Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of bioactive molecules with central nervous system activity. Its azetidine core provides structural rigidity, enhancing metabolic stability in drug candidates. Commonly employed in medicinal chemistry for constructing small-molecule inhibitors and receptor modulators. Also utilized in the preparation of protease inhibitors and compounds targeting neurological disorders. The tert-butoxycarbonyl (Boc) group allows for easy protection of the nitrogen, enabling selective reactions in multi-step organic syntheses.
