Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of protease inhibitors and other biologically active molecules. Its α,β-unsaturated carbonyl structure allows for Michael addition reactions, making it valuable in constructing complex organic frameworks. The Boc-protected amine group provides stability and selectivity during multi-step syntheses, especially in peptide-like structures. Commonly employed in medicinal chemistry for building blocks where controlled reactivity and functional group compatibility are essential.
