Abstract:
(R)-l,l'-binaphthalene-2,2'-diol-mono-[(-)-menthyl] carbonate (1) and (S)-l,l'-binaphthalene-2,2'-diol-mono-[(-)-menthyl] carbonate (2) are two new compounds synthesized from racemic binaphthol by diastereoselective crystalization after derivatization with (-)-menthyl chloroformate. Reduction of these monoesters would afford pure enantiomers of binaphthol, which are important C2-symmetrical compouds for asymmetric catalysis and the starting material for many other important chiral binaphthyl compounds.
