Used as a key chiral intermediate in the synthesis of pharmaceutical agents, particularly in the production of protease inhibitors. Its stereochemistry enables selective reactions critical for creating biologically active molecules. Commonly employed in the development of antiviral drugs, especially those targeting HIV and hepatitis C. The compound’s functional groups allow for efficient coupling and modification in multi-step synthetic routes, making it valuable in medicinal chemistry for building complex drug structures with high enantiomeric purity.
