Tailoring Structure–Property Relationships in π‐Conjugated Heterocyclic Poly(arylene alkylene) Anion‐Exchange Membranes for High‐Performance Water Electrolysis

Advanced Science, EarlyView.
From passive to active ion transport: π‐conjugated heterocycles reconfigure the hydration environment and microphase morphology of p‐terphenyl‐based anion‐exchange membranes, enabling fast hydroxide transport and high‐performance water electrolysis. ABSTRACT Anion‐exchange membrane water electrolysis (AEMWE) is a promising technology for sustainable ...

Structure and Biosynthesis of Mangotoxin Produced by the Plant Pathogen Pseudomonas syringae

Angewandte Chemie, EarlyView.
The structure of mangotoxin remained elusive for over two decades. Here, mangotoxin was isolated from the native producer, Pseudomonas syringae pv. syringae, and was determined to be an alkyne‐containing dipeptide. Mangotoxin inhibited the growth of multidrug‐resistant human pathogen Klebsiella pneumoniae.

Direct Access to Chiral Piperidines by Enantioselective HAT‐Initiated C(sp3)─H Oxidation

Angewandte Chemie, EarlyView.
The direct desymmetrization of piperidines is achieved through manganese‐catalyzed enantioselective α‐C(sp3)─H oxidation with hydrogen peroxide, affording versatile chiral N,O‐acetals in good yields and with high enantio‐ and diastereoselectivity. These intermediates provide access to diverse functionalized piperidines with retention of chirality ...
