Typical Properties
Summary
(R)-(+)-1,1'-Bi-2-naphthol has many uses: as an assistant in asymmetric selective reduction of ketones; Ligands in chiral titanium catalysts are used for stereoselective reactions, such as glyoxylic acid reaction and Diels alder reaction; It is used as a chiral promoter in the asymmetric oxidation of sulfide to sulfoxide; Chiral lanthanide trifluoromethanesulfonic acid was synthesized from binaphthol and used as catalyst in asymmetric Diels alder reaction; Binaphthol derivatives have recently been found to be used in asymmetric cleisen rearrangement and asymmetric epoxidation; These lithium aluminum hydride derivatives of binap-h have been widely used in the reduction of ketones; Chiral binaphthol salt precursor, used for olefin epoxidation asymmetric reaction salt.
