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.
