Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of enzyme inhibitors and receptor modulators. Its rigid bicyclic structure and defined stereochemistry make it valuable for designing drugs with high selectivity and potency, especially in central nervous system agents and antiviral compounds. Commonly employed in asymmetric synthesis to introduce stereochemical control, it enhances the metabolic stability and bioavailability of active pharmaceutical ingredients. Also utilized in the preparation of peptidomimetics due to its ability to mimic peptide conformations while resisting degradation.
