Used as a chiral auxiliary in asymmetric synthesis, enabling the selective formation of stereoisomers in complex organic reactions. Its rigid bicyclic structure helps control the spatial orientation of reactants, improving enantioselectivity in alkylations, aldol reactions, and Diels-Alder cycloadditions. Commonly employed in pharmaceutical synthesis where precise stereochemistry is critical. After serving its role, it can be cleaved under mild conditions, leaving the desired chiral product intact. Also utilized in the development of enantiomerically pure agrochemicals and fragrances.
