Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of enzyme inhibitors and receptor antagonists. Its structure supports the construction of bioactive molecules with improved metabolic stability and binding affinity. Commonly employed in medicinal chemistry for optimizing drug candidates targeting central nervous system disorders and inflammatory diseases. The Boc-protected azetidine scaffold allows for selective functionalization, making it valuable in solid-phase and solution-phase peptide-like synthesis. Also utilized in the preparation of fluorinated analogs to enhance pharmacokinetic properties such as membrane permeability and resistance to oxidative degradation.
