Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of bioactive molecules that target central nervous system disorders. Its spirocyclic structure and functional groups make it valuable for constructing complex heterocycles in medicinal chemistry. Commonly employed in coupling reactions to introduce the 2-azaspiro[3.3]heptane scaffold, which can enhance metabolic stability and improve pharmacokinetic properties in drug candidates. Also utilized in research settings for the preparation of novel receptor modulators and enzyme inhibitors.
