Geminal Difunctionalization of Ketones via C─S Bond Insertion of Photogenerated Donor–Donor Diazo Compounds

open access: yesAngewandte Chemie International Edition, EarlyView.
Geminal difunctionalization of readily available building blocks provides rapid access to molecular complexity. This work introduces a strategy for installing two distinct functional groups on a carbonyl carbon by transforming it into a donor–donor diazo compound, enabling both batch and flow applications with broad solvent compatibility.

Aziridination of a Single Carbon Atom in Alkenes via Energy Transfer Catalysis

open access: yesAngewandte Chemie International Edition, EarlyView.
Contrary to traditional alkene aziridination via (formal) nitrene transfer, we herein report a strategy that achieves intermolecular aziridination of a single alkene carbon atom and installs an additional group at the other. Enabled by metal‐free energy transfer (EnT) catalysis, alkenyl boronates and silanes are transformed into reactive intermediates ...

Discrimination of Lipid Hydroperoxide Positional Isomers Using SFC–MS/MS With Sodium Ion: Its Application to Evaluating the Oxidation Mechanisms of Oxidized Oils

open access: yesJournal of the American Oil Chemists' Society, EarlyView.
ABSTRACT Advanced lipid profiling relies on liquid chromatography–tandem mass spectrometry (LC–MS/MS), but long analysis times remain a challenge. Supercritical fluid chromatography (SFC)–MS/MS using supercritical carbon dioxide offers a faster and more environmentally friendly alternative.

Light‐Responsive Carbon Dots with Photochromism and Excitation‐Dependent Room Temperature Phosphorescence

open access: yesAdvanced Physics Research, EarlyView.
A light‐responsive system with photochromism and excitation‐dependent phosphorescence was constructed by microwave synthesis of nitrogen‐doped carbon dots(N‐CDs), which provides insights into the design and synthesis of CDs with multifunctional optical properties, promoting the application expansion of intelligent responsive materials in the fields of ...

Bacterial Pigments as Potential Antitumor Agents Against Gastrointestinal Cancers: A Comprehensive Systematic Review

open access: yesBiotechnology and Applied Biochemistry, EarlyView.
ABSTRACT Gastrointestinal cancers (GICs) constitute one of the leading causes of cancer‐related morbidity and mortality worldwide. Despite currently available therapeutic strategies, new approaches and procedures are needed for their prevention and treatment.
