(S)-(-)-联萘酚 Product No.: SRCHEM0001 Description: (S)-(-)-1,1'-Bi-2-naphthol Synonyms: (S)-(-)-联萘酚 (S)-(-)-联二萘酚 (S)-(-)-1,1'-联-2-萘酚 (S)-(-)-2,2'-羟基--1,1'-联萘 (S)-(-)-1,1'-Bi(2-naphthol) (S)-(-)-1,1'-Binaphthalene-2,2'-diol (S)-(-)-2,2'-Dihydroxy-1,1'-dinaphthyl (S)-(-)-BINOL Structural Formula:

Molecular Formula: C20H14O2 Linear Formula: HOC10H6C10H6OH Molecular Weight: 286.32 CAS Number: 18531-99-2 Beilstein Registry Number: 4296068 MDL number: MFCD00004068 PubChem Substance ID: 24854838
Application: A chiral auxiliary used in the catalytic asymmetric oxidation of sulfides to sulfoxides. Chiral lanthanide triflates formed from binaphthol serve as catalysts for asymmetric Diels-Alder reactions. Derivatives of binaphthol have recently found use in asymmetric Claisen rearrangements and asymmetric epoxidations. The lithium aluminum hydride derivative of these diols (BINAP-H) has been used extensively for the reduction of ketones.
