A Radical‐Based, Transition Metal‐Free Approach for Diaryl Ketone Synthesis

open access: yesChemSusChem, EarlyView.
A sustainable and scalable one‐pot route to diverse diaryl ketones is described, proceeding via a distinctive radical process between aryl halides and benzonitriles, initiated by KOtBu/DMA and driven by air as the sole oxidant. Free from transition metals, peroxides, and carbon monoxide, this catalyst‐free and selective method exhibits broad functional

Redefining the Skin Barrier: A Microbiome‐Integrated Multilayered Defense Model

open access: yesBarrier Immunity, EarlyView.
ABSTRACT The skin constitutes a dynamic interface orchestrating a sophisticated multilayered defense system comprising physical, chemical, immune, and microbial barriers. This review synthesizes current understanding of the structural and functional integration of these barriers, emphasizing their synergistic interactions in maintaining cutaneous ...

Transition Metal‐Free Ortho‐Deuteration of Electron‐Deficient N‐Heteroarenes

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
Herin, the metal‐free, selective deuteration of electron‐deficient N‐heteroaromatics is reported using O‐carbamate and carboxamide ortho‐directing groups (DGs), lithium 2,2,6,6‐tetramethylpiperidide as the base, and D2O as a green source of D+. The substrate scope includes 10 small molecule N‐heteroaromatic compounds and two pharmaceutically relevant ...

1,3‐Diazetidin‐2‐Ones: Synthetic Approaches and Therapeutic Promise within the Aza‐β‐Lactam Family

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
This review explores the synthesis, reactivity, and therapeutic potential of 1,3‐diazetidin‐2‐ones—an underexplored class of aza‐β‐lactams. Emphasis is placed on synthetic challenges, emerging methodologies, and their promise as β‐lactamase‐resistant scaffolds in medicinal chemistry. 1,3‐diazetidin‐2‐ones, overlooked members of the aza‐β‐lactam family,

Cytotoxicity of 19 Pesticides in Rainbow Trout Gill, Liver, and Intestinal Cell Lines

open access: yesEnvironmental Toxicology and Chemistry, EarlyView.
Abstract The rainbow trout gill cell line (RTgill‐W1), via test guideline 249 of the Organisation for Economic Co‐operation and Development, has been established as a promising New Approach Methodology, although to advance confidence in the method more case studies are needed that: 1) expand our understanding of applicability domains (chemicals with ...
