Used primarily as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of central nervous system (CNS) agents. Its spirocyclic structure and nitrogen functionality make it valuable in medicinal chemistry for designing bioactive molecules with improved selectivity and metabolic stability. It is also employed in the preparation of kinase inhibitors and receptor modulators, where the rigid scaffold helps enhance binding affinity. Additionally, it finds use in research settings for building novel heterocyclic compounds during drug discovery programs.
