As an important bridge between the micro and macro material world, chemistry is one of the main methods and means for humans to understand and transform the material world. 4928-88-5, name is Methyl 1H-1,2,4-triazole-3-carboxylate, molecular formula is C4H5N3O2, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, below Introduce a new synthetic route.
EXAMPLE 15 A mixture of methyl 1,2,4-triazole-3-carboxylate (1.27 g, 0.01 mole) and beta-D-ribofuranosyl-1,2,3,5-tetraacetate (3.18 g, 0.01 mole) was melted and then 0.076 g of p-toluenesulfonic acid was added thereto. The reaction mixture was reacted for 3 hours, while maintaining the temperature of the reaction mixture at 95+-5° C. And then, the reaction mixture was crystallized with 20 ml of butanol to give 2.70 g of 1-(2,3,5-tri-O-acetyl-beta-D-ribofuranosyl)-1,2,4-triazole-3-carboxylic acid methyl ester (yield: 85percent).
The result showed that such a combination of chemo- and biocatalysis improved the catalytic yield more than two times compared with that of sole metal catalysis.I hope my blog about Methyl 1H-1,2,4-triazole-3-carboxylate is helpful to your research.
