Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of central nervous system agents and cognitive enhancers. Its spirocyclic structure contributes to conformational rigidity, making it valuable in medicinal chemistry for designing bioactive molecules with improved selectivity and metabolic stability. Commonly employed in research settings to construct novel heterocyclic compounds with potential nootropic or neuroprotective activity. Also utilized in the preparation of chiral building blocks for asymmetric synthesis.
