Used primarily in pharmaceutical research as a key intermediate in the synthesis of complex spirocyclic compounds. Its rigid spirocyclic framework and functionalized ring system make it valuable for developing bioactive molecules, particularly in central nervous system (CNS) drug discovery. The compound’s structure allows for selective interactions with neurological receptors, showing potential in the development of agents targeting cognitive disorders and neurodegenerative diseases. Additionally, its stability and stereochemistry support use in structure-activity relationship (SAR) studies to optimize drug candidates.
