Used as a key intermediate in the synthesis of biologically active compounds, particularly in pharmaceutical research. It serves as a protected amine derivative in the development of cyclopropane-containing molecules, which are often found in drugs targeting the central nervous system. Its structural rigidity helps in conformational restriction of peptides and small molecules, enhancing selectivity and metabolic stability. Commonly employed in medicinal chemistry for building blocks in the design of protease inhibitors and receptor modulators.
