Used as a chiral building block in the synthesis of pharmaceuticals and biologically active compounds. Its rigid cyclopropane ring and defined stereochemistry make it valuable for developing enantioselective drugs, particularly in the design of enzyme inhibitors and receptor modulators. The tert-butyl ester group enhances lipophilicity and stability during synthetic transformations, allowing for selective protection and deprotection strategies in multi-step organic syntheses. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies due to its conformational constraint and ability to influence molecular geometry.
