Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of active ingredients for central nervous system (CNS) drugs. Its rigid bicyclic structure and chiral centers make it valuable for designing selective receptor ligands, especially in antidepressants and antipsychotics. The tert-butyl carbamate (Boc) group allows for easy protection of the secondary amine during peptide coupling or multi-step synthesis, enabling controlled functionalization. Commonly employed in medicinal chemistry for building blocks in drug discovery due to its stability and stereochemical integrity.
