  N-Carboxymethyl(Cm-)amino acids and their mono- and diesters were prepared by several routes, and their physical and chiroptical properties were compared with those of the parent amino acids and their esters. The isolation procedure was improved for the preparation of the free Cm-amino acids obtained from the corresponding amino acids and bromoacetic acid; the aimed-at compounds were also obtained

  This article reports a short and efficient synthesis of chiral dioxocyclens starting from natural amino acids. Four new chiral dioxocyclens that contain different substituents at the chiral center were obtained. These dioxocyclens could not only be used for chiral recognition, but provide a feasible way for the synthesis of chiral cyclens.
