Methyl 2-Deoxy-3,5-di-O-p-toluoyl-D-erythro-pentoside (CAS 4330-34-1)

Methyl 2-Deoxy-3,5-di-O-p-toluoyl-D-erythro-pentoside is a modified sugar derivative frequently used in carbohydrate research. The compound features protective p-toluoyl groups at the 3 and 5 positions, while the 2-deoxy modification eliminates the hydroxyl group at the C-2 position, providing a structural variation that enables detailed exploration of carbohydrate biosynthesis and glycosylation pathways. The methyl group at the anomeric position locks the sugar in a stable configuration, which helps to study glycosidase activities and glycosyltransferase enzyme interactions. This molecule′s specific modifications allow researchers to analyze enzyme specificity for different carbohydrate residues and to understand how structural variations influence the binding affinity of carbohydrate-active enzymes. Its structure aids in synthesizing various carbohydrate analogs, particularly those used for creating glycomimetics, which emulate the natural properties of oligosaccharides. In enzymatic assays, this derivative is valuable for probing enzyme mechanisms that require selective recognition of deoxy-sugars. Furthermore, by being a precursor in the synthesis of more complex glycans, it provides insight into the molecular basis of glycan-protein interactions. Overall, Methyl 2-Deoxy-3,5-di-O-p-toluoyl-D-erythro-pentoside is crucial in elucidating the structure-function relationship of deoxy sugars, contributing significantly to understanding carbohydrate enzymology and glycosylation research.
