Used as a chiral catalyst in asymmetric synthesis, particularly in the reduction of prochiral ketones to produce enantiomerically enriched secondary alcohols. It is highly effective in borane-mediated reductions, offering high selectivity and yield. Commonly applied in pharmaceutical synthesis where precise stereochemistry is critical. Its structure allows for efficient control of the reaction’s stereochemical outcome, making it valuable in the preparation of chiral intermediates for drugs and fine chemicals.
