Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of peptide-based drugs and enzyme inhibitors. Its protected amine and carboxylic acid functional groups allow for selective coupling reactions, making it valuable in solid-phase and solution-phase peptide synthesis. The terminal alkene group enables further modification via reactions such as olefin metathesis or hydrofunctionalization, facilitating the introduction of structural diversity in drug discovery. Commonly employed in the preparation of intermediates for biologically active molecules, including antiviral and anticancer agents.
