Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of neuroprotective agents and treatments for neurological disorders. Its spirocyclic structure and functional groups make it valuable in medicinal chemistry for designing molecules that can cross the blood-brain barrier. Commonly employed in research settings to build potent glutamate receptor modulators, especially targeting NMDA and AMPA receptors involved in synaptic transmission and neurodegeneration. Also utilized in the preparation of enzyme inhibitors and cognitive enhancers in preclinical drug discovery programs.
