Substrate‐Controlled Enantiodivergence in Ni‐Catalyzed Access to Phosphorylated Oxindoles With Quaternary Stereocenters

open access: yesAngewandte Chemie, EarlyView.
An efficient, enantiodivergent synthesis of phosphorylated oxindoles with quaternary stereocenters is achieved via a nickel‐catalyzed intermolecular Heck‐phosphorylation cascade. Employing a single chiral catalyst, either product enantiomer is selectively accessed simply by changing the alkene leaving group. DFT calculations trace this stereodivergence

Hematoma Interleukin‐1 Receptor Antagonist Concentrations Predict Long‐Term Outcome in Acute Human Intracerebral Hemorrhage

open access: yesAnnals of Neurology, EarlyView.
Objectives The interleukin (IL)‐1, IL‐6, and C‐reactive protein (CRP) pathway is central to the immune response after intracerebral hemorrhage (ICH). We tested for associations between hematoma and plasma cytokine concentrations and patient outcomes in Minimally Invasive Surgery Plus Rt‐PA for ICH Evacuation Phase III (MISTIE III) participants ...

Supramolecular Modulation of Photoinduced Charge Transfer: Tuning Between Tunneling and Incoherent Hopping

open access: yesAngewandte Chemie, EarlyView.
Molecular recognition guest binding can comprehensively modulate photoinduced charge‐transfer dynamics in the cyclophane host, including charge separation and recombination, via coherent superexchange and incoherent hopping. Unlike covalent donor–bridge–acceptor systems, this supramolecular approach avoids tedious syntheses and offers precise tuning of

Monoallelic POLR3A Variants Cause Early‐Onset Peripheral Neuropathy

open access: yesAnnals of Neurology, EarlyView.
Objective Biallelic variants in genes encoding the RNA polymerase III complex (Pol III) cause a spectrum of neurological disorders primarily affecting the central nervous system. Monoallelic variants have been reported in the POLR3B subunit only, associated with neurodevelopmental disorder, epilepsy, and peripheral neuropathy.

Entropy‐Stabilized Aluminate Catalysts That Break the Activity–Stability Tradeoff in CF4 Hydrolysis

open access: yesAngewandte Chemie, EarlyView.
Entropy‐stabilized aluminate breaks the activity–stability tradeoff in CF4 hydrolysis by combining a multication aluminate framework with an entropy‐stabilized lattice. An electron‐deficient Al–O environment is F‐philic but O‐phobic, enabling C–F activation while suppressing H2O poisoning. Under steam‐rich, strongly fluorinating conditions, the entropy‐

Räumliche Entwicklung von Koks in ZSM‐5‐Katalysatoren während der Umwandlung von Methanol in Kohlenwasserstoffe, aufgezeigt durch in‐situ‐Röntgen‐Photoelektronenspektroskopie

open access: yesAngewandte Chemie, EarlyView.
Oberfläche enthüllt: Verkokung ist die zentrale Ursache für die Deaktivierung von Zeolithkatalysatoren. Mithilfe von In‐situ‐XPS in Verbindung mit ergänzenden Methoden identifizieren wir Unterschiede in der Bildungskinetik und Zusammensetzung von Oberflächenkoks auf industriell relevanten ZSM‐5‐Katalysatoren während der MTH‐Umwandlung und zeigen damit ...
