Used as a key intermediate in pharmaceutical synthesis, particularly in the development of biologically active compounds. Its protected amine group and fluorinated pyrrolidine structure make it valuable for constructing drug candidates targeting central nervous system disorders and metabolic diseases. The Boc group allows for selective deprotection under mild conditions, enabling stepwise assembly of complex molecules. Commonly employed in medicinal chemistry for structure-activity relationship studies due to the metabolic stability imparted by the difluoromethylene group.
