A mild, scalable electrocatalytic method for direct lactonization of benzylic alcohols to phthalides using N‐hydroxyphthalimide as a redox mediator is reported. This metal‐free process proceeds via a phthalimide‐N‐oxyl‐mediated hydrogen atom transfer mechanism, shows broad scope with good to excellent yields, and enables late‐stage functionalizations ...

Unleashing the power of Ag(I)‐acetylides with LiCl/dimethyl sulfoxide (DMSO). The LiCl/DMSO mixture have an unexplored ability to dramatically increase the solubility of Ag(I)‐acetylides regardless of their molecular structure, which is explored to achieve high chemoselectivity in the Cu(I)‐catalyzed interrupted cycloaddition between organic azides, Ag(

New Quinoline-Based Heterocycles as Anticancer Agents Targeting Bcl-2
The Bcl-2 protein has been studied as an anticancer drug target in recent years, due to its gatekeeper role in resisting programmed cancer cell death (apoptosis), and the design of BH3 domain mimetics has led to the clinical approval of Venetoclax (ABT ...

Cyclooctyne-based reagents for uncatalyzed click chemistry: A computational survey [PDF]
With the goal of identifying alkyne-like reagents for use in click chemistry, but without Cu catalysts, we used B3LYP density function theory (DFT) to investigate the trends in activation barriers for the 1,3-dipolar cycloadditions of azides with various

Synthesis and evaluation of a novel fluorescent sensor based on hexahomotrioxacalix[3]arene for Zn²+ and Cd²+ [PDF]
A novel type of selective and sensitive fluorescent sensor having triazole rings as the binding sites on the lower rim of a hexahomotrioxacalix[3]arene scaffold in a cone conformation is reported.

A Polyoxometalate—Carbon Nanotube Enhanced Electrochemical Sensor for Aptamer‐Based Diagnostics
The high electroactive surface area of multi‐walled carbon nanotubes decorated with aptamer‐functionalized polyoxovanadate units enables a ≈1000‐fold increase in peak current response for a model diclofenac detection in aqueous solution compared to unmodified platinum microelectrodes.

Electroactive tetrathiafulvalene based pyridine-mono and -bis(1,2,3-triazoles) click ligands: synthesis, crystal structures and coordination chemistry [PDF]
Electroactive ligands picoline-1,2,3-triazole-5-DM-TTF and lutidine-bis(1,2,3-triazole-5-DM-TTF) are synthesized by click chemistry following the ruthenium catalyzed azide–alkyne cycloaddition strategy.

Global targeting of functional tyrosines using sulfur triazole exchange chemistry
Covalent probes serve as valuable tools for global investigation of protein function and ligand binding capacity. Despite efforts to expand coverage of residues available for chemical proteomics (e.g., cysteine and lysine), a large fraction of the ...

This study reveals that Arabidopsis telomere repeat binding proteins (TRBs) form two closely related complexes. These complexes mediate H3K4me3 demethylation and transcriptional repression through a positive feedback loop and cooperate with PEAT and PRC2 complexes to regulate multiple histone modifications and gene expression across the genome ...
