产品介绍:

应用
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.

备注
Store away from oxidizing agents. Keep the container tightly closed and place it in a cool, dry and well ventilated condition.
