Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) requiring high enantiomeric purity. Its rigid bicyclic structure and functional groups make it valuable in asymmetric synthesis, especially for creating beta-amino acids and peptidomimetics. Commonly employed in the preparation of protease inhibitors and other bioactive molecules where stereochemistry plays a critical role in activity. Also utilized in medicinal chemistry for structure-activity relationship (SAR) studies due to its conformational constraints.
