Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the production of antiviral and antitumor agents. Its hydroxyl and cyclic ether functional groups allow for selective chemical modifications, making it valuable in asymmetric synthesis. Commonly employed in the development of protease inhibitors and nucleoside analogs. Also utilized in the preparation of intermediates for drugs targeting central nervous system disorders. Its stereochemistry enables high enantioselectivity in reactions, improving the efficiency and purity of active pharmaceutical ingredients.
