Used in pharmaceutical synthesis as a key intermediate for developing bioactive molecules, particularly in the preparation of kinase inhibitors and central nervous system agents. Its spirocyclic structure and protected functional groups make it valuable for constructing complex heterocycles in drug discovery. Commonly employed in medicinal chemistry for scaffold diversification due to its stability and selective reactivity. Also utilized in the development of protease inhibitors and receptor modulators where structural rigidity enhances binding affinity and metabolic stability.
