Used as an intermediate in the synthesis of biologically active compounds, particularly in pharmaceutical research. Its cyclopropane core with a substituted aryl group makes it valuable for constructing constrained peptidomimetics and enzyme inhibitors. The tert-butyl carbamate (Boc) group serves as a protecting group for amines, enabling controlled deprotection during multi-step syntheses. Commonly employed in the development of central nervous system agents and anti-inflammatory drugs due to its ability to enhance metabolic stability and influence stereochemistry in final molecules.
