Used primarily in organic synthesis, this compound serves as a key intermediate in the development of pharmaceuticals, particularly in the creation of complex molecules with spirocyclic structures. Its spirocyclic framework is valuable in drug design, offering unique spatial configurations that can enhance binding affinity and selectivity toward biological targets. The tert-butyl ester group provides stability and facilitates further chemical modifications, making it a versatile building block in medicinal chemistry. Additionally, it is employed in the synthesis of bioactive compounds, including potential treatments for neurological disorders, due to its ability to mimic certain natural structures in the brain.
