Comparison of (R)-(-)-6,6'-Bis(3,5-dinitrobenzamido)biphenyl-2,2'-dicarboxylic and (S)-(+)-6,6'-Bis-(3,5-dinitrobenzamidomethyl)biphenyl-2,2'-dicarboxylic Acids as Chiral HPLC Selectors

Abstract

The title optically active diacids (R)-I and (S)-II of known absolute configuration were investigated as selectors in HPLC separation of enantiomers. With a standard set of benzamido alcohols and biaryl compounds, the separation was less efficient and less general than that found for selectors based on studied previously.
