Used as a key intermediate in peptide synthesis and medicinal chemistry, particularly in the preparation of constrained amino acid derivatives. Its cyclopropane ring introduces structural rigidity, which helps stabilize specific peptide conformations for structure-activity relationship studies. The compound is also employed in the synthesis of protease inhibitors and other biologically active molecules where stereochemical control is important. The benzyloxycarbonyl (Cbz) group serves as a protecting group for the amine, allowing selective deprotection under mild conditions, making it compatible with multi-step synthetic routes. Commonly used in the development of pharmaceuticals targeting viral infections, cancer, and central nervous system disorders.
