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. 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.
