Used as a key intermediate in the synthesis of pharmaceutical agents, particularly in the development of neuroactive compounds and central nervous system modulators. Its spirocyclic structure and chiral center make it valuable for constructing stereoselective drug candidates, especially in treatments targeting neurological disorders such as epilepsy, depression, and neuropathic pain. The tert-butyl carbamate group serves as a protected amine, enabling controlled functionalization in multi-step organic syntheses. It is also employed in medicinal chemistry for optimizing pharmacokinetic properties like metabolic stability and blood-brain barrier penetration.
