## 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]
## Abstract magnified image One‐pot reaction of 3‐aryl‐5‐methyl‐1,3,4‐oxadiazolin‐2‐ones **1a‐g** with ethanolamine yielded the 4‐(2‐hydroxyethyl)‐2‐aryl‐5‐methyl‐2,4‐dihydro‐3__H__‐1,2,4‐triazolin‐3‐ones **2a‐g** which were converted to the azido compounds **6a‐g**. These azides on 1,3‐dipolar cy
