Used in pharmaceutical synthesis as a chiral building block for the preparation of biologically active compounds. Its cyclopropane core with defined stereochemistry makes it valuable in the development of drug candidates targeting central nervous system disorders and inflammatory conditions. The tert-butyl carbamate (Boc) group allows for easy protection and deprotection of the amine during multi-step synthesis, enhancing its utility in medicinal chemistry. Commonly employed in the design of protease inhibitors and receptor modulators due to its structural rigidity and favorable metabolic stability.
