Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of central nervous system (CNS) agents. 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 targeting neurological disorders due to its favorable stereochemistry and ability to enhance metabolic stability. Also utilized in the preparation of kinase inhibitors and receptor modulators where rigid scaffolds improve binding affinity.
