Used in pharmaceutical synthesis as a key intermediate for developing central nervous system (CNS) active compounds. Its structure supports the creation of selective receptor ligands, particularly for neurological targets such as serotonin and dopamine receptors. Commonly employed in the preparation of drug candidates for depression, anxiety, and addiction disorders due to its favorable stereochemistry and functional group compatibility. The tert-butyl protecting group allows for controlled deprotection during multi-step synthesis, enabling precise modification of the amine functionality. Its bicyclic scaffold enhances metabolic stability and blood-brain barrier penetration in final drug forms.
