We’ve been dreaming of this type of conjugation chemistry for years—and finally, a simple fix to a stubborn problem, all thanks to just a tiny drop of CS₂. Minimalist chemistry is the new gold. ✨
@gongchenlab have been hunting for ways to crosslink two different amines for conjugation: turns out that just a drop of CS₂ in air delivers great results! Read on in their Research Article: •

A huge thank you to our amazing guest editors, Masayuki Inoue, Lara Malins @Malins_lab, and Hans Renata @hanzyduzit, for organizing this OL special issue on radical-mediated reactions! Special thanks to Steve Ritter and Matt Saucier for your invaluable support.
Special Issue alert! 🚨 This one is truly •radical• https://t.co/1brknWrgqF This VSI highlights the state of the art in radical reaction development and the strategic incorporation of radical reactions in the construction and modification of important molecules.

HFIP's magic shines again, enabling peptide stapling with alpha-ketoaldehydes through unique imidazolium linkers, outperforming natural “glycation” processes. We proposed HFIP aggregates act as a proton shuttle for efficient deacylative C--C cleavage.

We are grateful for the swift publication of this work in @NatureSynthesis and the outstanding editorial assistance received!
N-glycoside synthesis, a tough nut to crack, is now approachable with our new light/Cu catalysis method, allowing N-glycosidic bond formation under mild conditions with exceptional water tolerance and unique chemoselectivity. Another fruitful collaboration with MJ Koh @MJKoh87.

Two simple reagents, HCHO and hexafluoroisopropanol (HFIP), unleash new chemical magic! HCHO effectively “sucks” the alpha C-H bond from common alkyl amines in HFIP solvent, enabling hydride liberation without metals or light. It works for complex systems, too.
