Having gained chemical understanding at molecular level, chemistry graduates may choose to apply this knowledge in almost unlimited ways, as it can be used to analyze all matter and therefore our entire environment. Like 34213-34-8, Name is Methyl 2,3,4-Tri-O-acetyl-b-D-glucuronic Acid Methyl Ester. In a document type is Article, introducing its new discovery. COA of Formula: C14H20O10
In the chromate oxidation of a partially acylated sugar derivative to form the corresponding uronic acid, acyl migration to the primary alcohol group is a frequent cause of interference.In contrast to more commonly employed ester substituents, the O-levulinoyl group is far less prone to migration during oxidations with Jones reagent (chromic-sulfuric acids).Examples described here include levulinoyl at O-5 of acyclic and furanose derivatives, and both eq and ax O-4 of pyranose derivatives.It is also shown that, because of the acidity of the Jones reagent, use of the O-levulinoyl group, in combination with a primary p-anisyldiphenylmethyl substituent, permits sequential rapid hydrolysis of the latter and oxidation of the newly exposed alcohol group, which favors high overall yields.In contrast to its immobility in these oxidation reactions, when the leulinoyl group is on O-2 of an aldosyl bromide, it participates in 1,2-orthoester formation as rapidly as O-acetyl.The 2,3,4,6-tetraacetate of either anomer of methyl D-glucopyranoside is oxidized to a uronic acid in moderate yield, by chromic acid in 5:1 acetic acid-water.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.COA of Formula: C14H20O10. This is the end of this tutorial post, and I hope it has helped your research about 34213-34-8
