Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of bioactive molecules and drug candidates. Its spirocyclic structure and functional groups make it valuable for constructing complex heterocyclic systems found in medicinal chemistry. Commonly employed in the preparation of kinase inhibitors and central nervous system agents due to its ability to mimic peptide-like structures and enhance metabolic stability. Also utilized in research settings for scaffold diversification in combinatorial chemistry and library synthesis.
