Used as a specialty intermediate in organic synthesis, particularly in the development of pharmaceuticals and bioactive compounds. Its rigid spirocyclic structure makes it valuable for constructing complex molecular frameworks with defined stereochemistry. It is often employed in the design of enzyme inhibitors and receptor ligands due to its ability to mimic peptide-like conformations. Additionally, derivatives of this compound have shown potential in medicinal chemistry for central nervous system agents and antimicrobial research. Its unique heteroatom arrangement also supports use in catalysis and as a building block in materials science for novel heterocyclic polymers.
