Protein–Anthocyanin Interactions in Food Systems: A Reaction‐Network Perspective on Equilibria, Kinetics, and Degradation Pathways

ChemFoodChem, EarlyView.
Protein–anthocyanin interactions are reinterpreted beyond binding affinity through a reaction‐network perspective. Distinct protein classes modulate anthocyanin behavior through equilibrium shifts, matrix‐driven protection, self‐assembly, or covalent conjugation.

Mild C─F Activation of Azido(per)Fluoroalkanes

Chemistry – A European Journal, EarlyView.
Mild and selective activation of C(sp3)–F bonds in azido(per)fluoroalkanes using thiolates was developed, leading to novel functionalized azides. The reaction is initiated by nucleophilic attack of the sulfur atom to the terminal nitrogen of the azido group, followed by fluoride ion elimination.

Stereochemical Control in the Matteson Reaction

Chemistry – A European Journal, EarlyView.
The Matteson homologation is a highly versatile method for the stereoselective insertion of carbenoids into boronic esters. Through iterative application of the process, complex chiral molecules can be synthesized. The stereoselectivity of the reaction is determined by a chiral diol incorporated in the boronic ester.

Modular One‐Pot Access to π‐Expanded Tetrakis(Phenothiazinyl)‐Silanes With Broadly Tunable Redox and Emission Properties

Chemistry – A European Journal, EarlyView.
A library of 21 tetrakis(phenothiazinyl)‐substituted silanes with broadly variable substituent decoration, which are fully reversible multistage redox systems with intense tunable emission from deep blue to yellow–green (441–533 nm), was rapidly synthesized by bromine–lithium exchange/borylation–Suzuki coupling of tetrakis(4‐bromophenyl)silane or by ...

Rapid Access to Photoswitchable RNA Binders: Fluorination Enhances Protein Rescue by Exon Inclusion

Chemistry – A European Journal, EarlyView.
An adaptable approach, many light‐switchable RNA binders. We report a versatile strategy for rapidly synthesizing photoswitchable RNA binders. The ligands can target SMN2 pre‐mRNA, restoring the levels of the corresponding protein by exon‐inclusion rescue.

Cyclopropylamine‐Derived Distonic Iminium Radicals: Photoinduced Strategies in Chemo‐ and Stereo‐Selective Synthesis

Chemistry – A European Journal, EarlyView.
Cyclopropylamines have emerged as powerful photocatalytic building blocks. Upon light‐induced single‐electron oxidation, they undergo strain‐release ring opening to generate distonic iminium radicals that enable diverse transformations, including ring‐opening functionalization, formal [3 + 2] cycloadditions, radical cascades, and asymmetric bond ...

Mechanistic Insights Into Sustainable Catalytic Pyrolysis of Biomass‐Derived Ferulic Acid: The Role of Alumina Regeneration

Chemistry – A European Journal, EarlyView.
Surface‐bound ferulate phenolate complexes undergo styrene‐like polymerization on alumina, yielding a polymeric carbonaceous layer that progressively transforms into polyaromatic carbon domains with concomitant release of aromatic products, while parallel surface‐assisted decarboxylation produces 4‐vinylguaiacol. ABSTRACT A fundamental understanding of

New Insights into Poly(Dichlorophosphazene) Synthesis via Me3Si─N═PCl3 Polymerization: An Experimental and Theoretical Study

Chemistry – A European Journal, EarlyView.
Poly(dichlorophosphazene) synthesis via Me3Si─N═PCl3 polymerization was reinvestigated using quantum chemical calculations and experiments. A cationic initiator (Ph3PCl2) enables ambient‐temperature polymerization through chloride‐catalyzed cationic pathways involving dissociation, nucleophilic chloride attack, and chain‐propagating species formation ...

Hybrid Macrocyclic Peptides — Synthetic Strategies to Diversify and Cyclize Peptide Libraries in Phage Display Selections

Chemistry – A European Journal, EarlyView.
Hybrid macrocyclic peptides unite genetically encoded peptide libraries with the structural complexity of synthetic small molecules. This Review critically analyzes phage‐compatible cyclization and diversification chemistries, highlights emerging opportunities beyond traditional cysteine‐based approaches, and outlines how future advances may enable the
