R-Binol is 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

(R)-(+)-1,1'-bi-2-naphthol is obtained through resolution of racemic BINOL, which is usually made from 2-naphthol catalyzed by iron(III) chloride through radical reaction. (R)-(+)-1,1'-bi-2-naphthol has been widely used for various applications: 1) chiral inducing agents for catalytic, asymmetric reactions such as the Diels-Alder reaction,ene reaction,or as Lewisacids;2) enantioselective reduction of ketones;3) synthesis of chiral macrocyclesand otherinteresting compounds.
R-BINOL is white powder, could be dissolved in strong polar organic solvent, also named as (R)-(+)-(1,1'-binaphthalene)-2,2'-diol or (R)-(+)-1,1-binaphthol.
The supplying capacity is around 1000Kgs per month and its chemical purity is reached over 99%, and optical purity over 99.5%ee, which could be delivered by air or by sea upon the ordered quantity and your requirement.
