Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) that require functionalized piperidine scaffolds. The tert-butoxycarbonyl (Boc) group serves as a temporary protecting group for the piperidine nitrogen, while its epoxide group allows for ring-opening reactions, enabling the introduction of various substituents for structural diversification. Commonly employed in medicinal chemistry for constructing complex molecules with biological activity, including CNS-targeted drugs such as antidepressants and anxiolytics, and receptor modulators. Also utilized in research settings for generating compound libraries in drug discovery programs.
