Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of bioactive molecules targeting central nervous system disorders. Its spirocyclic structure and nitrogen heteroatom make it valuable in medicinal chemistry for constructing rigid scaffolds that enhance binding selectivity and metabolic stability. Commonly employed in the preparation of analogs for dopamine and serotonin receptor modulators. Also applied in research settings to explore new routes in heterocyclic compound synthesis.
