reversed-phase HPLC on popular chiral stationary phases. The best separation parameters were achieved on the chiral phases with the polysaccharide base Chiralcel OD-H and Chiralpack AD under the normal-phase HPLC conditions. The (S)- and (R)-enantiomers of 2-(1-naphthyloxy)- and 2-(2-iodophenoxy)propionic acids with enantiomeric excess ee >99% were isolated using preparative chiral HPLC.
通过正相和反相 HPLC 在流行的手性固定相上研究了分离许多具有实际意义的 2-芳氧基羧酸的对映异构体的可能性。在正相 HPLC 条件下,使用多糖基 Chiralcel OD-H 和 Chiralpack AD 的手性相实现了最佳分离参数。使用制备型手性 HPLC 分离对映体过量 ee > 99% 的 2-(1-萘氧基)-和 2-(2-碘苯氧基)丙酸的 (S)-和 (R)-对映体。
