This compound is primarily utilized in organic synthesis as a versatile building block, particularly in the development of complex molecules. Its spirocyclic structure makes it valuable for constructing constrained frameworks, which are often required in medicinal chemistry for drug discovery. The tert-butyl ester group provides stability and can be selectively removed under mild conditions, allowing for further functionalization. Additionally, the presence of nitrogen and oxygen atoms in the ring system enables its use in the synthesis of heterocycles, which are common motifs in pharmaceuticals and agrochemicals. Its application extends to the preparation of peptidomimetics and other biologically active compounds, where its rigid structure can mimic natural peptides and enhance binding affinity.
