Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of antiviral and anticancer agents. Its structural features allow for easy functionalization, making it valuable in medicinal chemistry for building complex molecules. The presence of both hydroxyl and amine groups enables conjugation with other pharmacophores, enhancing drug solubility and bioavailability. Commonly employed in the preparation of protease inhibitors and kinase inhibitors due to its favorable stereochemistry and metabolic stability.
