Used as a chiral auxiliary in asymmetric synthesis, enabling the selective formation of stereoisomers in pharmaceutical and fine chemical manufacturing. Its rigid bicyclic structure helps control the stereochemical outcome of reactions such as alkylations, aldol additions, and Diels-Alder cyclizations. After serving its purpose, it can be cleaved under mild conditions, leaving the desired enantiomerically enriched product. Commonly employed in the synthesis of complex natural products and bioactive molecules where stereocontrol is critical.
