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.Related product price
