Widely used as a chiral catalyst in asymmetric synthesis, particularly in enantioselective transformations such as allylic alkylation and related carbon–carbon bond-forming reactions. Its rigid, sterically hindered structure enables high stereocontrol, making it valuable in the preparation of optically active pharmaceutical intermediates and fine chemicals. Commonly employed in transition metal-catalyzed reactions where precise chirality transfer is required. Also utilized in research settings for developing new asymmetric methodologies due to its stability under various reaction conditions and ability to induce high enantiomeric excess.
