A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 34213-34-8, Name is Methyl 2,3,4-Tri-O-acetyl-b-D-glucuronic Acid Methyl Ester, molecular formula is C14H20O10. In a Article£¬once mentioned of 34213-34-8, COA of Formula: C14H20O10
Photobromination of 2,3,4-tri-O-acetyl-1,6-anhydro-beta-D-glucopyranose gives the syrupy 6S (exo) bromide in high yield; further reaction leads to secondary bromination at this position.The monobromide reacts with methanol and thiophenol under conditions of kinetic control to give mainly the endo-methoxy and phenylthio derivatives formed by direct nucleophilic displacement, and from the latter the exo-methoxy acetal was obtained by a second nucleophilic substitution.Acetolysis of these compounds can lead to the coresponding exo-6-acetoxy ester or monocyclicproducts formed by opening of the five-membered rings.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.COA of Formula: C14H20O10, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 34213-34-8, in my other articles.
