(S,S)-Taddol is a privileged chiral ligand for asymmetric catalysis, particularly in titanium- and aluminum-mediated reactions. It enables high enantioselectivity in nucleophilic additions to aldehydes and ketones. Researchers also employ it in enantioselective alkylations and cycloadditions. Its rigid structure enhances stereochemical outcomes in synthetic pathways.
