Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of central nervous system (CNS) agents and kinase inhibitors. Its spirocyclic structure and functional groups make it valuable for constructing complex molecules with high selectivity and potency. Commonly employed in medicinal chemistry for optimizing drug candidates due to its favorable physicochemical properties and ability to enhance metabolic stability. Also utilized in the preparation of bioactive compounds targeting neurological disorders and inflammatory conditions.
