Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of central nervous system (CNS) agents. Its structure supports the creation of bioactive molecules by serving as a protected amine building block with a constrained cyclobutane ring, which can enhance metabolic stability and binding selectivity. Commonly employed in medicinal chemistry for optimizing drug candidates targeting neurological disorders. Also utilized in the preparation of protease inhibitors and receptor modulators due to its favorable stereochemistry and functional group compatibility.
