Used in pharmaceutical synthesis as a chiral building block for developing bioactive molecules, particularly in the production of protease inhibitors and antiviral agents. Its rigid cyclopentane backbone and defined stereochemistry make it valuable for enhancing selectivity and metabolic stability in drug candidates. Commonly employed in the development of enzyme inhibitors where stereochemistry plays a critical role in activity. Also utilized in the preparation of peptidomimetics due to its structural similarity to natural amino acids.
