We recently reported a new C3‐symmetric (R)‐phenylglycinol N‐1,3,5‐benzenetricarboxylic acid‐derived chiral high‐performance liquid chromatography (HPLC) stationary phase (CSP 1) that demonstrated better results as compared to a previously described N‐3,5‐dintrobenzoyl (DNB) (R)‐phenylglycinol‐derived CSP. Over a decade ago, (S)‐leucinol, (R)‐phenylglycine, and (S)‐leucine derivatives were used as
我们最近报道了一种新的C3对称(R)-苯基甘氨醇N -1,3,5-苯三甲酸衍生的手性高效液相色谱(HPLC)固定相(CSP 1),与先前描述的结果相比具有更好的结果N -3,5-二硝基苯甲酰(DNB)(R)-苯基甘氨醇衍生的CSP。十多年前,(S)-亮氨酸,(R)-苯甘氨酸和(S)-亮氨酸衍生物被用作基于3,5-DNB的Pirkle型CSP的手性分离原料。在这项研究中,通过结合上述想法和结果,准备了三个新的C3对称CSP(CSP 2、3和4)。在这里,我们描述了新的C3对称CSP(CSP 2–CSP 4)的合成程序和应用。
