Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of bioactive molecules targeting central nervous system disorders. Its chiral pyrrolidine core makes it valuable in constructing stereoselective drug candidates, especially for protease inhibitors and receptor modulators. Commonly employed in medicinal chemistry for structure-activity relationship studies due to the stability and conformational rigidity it imparts to final compounds. Also utilized in the preparation of kinase inhibitors and antiviral agents. The tert-butyloxycarbonyl (Boc) protection allows for selective functionalization in multi-step syntheses.
