Used as a key chiral intermediate in the synthesis of pharmaceutical agents, particularly in the development of antiviral and antidiabetic drugs. Its stereochemistry enables high selectivity in biological targeting, improving drug efficacy and reducing side effects. Commonly employed in the production of protease inhibitors due to its ability to mimic peptide structures and resist metabolic degradation. Also utilized in the preparation of kinase inhibitors for oncology applications. Its tert-butyl carbamate (Boc) protection allows for controlled deprotection during multi-step syntheses, making it valuable in complex molecule assembly.
