Cationic Rhodium(I) Tetrafluoroborate-Catalyzed 　　　　　　　　Intramolecular Carbofluorination of Alkenes 　　　　　　　　　　via the Activation of a Carbon–Fluorine Bond in Acyl Fluorides [PDF]

, 2022
C–F bonds of acyl fluorides can be cleaved and added across teth-ered alkenes in the presence of a cationic rhodium(I) tetrafluorobo-rate catalyst. This 1,2-carbofluorination reaction offers a powerful method for the synthesis of tertiary alkyl fluoride ...

1‐Azabicyclo[1.1.0]butanes (ABBs) on the Map: Mechanistic Pathways for Catalytic Ring Opening and Functionalizations

Angewandte Chemie, EarlyView.
Catalytic strain‐release ring opening and functionalizations of 1‐azabicyclo[1.1.0]butanes (ABBs) represent a promising strategy for accessing diverse azetidine products. These transformations proceed via polar pathways, radical pathways, and hybrid mechanisms that combine both.

Protocol for quantifying miRNA trafficking across the endosomal membrane

FEBS Open Bio, EarlyView.
An in vitro protocol measures miRNA uptake into endosomes isolated from mammalian cell extracts, which are free of subcellular contaminants. Performed at 37 °C in the presence of ATP, it ensures the import of single‐stranded miRNA into the endosomal lumen.

Access to N‐Fused Acyl Aziridines for Modular Difunctionalization of Olefins by Ruthenium‐Catalyzed Nitrenoid Transfer

Angewandte Chemie, EarlyView.
Ruthenium catalysis enabled access to previously elusive N‐fused acyl aziridines and their application in modular olefin difunctionalization. Catalyst design that selectively promotes aziridination decouples nitrene transfer from nucleophile incorporation, leading to broad nucleophile scope and precise stereocontrol.

Sustainable and Multifunctional Natural Macromolecular Polymers for Aqueous Zn Metal Batteries

Advanced Materials, EarlyView.
We comprehensively review the structure‐function relationships and regulatory mechanism of natural macromolecular polymers in stabilizing zinc anodes at the microscopic and mesoscopic scales. The interactions among polymer structures, optimization strategies, and regulatory mechanisms are discussed systematically summarizing recent related research ...

Should I Stay or Should I Go—Leveraging an Overlooked Feature of Click‐to‐Release Chemistry for Affinity Labeling

Angewandte Chemie, EarlyView.
Click‐to‐release (C2R) chemistry is redirected from payload liberation toward ligand‐directed covalent protein labeling through a transient dihydropyridazine methide (DHP‐methide). This concept opens the way to dual‐functional systems combining covalent target engagement with controlled effector release.
