Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of biologically active molecules targeting central nervous system disorders. Its structure allows for selective functionalization, making it valuable in medicinal chemistry for building complex heterocyclic systems. Commonly employed in research settings to construct beta-amino acid derivatives and enzyme inhibitors. Also utilized in the preparation of peptidomimetics due to its rigid azetidine core, which can enhance metabolic stability and bioavailability in drug candidates.
