Used as a chiral ligand in asymmetric catalysis, particularly in enantioselective organic transformations. Its rigid cycloheptane backbone and stereogenic centers enable high stereocontrol in reactions such as alkylations, aldol additions, and cycloadditions. Commonly employed in coordination with metals like copper or nickel to form catalysts that promote the formation of chiral intermediates in pharmaceutical synthesis. Valued for its ability to induce high enantiomeric excess in target products.
