Description

Atropine isomeric diols have many uses: auxiliary agents in asymmetric selective reduction of ketones; ligands in chiral titanium catalysts for stereoselective reactions, such as glyoxylic acid reactions, Diels-Alder reactions; A chiral auxiliary used to catalyze the asymmetric oxidation of sulfide to sulfoxide; chiral lanthanide trifluoromethanesulfonic acid is generated from binaphthol, which is used as a catalyst for asymmetric Diels-Alder reaction; Binaphthol derivatives, recently discovered for use in asymmetric Claisen rearrangements and asymmetric epoxidations; lithium aluminum hydride derivatives of these diols (BINAP-H), have been widely used in the reduction of ketones ; Chiral binaphthol salt precursor, salt for asymmetric reaction of olefin epoxidation.
