1,1′-Thiobis(2-naphthol)(CAT: M080022), also known as BINOL-S, is a chiral organic compound where two 2-naphthol units are linked by a sulfur atom at the 1-position of each naphthol. This compound is commonly used as a ligand in asymmetric catalysis, particularly in reactions requiring chiral induction, such as asymmetric hydrogenation and asymmetric addition reactions. The rigid and bulky structure of 1,1′-Thiobis(2-naphthol) allows it to create well-defined chiral environments around metal centers in catalytic complexes, making it highly valuable in enantioselective synthesis. Its applications are widely seen in pharmaceutical research, where producing enantiomerically pure compounds is crucial.
