Used as an intermediate in the synthesis of biologically active compounds, particularly in pharmaceutical research. Its spirocyclic structure with fluorinated substituents enhances metabolic stability and membrane permeability, making it valuable in the development of drug candidates targeting central nervous system disorders and inflammatory diseases. The tert-butyl carbamate (Boc) group serves as a protecting group for amines, enabling controlled stepwise synthesis in complex molecule assembly. It is also employed in medicinal chemistry for structure-activity relationship (SAR) studies due to its conformational rigidity and lipophilicity.
