The Synthesis of New Chiral Dioxocyclens

Abstract

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.
