This compound is primarily used in organic synthesis and carbohydrate chemistry as a protected glycosyl donor. Its structure, featuring benzylidene and benzoyl protecting groups, makes it a valuable intermediate for the selective formation of glycosidic bonds. It is particularly useful in the synthesis of complex oligosaccharides and glycoconjugates, which are essential in the development of pharmaceuticals and bioactive molecules. The thio-glycoside moiety enhances its stability and reactivity, allowing for controlled glycosylation reactions. Additionally, it finds applications in the study of enzymatic processes and the development of glycosidase inhibitors, which are relevant in treating diseases like diabetes and viral infections.
