Used as a chiral auxiliary in asymmetric synthesis, particularly in the preparation of enantiomerically pure compounds. It is effective in controlling stereochemistry during reactions like aldol additions, Diels-Alder reactions, and alkylations. Its rigid structure and ability to induce high enantioselectivity make it valuable in pharmaceutical and fine chemical industries for producing chiral intermediates. Additionally, it is employed in the synthesis of complex natural products and bioactive molecules, enhancing the efficiency and selectivity of synthetic routes.
