Description

It is used in biosynthetic preparation for enantioselective oxidation of naphthols to binaphthyldiols with horseradish peroxidase catalyst. 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.5 The lithium aluminum hydride derivative of these diols (BINAP-H) has been used extensively for the reduction of ketones. Chiral binapthol imminium salt precursor. Salts were used for an asymmetric epoxidation of olefins. This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
