Preparación de un plausible eje de rotaxano quiral aminoácido-esteroide

Abstract

Rotaxanes are compounds that are made up of two submolecular components: a cyclic one (a ring) and a linear one (an axis) that threads the previous one and that, in addition, has bulky groups at their ends in order to keep both components intertwined. Another simple tool to keep this type of macrostructures anchored is through non-covalent bonds such as hydrogen bonds, coordination bonds with metal ions and aromatic π-π interactions, among others. In this work the rapid and quantitative synthesis of a conductive thread (chiral axis) composed of chiral molecules is reported, which give it excellent anchoring properties important for the synthesis of rotaxanes.
