Used as a glycosyl donor in carbohydrate synthesis, particularly in the preparation of complex oligosaccharides and glycoconjugates. The azido group serves as a protected form of an amine, allowing for further functionalization after glycosylation. The allyl and benzylidene protecting groups provide regioselective control during stepwise assembly of sugar chains. Commonly applied in the synthesis of biologically active molecules, including vaccine candidates and enzyme inhibitors, where precise stereochemistry and sugar linkage are critical. Its structure enables selective β-glycosidic bond formation, making it valuable in medicinal chemistry and glycobiology research.
