Used as a chiral auxiliary and resolving agent in organic synthesis, particularly in the preparation of enantiomerically pure compounds. Its rigid bicyclic structure and well-defined stereochemistry make it valuable in asymmetric synthesis and in the development of pharmaceutical intermediates. Commonly employed in the formation of sulfonamides to control stereochemistry during key reaction steps. Also utilized in catalysis and as a building block in the design of chiral ligands and organocatalysts.
