Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and other bioactive molecules. Its spirocyclic structure provides conformational rigidity, making it valuable in drug design for enhancing selectivity and metabolic stability. Commonly employed in medicinal chemistry for optimizing lead compounds in treatments targeting cancer, inflammation, and central nervous system disorders. Also utilized in the preparation of functionalized heterocycles for use in combinatorial chemistry and high-throughput screening.
