## Abstract Chiral discrimination studies using (+)‐(18‐crown‐6)‐2,3,11,12‐tetracarboxylic acid (18‐C‐6‐TA) as a chiral selector were performed by high‐performance liquid chromatography (HPLC) and NMR spectroscopy. The enantiomers of alanine (Ala) or alanine methyl ester (Ala‐ME) were well separate
