Epipolythiodioxopiperazine‐Based Natural Products: Building Blocks, Biosynthesis and Biological Activities

ChemBioChem, Volume 23, Issue 23, December 5, 2022., 2022
Housing sulfur: Certain fungi produce diketopiperazine compounds with a transannular sulfur bridge. These so‐called epipolythiodioxopiperzines are toxic by non‐specifically interacting with intracellular proteins and contribute to fungal pathogenicity. Producer strains serve as bio‐pesticides but also question safety of food fermentation.

Developing Quasi‐Solid‐State Ether‐Based Electrolytes with Trifluorotoluylation Ionic Liquids for High Voltage Lithium Metal Batteries

Advanced Materials, EarlyView.
This study proposes molecular design strategies to develop trifluorotoluylation ILs that enable quasi‐solid‐state ether‐based electrolytes for high‐voltage LMBs. The designed ILs greatly enhance the oxidative stability of the electrolyte and effectively suppress the dissolution of transition metal ions, facilitating the formation of a LiF‐rich ...
