Application

(S)-(-)-5,5′,6,6′,7,7′,8,8′-Octahydro-1,1′-bi-2-naphthol is a key chiral auxiliary in asymmetric catalysis, particularly for C-C bond-forming reactions like the Suzuki-Miyaura coupling. It serves as a precursor for BINOL-derived phosphoric acid catalysts used in enantioselective transformations. Researchers also employ it as a ligand for titanium- and zirconium-based systems in stereoselective oxidations and reductions.
