Used as a chiral building block in the synthesis of biologically active compounds, particularly in the development of peptidomimetics and pharmaceutical intermediates. Its protected amino group and carboxylic acid functionality allow for selective coupling reactions in multi-step organic syntheses. The presence of a terminal alkene enables further modification via cross-metathesis or hydrofunctionalization reactions. Commonly employed in the preparation of enzyme inhibitors and structurally constrained amino acid derivatives for drug discovery research.
