Structural Formula:

Molecular Formula: C20H14O2 Molecular Weight: 286.32 Linear Formula: HOC10H6C10H6OH CAS Number: 18531-94-7 Beilstein Registry Number: 3616837 MDL number: MFCD00004068 PubChem Substance ID: 24854837
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.
