Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of bioactive molecules that target central nervous system disorders. Its spirocyclic structure and iodine functionality make it valuable for coupling reactions in medicinal chemistry, especially in Suzuki and Negishi cross-coupling reactions to build complex molecular architectures. The tert-butyl carbamate (Boc) group provides amine protection during multi-step syntheses, allowing selective reactivity. It is also employed in the preparation of novel receptor ligands and enzyme inhibitors where structural rigidity enhances binding affinity and metabolic stability.
