Chiral zwitterion ion exchangers represent efficient chiral stationary phases for stereoselective resolution of various analytes including chiral acids, bases, and zwitterions. In this contribution, we have focused on utilization of chiral zwitterionic sorbents, denoted as ZWIX (+A) and ZWIX (−A). These are analogical chiral systems to commercially available columns, Chiralpak ZWIX (+) and Chiralpak...
In continuation of our efforts to synthesize a highly dedicated strong cation exchanger, we introduce four chiral stationary phases based on a laterally substituted naphthalene core featuring chiral 2‐aminocyclohexansulfonic acid as the chiral cation‐exchange site. The selectors were modified with two different terminal units, which enabled immobilization to the silica support by thiol–ene radical...
