This paper report. a very short and efficient synthesis of chiral dioxocyclens starting, from natural amino acids. NMR experiments undertaken to assess the chiral recognition properties of these chiral macrocycles. The NMR spectra of mandelic acid or its derivatives in the presence and absence of the chiral dioxocyclens showed that these macrocycles have different enantiomeric discriminating ability, It was revealed that this type of dioxocyclen may be promising hosts Cor chiral discrimination.
