Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of central nervous system (CNS) agents. Its spirocyclic structure contributes to conformational rigidity, making it valuable in designing bioactive molecules with improved selectivity and metabolic stability. Commonly employed in the preparation of cognition-enhancing drugs and treatments for neurological disorders due to its ability to cross the blood-brain barrier. Also utilized in medicinal chemistry research for structure-activity relationship (SAR) studies involving heterocyclic compounds.
