Used as a key chiral intermediate in the synthesis of pharmaceutical agents, particularly in the development of antiviral and antidiabetic drugs. Its stereochemistry allows for selective reactions in multi-step organic syntheses, making it valuable in constructing complex molecules with high enantiomeric purity. Commonly employed in the preparation of protease inhibitors and kinase inhibitors due to the functional groups that enable further derivatization. Widely utilized in medicinal chemistry for structure-activity relationship (SAR) studies.
