Used as a key intermediate in the synthesis of pharmaceutical agents, particularly in the development of protease inhibitors and other biologically active molecules. Its rigid bicyclic structure and functional groups make it valuable for constructing stereochemically defined compounds, especially in medicinal chemistry for optimizing drug potency and metabolic stability. Commonly employed in the preparation of enzyme inhibitors where precise spatial orientation of functional moieties is critical. Also utilized in research settings for scaffold development in peptidomimetic design.
