Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of protease inhibitors and other bioactive molecules. Its chiral structure makes it valuable in asymmetric synthesis, enabling the production of enantiomerically pure drugs. Commonly employed in medicinal chemistry research to create potential treatments for diseases such as HIV and hepatitis C. Also utilized in the preparation of peptidomimetics, which mimic peptides to modulate biological processes. Its stability and reactivity make it suitable for complex organic transformations in drug discovery pipelines.
