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.^2, 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.
