Used in pharmaceutical research as a key intermediate in the synthesis of biologically active compounds, particularly in the development of central nervous system agents. Its spirocyclic structure provides conformational rigidity, making it valuable in drug design for enhancing selectivity and metabolic stability. Commonly employed in the preparation of receptor modulators, including those targeting neurological disorders such as depression, anxiety, and schizophrenia. Also utilized in the optimization of kinase inhibitors and other therapeutic small molecules due to its favorable physicochemical properties and ability to improve blood-brain barrier penetration.
