Used as a highly enantioselective catalyst in asymmetric synthesis, particularly in cyclopropanation and C–H functionalization reactions. Its chiral environment enables high stereocontrol, making it valuable in the preparation of optically active pharmaceuticals and fine chemicals. Effective in catalyzing reactions with diazo compounds, it delivers excellent enantiomeric excess in the formation of chiral cyclopropanes—key structural motifs in drug development. The bulky dodecylphenylsulfonyl groups enhance solubility in organic solvents and contribute to catalyst stability and selectivity.
