Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of protease inhibitors and other bioactive molecules. Its enantiomerically pure structure makes it valuable for constructing complex organic compounds where stereochemistry is critical. The presence of both an alkene and a protected amine allows for selective functionalization through reactions such as olefin metathesis, hydrogenation, or cross-coupling, enabling efficient diversification in medicinal chemistry campaigns. Commonly employed in peptide mimetics and as an intermediate in the preparation of nitrogen-containing heterocycles.
