Used as a chiral building block in the synthesis of peptide-based pharmaceuticals, particularly in the development of enzyme inhibitors and bioactive molecules. Its terminal alkene group allows for further functionalization via cross-coupling reactions or olefin transformations, enabling structural diversification. The Boc-protected amine ensures compatibility with standard peptide coupling protocols, making it valuable in solid-phase and solution-phase peptide synthesis. Commonly employed in medicinal chemistry for constructing non-natural amino acid residues in drug candidates.
