## Abstract Three novel chiral packing materials for high‐performance liquid chromatography were prepared by covalently binding of (2S)‐N‐(3,5‐dimethylphenyl)‐2‐[(4‐chloro‐3,5‐dinitrophenyl)carbonylamino]propan‐amide (**7**), (2S)‐N‐(3,5‐dimethylphenyl)‐2‐[(4‐chloro‐3,5‐dinitrophenyl)carbonylamino]
