Reference of 4928-88-5, New Advances in Chemical Research in 2021. Chemo-enzymatic cascade processes are invaluable due to their ability to rapidly construct high-value products from available feedstock chemicals in a one-pot relay manner. 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 13 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 0.079 g of benzenesulfonic acid was added thereto. The reaction mixture was reacted for 5 hours, while maintaining the temperature of the reaction mixture at 95+-5° C. And then, the reaction mixture was crystallized with 300.8 nm of methanol to give 3.08 g of 1-(2,3,5-tri-O-acetyl-beta-D-ribofuranosyl)-1,2,4-triazole-3-carboxylic acid methyl ester (yield: 80percent).
I am very proud of our efforts over the past few months and hope to Methyl 1H-1,2,4-triazole-3-carboxylate help many people in the next few years.
