Chemistry – A European Journal, EarlyView.This paper reports on creating a novel synthetic route of kanamycins A and B using the desymmetric boron‐mediated aglycon delivery (BMAD) reaction of meso‐diol acceptor with 1,2‐anhydro donor and regio‐ and stereoselective glycosylation of diol acceptor with trichloroacetimidate donor for introduction of a set of challenging 1,2‐cis‐glycosidic linkages

S‐Containing Double Helicenes Featuring Robust Radical Cations
Chemistry – A European Journal, EarlyView.This study introduces two S‐containing double helicenes with robust radical cations. X‐ray crystallography shows twisted conformations matching DFT‐calculated minima. Chemical oxidation of these double helicenes produced π‐conjugated radical cations, which remained stable in solution for weeks.

Chemistry – A European Journal, EarlyView.A novel family of water‐soluble, nontoxic, and phosphorescent N‐glycosylated Ru(II) phenanthroline‐based complexes are reported. They exhibit photoselectivity indexes ranging from 10 to 44 in PC‐3 cells, while impacting cell migration and resistance to detachment after irradiation with blue light.

Chemistry – A European Journal, EarlyView.(‐)‐Menthide and trans (+)‐carvomenthide, differing only in substitution pattern, were polymerized via ROP using a bis(phenolate) yttrium catalyst. Kinetic studies showed faster polymerization of (+)‐carvomenthide but greater control with (‐)‐menthide. Experimental and DFT analyses revealed mechanistic differences in chain propagation, highlighting how

Chemistry – A European Journal, EarlyView.The stereochemical diversity of the “glycan code” enables similar chiral motifs to arise from both D‐ and L‐sugars. Focused on DC‐SIGN–glycan recognition, two diverse monosaccharide scaffolds, D‐Man (D‐Rha) and L‐Gal (L‐Fuc), maintain the exquisite stereochemistry encoded in the minimal binding epitope.

The Ascent of Supramolecular Polymers and Gels in Asymmetric Catalysis
Chemistry – A European Journal, Accepted Article.Supramolecular polymers and gels, formed by the spontaneous assemblies of small molecules through various types of non‐covalent interactions, are attractive materials for many applications. Their modularity also offers many opportunities in asymmetric catalysis, that have been tackled in the last two decades and more intensively in the last one.
