Single‐Atom Iron‐Catalyzed Oxidative Esterification: From Methylarenes to the Upcycling of Polystyrene and Lignin‐Derived Feedstocks

Angewandte Chemie, EarlyView.
Heterogeneous iron‐catalyzed environmentally benign and sustainable CH‐oxidative esterification methodology has been developed for the synthesis of esters. This challenging reaction has been achieved by the rational design of specific single atom iron‐based catalyst with Fe‐N4 active centers, which empowered the oxidative esterification of methyl and ...

2‐Azaazulenium Hemicyanine Dyes for NIR‐II Multimodal Imaging and Combined Phototherapy

Angewandte Chemie, EarlyView.
A strategically engineered class of 2‐azaazulenium hemicyanines is developed, featuring bright fluorescence in the second near‐infrared (NIR‐II) window and multifunctional performance. SWJT‐OCH3 shows type I/II reactive oxygen species (ROS) generation and excellent photothermal activity.

Three Component Thio‐ and Carboboration of Alkynes: A Modular Route to Functionalised Bicyclic Boronates

Angewandte Chemie, EarlyView.
Three‐component thio‐ and carbo‐boration reactions to form functionalised benzoxaborinines and benzazaborinines are reported. The nucleophile scope includes thioethers, thiols, and (hetero)arenes. Mechanistic studies revealed a disparity between thioboration using thioethers and using thiols.

Color‐Pure Organic Luminophores: Characteristics, Definitions, Physical Basis and Fundamental Design Principles

Angewandte Chemie, EarlyView.
Color‐pure all‐organic emitters, i.e., with narrow spectral characteristics, are intensively studied for high‐definition organic LEDs and multi‐color bioimaging. In order to guide targeted materials design, this educative review discusses spectral characteristics, proper definitions and units, and the physical basis of spectral broadening, to distill ...

Exploring the biological impact of bacteria-derived indole compounds on human cell health: Cytotoxicity and cell proliferation across six cell lines

Toxicology Reports
Over the past two decades, research has increasingly focused on the interactions between diet, gut microbiota, and host organisms. Recent evidence suggests that tryptophan, an essential amino acid, can be metabolized by gut microbiota into indoles, which

Late‐Stage Functionalization of Peptides on the Solid Phase

Angewandte Chemie International Edition, EarlyView.
Peptide modifications are essential to control pharmacodynamic and pharmacokinetic properties of peptide drugs. Consequently, strategies that allow for efficient and rapid incorporation of non‐canonical modifications into peptides in parallel formats are highly sought after.

A Ruthenium‐(Ph‐BPE) Catalyst for Asymmetric Alkynylation of Fluoral: Enantioselection From 1 of 12 Fluxional Stereogenic‐at‐Ruthenium Complexes

Angewandte Chemie International Edition, EarlyView.
The first enantioselective alkynylations of aqueous fluoral are described. These processes are catalyzed by an iodide‐bound ruthenium‐(Ph‐BPE)‐catalyst; an octahedral metal complex that can exist as 12 diastereomeric‐at‐metal isomers. Calculations reveal that 2 of 12 stereoisomeric complexes account for 99.9% of the Boltzmann population and that ...
