Used as a chiral catalyst or chiral auxiliary in asymmetric synthesis, particularly in enantioselective phosphorylation reactions. Its binaphthyl backbone provides a rigid, sterically hindered environment that promotes high enantioselectivity. Commonly employed in the synthesis of chiral phosphates and phosphonates, which are key structural motifs in pharmaceuticals and biologically active compounds. Also utilized in catalytic systems for the asymmetric transformation of alcohols and diols, enabling the production of optically pure intermediates in fine chemical manufacturing.
