Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of bioactive molecules with potential neurological or metabolic activity. Its spirocyclic structure and functional groups make it valuable for constructing complex heterocycles in medicinal chemistry. Commonly employed in research settings to build novel drug candidates, especially those targeting central nervous system disorders or enzyme modulation. The tert-butoxycarbonyl (Boc) protecting group allows for selective reactions in multi-step organic syntheses, enhancing its utility in peptide-like frameworks and heterocyclic derivatization.
