 4-methylbenzene, and there is a methyl substitution at position 4 of 4-methylbenzene, that is, the benzene ring. The benzene sulfonate moiety is often combined with cations to balance charges, in this case, or with the cationic moiety of the above ester-containing structure.
Overall, this compound has a complex structure, fusing multiple functional groups and specific stereoconfigurations. A affects the properties of molecules based on different positions. Hydroxyl, carbonyl, ester, pyrrolidinyl, and benzene sulfonate can each develop their own capabilities to jointly construct this unique chemical structure, which makes it suitable for organic synthesis, medicinal chemistry, and other fields or has specific uses and properties.

The author of "Tiangong Kaiwu" is a novel of science and technology in ancient China. Its style of writing is simple and profound. Today there is a question: "What are the main uses of methyl (S) -2 -hydroxy-3- (S) -2 -oxo cyclopentyl-3-yl) butyrate benzyl 4-methylbenzenesulfonic anhydride?", and listen to me in detail.
Methyl (S) -2 -hydroxy-3- (S) -2 -oxo cyclopentyl-3-yl) butyrate benzyl 4-methylbenzenesulfonic anhydride is widely used in the field of medicine and chemical industry. In the pharmaceutical industry, it is often a key intermediate. Due to the delicacy of organic synthesis, complex drug molecular structures need to be built based on this substance. For example, the synthesis of some targeted anti-cancer drugs often uses their unique chemical structures to introduce specific functional groups, so that drug molecules can precisely act on cancer cell targets, improve efficacy and reduce side effects.
In the field of materials science, it also has its uses. In the research and development of new polymer materials, it can be used as an initiator or modifier for polymerization reactions. Using this substance to participate in the reaction can regulate the properties of polymer materials, such as improving the mechanical strength, thermal stability and chemical stability of the material. Make the material more suitable for aerospace, electronic devices and other fields with strict performance requirements.
Furthermore, in the manufacture of fine chemical products, such as fragrances, cosmetic additives, etc., it is also indispensable. Due to its unique chemical properties, it can give products a unique aroma or improve the physical characteristics of products, and enhance product quality and market competitiveness.
All of these show that the important use of methyl (S) -2 -hydroxy-3- (S) -2 -oxycyclopentyl-3-yl) butyric acid benzyl 4 -methylbenzenesulfonic anhydride in the chemical industry is a key factor in promoting industrial development.

To prepare methyl (S) -2-hydroxy-3- ((S) -2-oxypyrrolidine-3-yl) benzyl butyrate 4-methylbenzenesulfonate, the following method can be used:
Take (S) -2-hydroxy-3- ((S) -2-oxypyrrolidine-3-yl) butyric acid as the starting material, and esterify it with appropriate benzyl alcohol under the action of condensation reagents. Commonly used condensation reagents, such as dicyclohexyl carbodiimide (DCC) and 4-dimethylaminopyridine (DMAP), under this reaction condition, the two can be condensed to generate (S) -2-hydroxy-3- ((S) -2-oxypyrrolidine-3-yl) benzyl butyrate.
Subsequently, the resulting (S) -2-hydroxy-3- ((S) -2-oxypyrrolidine-3-yl) butyrate benzyl ester is reacted with p-toluenesulfonyl chloride in the presence of a base. The base can be selected as an organic base such as triethylamine. During this reaction, the sulfonyl group of p-toluenesulfonyl chloride will replace the hydrogen atom of the alcohol hydroxyl group, thereby generating the target product methyl (S) -2-hydroxy-3- ((S) -2-oxypyrrolidine-3-yl) benzyl butyrate 4-methylbenzenesulfonate.
The reaction process should pay attention to the control of reaction temperature, proportion of reactants and reaction time. The esterification reaction temperature should be maintained in a moderate range, generally between room temperature and 50 degrees Celsius. If the temperature is too high, side reactions may occur, which will affect the purity and yield of the product. During the p-toluene sulfonylation reaction, the amount of alkali should be precisely controlled. If the amount is too small, the reaction may be incomplete, the amount is too large, or other side reactions may be triggered. And the reaction process needs to be carried out in an anhydrous environment to avoid hydrolysis of p-toluenesulfonyl chloride and affect the reaction process. In this way, through this series of steps, the desired product can be obtained.

"Tiangong Kaiwu" is a scientific and technological masterpiece written by Song Yingxing in the Ming Dynasty, but it does not specify the purity requirements of "methyl (S) -2 -hydroxy-3- (S) -2 -oxo, pyrrole, alkane-3 -yl) propionate benzyl 4 -methylbenzene, sulfonate". These chemical substances are the products of fine synthesis of modern chemistry, and their purity requirements vary with the use.
If used in the field of medicine, it is related to the health and safety of patients, and the purity requirements are extremely strict. Pharmaceutical active ingredients need to be highly pure, and the impurity content must be extremely low to prevent impurities from causing adverse reactions. Generally speaking, the purity often needs to reach more than 99% or even higher to meet the medicinal standards.
Used in the field of materials science, if used as a synthetic raw material for special functional materials, it depends on the material performance requirements. If the material needs to have high stability and uniformity, the purity requirements are also high; if the effect on performance is small, the purity requirements may be appropriately relaxed.
Used in general chemical research, to explore the reaction mechanism, verify the theory, etc., the purity requirements are relatively flexible and can be adjusted according to the experimental purpose and method, or 95% or even lower purity can also meet the preliminary research needs.
In summary, the purity requirements for "methyl (S) -2 -hydroxy-3- (S) -2 -oxo, pyrrole, alkane-3 -yl) propionate benzyl 4 -methylbenzene, sulfonate" vary from application scenario to application scenario, and it is difficult to generalize, and it needs to be precisely defined according to the specific application.

Due to the characteristics of its chemical structure, it may react violently with certain substances. For example, avoid co-storage and co-transportation with strong oxidants, strong acids, strong alkalis, etc., otherwise it is very likely to cause serious safety accidents such as fires and explosions.
Fourth, whether it is a storage place or a transportation vehicle, it should be equipped with corresponding emergency treatment equipment and materials. In the event of an unexpected situation such as leakage, effective emergency treatment can be carried out in a timely manner. Such as adsorbents, which can be used to absorb leaking liquids; fire extinguishing equipment to deal with possible fires, etc.
