Used as a chiral intermediate in the synthesis of biologically active compounds, particularly in the development of pharmaceuticals targeting protease enzymes. Its stereochemistry makes it valuable in constructing peptide-based drugs with high specificity. Commonly employed in the preparation of enzyme inhibitors, especially in the design of antiviral agents such as those for hepatitis C and other viral diseases. The protected functional groups allow for selective deprotection and coupling in multi-step organic syntheses, making it suitable for solid-phase peptide synthesis and medicinal chemistry research.
