The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.10343-06-3, Name is 2,3,4,6-Tetra-o-acetyl-D-glucopyranose, molecular formula is C14H20O10. In a Patent£¬once mentioned of 10343-06-3, Safety of 2,3,4,6-Tetra-o-acetyl-D-glucopyranose
Synthetic Method of 20 (S)-Ginsenoside Rh2
A synthetic method of 20(s)-ginsenoside Rh2, that is 20(S)-protopanaxdiol-3-O-beta-D-glucopyranoside, is comprised of: protecting protopanaxdiol (A1) selectively first to produce monosubstituted protopanaxdiol (A2); and Glycosidating the monosubstituted protopanaxdiol with Glucopyranosyl donor in the presence of Lewis acid catalyst; Deprotecting the product; Then separating and purifying to obtain 20(s)-ginsenoside Rh2. The method is conducted under mild condition at low cost, and affords product with high stereoselectivity, high yield and purity. Therefore, the synthetic method of the present invention is suitable for production on large scale.
The reactant in an enzyme-catalyzed reaction is called a substrate. Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction.I hope my blog about 10343-06-3 is helpful to your research., Safety of 2,3,4,6-Tetra-o-acetyl-D-glucopyranose
