Used as a key chiral building block in the synthesis of biologically active compounds, particularly in pharmaceutical development. Its strained cyclopropane ring and functional groups (hydroxyl and Boc-protected amine) allow for selective transformations, making it valuable in constructing peptidomimetics and protease inhibitors. Commonly employed in the preparation of antiviral and anticancer agents where stereochemistry and ring rigidity enhance target binding and metabolic stability. The Boc group enables easy protection-deprotection during multi-step syntheses, improving overall yield and purity.
