Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of bioactive molecules targeting central nervous system disorders. Its structure allows for selective modifications, making it valuable in medicinal chemistry for creating analogs with improved potency and metabolic stability. Commonly employed in the preparation of kinase inhibitors and receptor modulators due to the constrained azetidine ring and the presence of a protected amine group, which facilitates peptide coupling and other functional group transformations. Also utilized in the design of drug candidates requiring enhanced blood-brain barrier penetration.
