Ethyl Methyl 2,3,4-tri-O-acetyl-beta-D-glucopyranosiduronate丨CAS 77392-66-6

Ethyl methyl 2,3,4-tri-O-acetyl-β-D-glucopyranosiduronate is primarily used as an intermediate in carbohydrate chemistry, glycoside synthesis, and pharmaceutical research. It serves as a protected sugar derivative for the preparation of complex oligosaccharides, glycosylated natural products, and drug conjugates. The acetyl-protected hydroxyl groups enable selective deprotection and glycosylation reactions, allowing precise assembly of glycosidic bonds. This compound is also employed in the synthesis of nucleotide-sugar analogs, glycosyl donors for enzymatic or chemical glycosylation, and as a building block for carbohydrate-based vaccines, diagnostics, and biologically active glycosides in medicinal chemistry.

The benefits of this compound include its stability, selective reactivity, and versatility in glycosylation chemistry. The acetyl groups protect reactive hydroxyl functionalities, enabling stepwise deprotection and controlled formation of glycosidic linkages. Its defined β-configuration ensures stereochemical precision, which is critical in synthesizing biologically active sugars. The compound is compatible with a variety of solvents and reaction conditions, allowing efficient transformations in multi-step synthetic sequences. Its stability and predictable reactivity make it a reliable intermediate for constructing complex carbohydrate architectures and glycosylated derivatives.
