Used as a key intermediate in the synthesis of biologically active compounds, particularly in pharmaceuticals. Its structure contains both a protected amine (Boc group) and an ester functionality, making it valuable in peptide synthesis and the construction of complex molecules. The cyclopropane ring introduces conformational rigidity, which is often exploited in drug design to enhance metabolic stability and receptor selectivity. Commonly employed in the development of protease inhibitors and other therapeutic agents where precise stereochemistry and steric constraints are important.
