Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of bioactive molecules targeting central nervous system disorders. 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 involving GABA analogs or enzyme inhibitors. Also utilized in the preparation of prodrugs due to the presence of the tert-butoxycarbonyl (Boc) protecting group, allowing for controlled reactivity during multi-step syntheses.
