摘要：

From tentative beginnings, chiral ionic liquids have emerged into functionalized and tailor-made materials that provide novel input in classical asymmetric synthesis and separations. However, despite this broad application range the prediction of any chiral ionic liquids’ performance is difficult. We present a systematic study toward the chiral recognition properties of novel ionic liquids with an amino alcohol sub-structure derived from the chiral pool precursors ephedrine, prolinol, and phenylalaninol. The influence of different ionic head groups and core structures on the diastereomeric interactions between racemic Mosher’s acid carboxylate and enantiopure chiral ionic liquids was systematically investigated to provide insight into their recognition properties prior to application of these chiral ionic liquids in various fields.
