Used as a highly efficient chiral catalyst in asymmetric synthesis, particularly in enantioselective cyclopropanation reactions. It enables the formation of chiral cyclopropane rings with high enantiomeric excess, which are key structural motifs in pharmaceuticals and biologically active compounds. Its robust performance in catalyzing reactions between diazo compounds and alkenes makes it valuable in the development of complex organic molecules, especially in drug discovery and fine chemical manufacturing. The presence of bulky chiral ligands enhances stereocontrol, offering excellent selectivity in transformations where precise spatial arrangement is critical.
