2,3,4,6-Tetra-O-acetyl-D-mannopyranosyl Fluoride (CAS 174511-17-2)

2,3,4,6-Tetra-O-acetyl-D-mannopyranosyl fluoride is a synthetic glycosyl donor widely used in glycoscience research. The compound features acetyl-protected hydroxyl groups, enhancing its stability while offering controlled reactivity during glycosylation reactions. Its fluorine-based leaving group is highly effective, providing the glycosyl fluoride donor with high selectivity in glycosidic bond formation. In carbohydrate synthesis, this compound is indispensable for constructing D-mannose-containing oligosaccharides and glycoconjugates. Its selective glycosylation capability enables researchers to create precise glycan linkages and explore the synthesis of complex polysaccharides. The fluoride group ensures high stereoselectivity, particularly for beta-mannosylation reactions, which can be challenging with other glycosyl donors. Scientists employ this compound for studying the stereochemical specificity of glycosyltransferases and glycosidases, offering insights into the enzymatic processing of mannose residues. The compound has been used in synthesizing glycan arrays that facilitate high-throughput screening of carbohydrate-binding proteins and in studying protein-glycan interactions in immune recognition and cell signaling pathways. The ability to generate structurally diverse glycosidic linkages using this donor is critical in exploring the roles of mannose in biological processes and for developing glycobiology probes that reveal carbohydrate-mediated recognition mechanisms.
