Rediscovering Sodium Ionophores as Selective Agents for Lithium Recognition and Extraction

Angewandte Chemie, EarlyView.
Long‐classified sodium ionophores unexpectedly prefer lithium and act as efficient extractants in solid–liquid extraction (SLE). Readily prepared from catechol and haloacetamides, these hosts recover hydrated LiCl from multicomponent salt mixtures via a hydration‐assisted O···Li+ binding mode, enabling scalable lithium separation with Li/Na, Li/K, and ...

Antiaromaticity‐Driven Enhancement of Single‐Molecule Electrical Conductance by s‐Indacene Molecular Bridges

Angewandte Chemie, EarlyView.
Within the same molecular length scale, antiaromatic s‐indacene exhibits a marked increase in conductance compared to its aromatic benzodithiophene counterpart. Notably, the inherently small HOMO–LUMO gap of antiaromatic systems maintains a certain level of conductance even in the presence of cross‐conjugation.

Enantioselective Synthesis of Axially Chiral Diaryl Ethers via Rhodium‐Catalyzed [2 + 2 + 2] Cycloaddition

Angewandte Chemie, EarlyView.
An enantioselective rhodium‐catalyzed [2 + 2 + 2] cycloaddition enables the synthesis of axially chiral diaryl ethers. Carbonyl coordination ensures high reactivity and regioselectivity, affording products bearing up to four stereogenic axes with good enantio‐ and diastereoselectivity.

Carbohydrate Physicochemical Properties: The Innate Hydrogen Bond Donating Capacities of α‐Glucoside and α‐Galactoside Alcohol Groups

Angewandte Chemie, EarlyView.
Experimental determination of the innate hydrogen bond donating capacities of the glucose and galactose non‐anomeric alcohols revealed significant variations depending on position and relative configuration, which were quantified on the pKAHY scale, relevant for MedChem purposes, hence providing another tool toward rational glycomimetic development ...
