Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of central nervous system (CNS) agents and analgesics. Its Boc-protected nitrogen group allows selective reactions in multi-step organic syntheses, while the free hydroxyl and allyl substituents at the 4-position provide opportunities for further functionalization. Commonly employed in medicinal chemistry for constructing piperidine-based drug candidates due to its structural stability and functional group compatibility. Also utilized in the preparation of protease inhibitors and receptor modulators where controlled polarity and steric hindrance are required.
