Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. Its spirocyclic structure and boronic acid functionality make it valuable in Suzuki-Miyaura cross-coupling reactions, enabling the formation of complex biaryl systems found in bioactive molecules. Commonly employed in medicinal chemistry for constructing drug candidates targeting inflammatory diseases and oncology. The Boc-protected amine allows for selective deprotection and further functionalization, enhancing its utility in multi-step synthetic routes.
