Used as a chiral intermediate in the synthesis of biologically active compounds, particularly in the development of enantiomerically pure pharmaceuticals. Its rigid imidazolidine backbone and stereodefined centers make it valuable in asymmetric synthesis, where it can serve as a building block for protease inhibitors or receptor modulators. The tert-butyl carbamate (Boc) group allows for easy protection and deprotection during peptide-like chain elongation. Commonly employed in medicinal chemistry for optimizing stereochemistry in drug candidates targeting central nervous system disorders and inflammatory diseases.
