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 defined stereochemistry make it valuable in designing drugs targeting central nervous system disorders, including antidepressants and antipsychotics. The tert-butyl carbamate (Boc) group facilitates protection of the amine during multi-step syntheses, allowing selective reactions at other functional sites. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies due to its ability to influence bioavailability and receptor selectivity.
