Used as a chiral building block in organic synthesis, particularly in the preparation of complex natural products and pharmaceuticals. Its protected alcohol and hydroxyl functionalities allow selective reactions in multi-step syntheses. Commonly employed in the development of antiviral and antitumor agents due to its ability to mimic sugar moieties and participate in stereoselective transformations. Also utilized in the synthesis of glycosidase inhibitors and other bioactive molecules where stereochemistry is critical.
