Used as a key intermediate in organic synthesis, particularly in the development of pharmaceuticals. It is often employed in the preparation of spirocyclic compounds, which are valuable in drug discovery due to their unique structural properties. The compound’s spirocyclic framework makes it useful for creating molecules with potential biological activity, such as enzyme inhibitors or receptor modulators. Additionally, it is utilized in peptide chemistry, where the benzyloxycarbonyl (Cbz) group serves as a protecting group for amines during complex synthetic processes. Its application extends to the synthesis of heterocyclic compounds, which are important in medicinal chemistry for designing new therapeutic agents.
