Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of central nervous system (CNS) agents. Its spirocyclic structure and protected amine functionality make it valuable in medicinal chemistry for constructing complex molecules with high selectivity and stability. Commonly employed in the preparation of kinase inhibitors and receptor modulators due to its favorable stereochemistry and ability to enhance bioavailability. Also utilized in research settings for scaffold diversification in drug discovery programs.
