We turned a triazole ring into a molecular mousetrap—snapping up amino groups for bioconjugation! 🧠💥
Super reactive, highly selective, and thiol-tolerant.
Great teamwork with Huadong Xu (Changzhou University)!

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: • onlinelibrary.wiley.com/doi/…
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•

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.

I am deeply humbled and honored to be part of the editor team of Organic Letters. I very much look forward to serving the journal and our organic community☺️
We are thrilled to announce that Prof. Gong Chen of Nankai University will be joining #OrgLett as an Associate Editor on December 1. Known for his work on metal-catalyzed C-H functionalization and on peptides and oligosaccharides, Gong may soon be handling your manuscript!
Our lucky streak continued! Formaldehyde can glue amine and guanidine together like a charm :) Thank Xiaosong Xue at Nankai and SIOC for the computational collaboration! pubs.acs.org/doi/10.1021/jac…
