(+)-BINOL Use and Manufacturing
Atropine isomeric diols have many uses: additives for asymmetric selective reduction of ketones; ligands in chiral titanium catalysts for stereoselective reactions, such as glyoxylic acid reaction, Diels-Alder reaction; Chiral auxiliary for catalyzing the asymmetric oxidation of sulfide to sulfoxide; chiral lanthanide trifluoromethanesulfonic acid from binaphthol, used as a catalyst in asymmetric Diels-Alder reaction; binaphthol Derivatives, recently discovered for asymmetric Claisen rearrangement reactions and asymmetric epoxidation reactions; the lithium aluminum hydride derivatives of these diols (BINAP-H) have been widely used in the reduction of ketones; chiral Precursor of binaphthol salt, a salt for asymmetric reaction of olefin epoxidation
