Chiral recognition of binaphthyls by permethylated β-cyclodextrin

Abstract

The (S)-enantiomers of binaphthyl derivatives such as 1,1′-bi-2-naphthol, 2,2′-dimethoxy-1,1′-binaphthyl, and 1,1′-binapthyl-2,2′-diyl hydrogen phosphate are more preferable guests for permethylated β-cyclodextrin compared with the (R)-enantiomers.
