Narcissistic chiral self-sorting of molecular face-rotating polyhedra

Narcissistic chiral self-sorting prevailed in the assembly of molecular face-rotating polyhedra from a C3h building block 5,5,10,10,15,15-hexabutyl-truxene-2,7,12-tricarbaldehyde and racemic mixtures of 1,2-diamines.

Taking advantage of Co(II) induced enhanced VCD for the fast and sensitive determination of enantiomeric excess

Large Co(II)-induced VCD signals provide a method for determining the enantiomeric excess of α-amino acids. This strategy can be followed for building new VCD protocols.

Disulphide bond exchange inhibited by air – kinetic and thermodynamic products in a library of macrocyclic cysteine derivatives

Oxidation of dithiols provides strained monomeric macrocycles which transform upon disulphide bond exchange into stable dimers.

Supramolecular chiroptical switching of helical-sense preferences through the two-way intramolecular transmission of a single chiral source

Complexation-induced reversal of helical-sense preferences is demonstrated with a simple molecule with a pair of exciton-coupled chromophores.

Neutral glycoconjugated amide-based calix[4]arenes: complexation of alkali metal cations in water

Novel water-soluble calix[4]arene glycoconjugates with efficient cation-binding sites were synthesized and their complexation reactions in methanol and aqueous solutions were studied.

Unexpected cleavage of upper rim-bridged calix[4]arenes leading to linear oligophenolic derivatives

Upper rim-bridged calix[4]arenes possess an unprecedented reactivity as a consequence of their high internal strain imposed by the single bond bridge.

Complete tetraglycosylation of a calix[4]arene by a chemo-enzymatic approach

It was demonstrated that a calixarene can be a substrate for glycosyltransferases and thanks to an exhaustive glycosylation a multivalent tetralactosaminyl calix[4]arene was obtained.

A modular approach towards functionalized highly stable self-complementary quadruple hydrogen bonded systems

This article reports a new class of highly reactive dithiane-tethered self-complementary quadruple hydrogen-bonded systems without having prototropy-related issues. These systems further reacted with different amines to form highly stable molecular duplexes.

Conformational isomerism in cyclic peptoids and its specification

Conformational chirality is an emerging and neglected property of rigid cyclic peptoids determining structural, catalytic, and biological properties. The present contribution analyzes its impact and sets the configurational rules to define it.
