Used in organic synthesis as a chiral building block for the preparation of complex natural products and pharmaceuticals. Serves as a key intermediate in the synthesis of antiviral and anticancer agents due to its sugar-like structure with multiple stereocenters. Employed in glycosylation reactions to construct glycosidic bonds in carbohydrate mimetics. Applied in the development of enzyme inhibitors, particularly for glycosidases, leveraging its structural similarity to sugar transition states. Also utilized in the design of biologically active compounds where stereochemistry plays a critical role in activity.
