Used in pharmaceutical research as a key intermediate in the synthesis of bioactive molecules, particularly in developing compounds with central nervous system activity. Its spirocyclic structure contributes to conformational rigidity, making it valuable in medicinal chemistry for enhancing selectivity and metabolic stability. Commonly employed in the design of receptor modulators, especially for neurological targets such as serotonin and dopamine receptors. Also utilized in the development of peptidomimetics due to its ability to mimic peptide bond geometry while improving bioavailability.
