Elucidating Ligand Exchange Dynamics of Hexacyanochromate‐Based Redox Mediators in Aqueous Iron‐Chromium Redox Flow Batteries

Angewandte Chemie, EarlyView.
The ligand exchange between cyanide and hydroxide in hexacyanochromate negolyte was caused by the disruption of coordination environment of the redox mediator ([Cr(CN)6]4‐/3−), with a critical factor as an elevated pH during electrochemical cycle. To mitigate this electrolyte co‐modulation strategy is introduced, optimizing the [OH−]/[CN−] ratios ...

Selective Chemo‐Divergent Hydrogenation of Ethylene Carbonate Enabled by Multi‐Functional Poly(Ionic Liquids)‐Stabilized Ru Nanoparticles

Angewandte Chemie, EarlyView.
A highly efficient and selective chemo‐divergent hydrogenation of cyclic carbonates is promoted by in situ generated poly(ionic liquid)‐stabilized ruthenium nanoparticles (Ru@PIL) catalysts. Under solvent‐free conditions, ethylene carbonate is transformed into either ethylene glycol and CH4 or EtOH and CO2, following a “direct hydrogenation” or a ...

The Chemistry and Biology of the Tetrodotoxin Natural Product Family

Angewandte Chemie International Edition, Accepted Article.
Tetrodotoxin is a neurotoxic marine alkaloid, first isolated in 1909 from pufferfish and named after the biological order tetraodontiformes. Since its structural elucidation in 1964, it has attracted the interest of synthetic organic chemists due to its exceptional polarity, complex architecture, and important biological activity.

Mechanochemical Strategies Applied to the Late‐Stage Modifications of Pharmaceutically Active Compounds

Angewandte Chemie International Edition, Accepted Article.
This review explores the potential of mechanochemistry in the late‐stage modification of active pharmaceutical ingredients (APIs), offering a comprehensive analysis of methods designed to transform structurally complex molecular scaffolds. By examining the scope, efficiency, and mechanistic aspects of these approaches, the review highlights protocols ...

Integrated Chemoenzymatic Synthesis of the mRNA Vaccine Building Block N1‐Methylpseudouridine Triphosphate

Angewandte Chemie International Edition, EarlyView.
Pseudouridine‐5′‐triphosphate (ΨTP) and its N1‐methylated derivative (m1ΨTP) are crucial components in mRNA vaccine technology. Here, an atom‐economic, high‐yielding biocatalytic route for ΨTP synthesis is presented. A new chemoenzymatic route for m1ΨTP synthesis was developed.
