Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and other bioactive molecules. Its spirocyclic structure provides structural rigidity, which is beneficial for enhancing selectivity and metabolic stability in drug candidates. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies due to the presence of modifiable functional groups. Also utilized in the preparation of analogs for central nervous system (CNS)-targeted therapeutics owing to its favorable physicochemical properties and potential blood-brain barrier permeability.
