| introduction | serine ammonia alcohol, that is, 2-amino-1, 3-propanediol, is a prochiral amino alcohol. Because its structure is similar to serine, it is usually called serine. Serinol has stable chemical properties, corrosive, hygroscopic and good water solubility. Natural serine was found early in the synthesis of helminthosporin toxin by sugarcane eye spot bacteria. Later, in the process of prokaryotic biosynthesis of rhizobia toxins such as plant pathogens Burkholderia, slow-growing soybean Rhizobium (Bradyrhizobiumjaponicum) and slow-growing Rhizobium elsen (Bradyrhizobiumelkanii), it was also discovered The existence of natural serine. |
| Application | Serinol generally exists in the form of a variety of chiral derivatives. Chiral compounds are widely used and occupy an extremely important position in the national economy and people's livelihood; the research, manufacture and use of chiral chemicals are of great significance to environmental protection and human health. Therefore, acylated serine ammonia alcohol and other serine ammonia chiral derivatives have become the focus and hot research recently. Acylated serinol, as an important second messenger in eukaryotes, is involved in regulating and managing various physiological processes such as cell growth, endocytosis, stress response and apoptosis, and plays an important role in the metabolism of eukaryotes. Like other chiral chemicals, serine and its derivatives also have great commercial value, and have more and more extensive applications in medicine, chemical industry and other fields. |
| use | serine ammonia alcohol and its derivatives have become a hot topic in the field of organic compound research. Nowadays, serine and its derivatives, as an important intermediate in chemical synthesis, are more widely used in medicine, chemical industry and other fields. An intermediate of iopamidol. It is the main raw material for the synthesis of the drug iopamidol The main raw material for iopamidol (iopamol) |
| preparation method | take 2.5g of serine with optical purity above 99.5%, dissolve it with 500g of pure water, and take the pre-prepared preferred but not limited commodity model D201 macroporous anion exchange resin, I .e. 100g of macroporous alkaline anion exchange resin, produced by Langfang new era chemical co., ltd. in Hebei province, China, into the above-mentioned serine aqueous solution, stir for 2.0h (static adsorption), the temperature is controlled at 5-10 ℃, the adsorbed resin is loaded into the column, and the ZnCl2 aqueous solution with a mass percentage concentration of 2% is used for reverse elution. The elution temperature is controlled at 15-20 ℃, and the elution speed is controlled at 5.0-6.0 vvh-1. As the elution progresses, the generated serinol precipitates from the aqueous solution. When there is no solid in the eluate, it contains serinol eluate. After solid-liquid separation, it is dried at 80 ℃ to obtain serinol 3g. Mass yield: 120%. |
| Production method | Catalytic hydrogenation of 5-oxime -1, 3-dioxane is reduced to 5-amino-1, 3 dioxane, and then hydrolyzed to obtain the product. |
