This compound is primarily used in pharmaceutical research and development as a key intermediate in the synthesis of complex organic molecules. Its spirocyclic structure makes it valuable for constructing rigid frameworks in drug design, particularly for targeting specific biological receptors. It is often employed in the preparation of potential therapeutic agents, such as enzyme inhibitors or receptor modulators, due to its ability to impart conformational stability to the molecules. Additionally, the tert-butoxycarbonyl (Boc) protecting group allows for selective deprotection during multi-step synthetic processes, enabling precise control over the chemical transformations. Its application is particularly relevant in the development of central nervous system (CNS) drugs, where spirocyclic compounds are known to exhibit favorable pharmacokinetic properties.
