Two amphiphilic chiral receptors 2a and 2b were designed and synthesized. Both are efficient chiral solvating agents for chiral carboxylic acids. In particular, 2a is an excellent CSA not only for lipophilic guests, but also for some hydrophilic guests. It is the first CSA for the direct determination of the enantiomeric composition of hydrophilicchiral hydroxylated acid in protic polar solvent.
