Abstract
The enantiomeric atropoisomers of 1,1'-binaphthyl-2,2'-diol (BINOL) have become one of the most widely used chiral ligands and auxiliaries for asymmetric synthesis. This review provides an overview of enantioselective synthesis of optical active BINOLs by straightforward asymmetric oxidative coupling of identical 2-naphthol and its substituted derivatives.
