Electrochemical investigation of radical‐radical recognition in viologen‐based ditopic structures

Responsive Materials, EarlyView.
The so‐called “blue box” is one of the most studied macrocycles. Yet, functionalized macrocycles of this type are rarely investigated. This work describes the radical‐radical recognition properties of ditopic structures, including functionalized blue‐box macrocycles.

Oligonucleotides Post‐Synthetic Modifications: An Overview of Clickable Nucleoside Phosphoramidites Suitable for Solid‐Phase Synthesis

ChemBioChem, Volume 27, Issue 13, 14 July 2026.
Clickable nucleoside phosphoramidites can be incorporated into oligonucleotides via solid‐phase synthesis (SPOS), enabling rapid and site‐specific post‐functionalization using bioorthogonal reactions. This review highlights their design, synthetic accessibility, and SPOS incorporation requirements, along with the kinetics and efficiency of post ...

Phenyl 1,2,3-triazole-thymidine ligands stabilize G-quadruplex DNA, inhibit DNA synthesis and potentially reduce tumor cell proliferation over 3'-azido deoxythymidine.

PLoS ONE, 2013
Triazoles are known for their non-toxicity, higher stability and therapeutic activity. Few nucleoside (L1, L2 and L3) and non-nucleoside 1,2,3-triazoles (L4-L14) were synthesised using click chemistry and they were screened for tumor cell cytotoxicity ...

“Click” Synthesis of Nonsymmetrical Bis(1,2,3-triazoles)

Organic Letters, 2010
Unsymmetrically 1,1'-disubstituted 4,4'-bis-1H-1,2,3-triazoles 4 have been prepared from 4-ethynyl-1,2,3-triazoles 5 and azides. Following a "double-click" strategy, two complementary approaches were implemented for the preparation of the key 4-ethynyltriazole intermediates 5: (a) the stepwise Swern oxidation/Ohira-Bestman alkynylation of readily ...

Toward Sustainable Carbonylation Reactions Enabled by CO Surrogates in Green Solvents

ChemSusChem, Volume 19, Issue 13, 14 July 2026.
Carbonylation reactions offer a sustainable route to valuable carbonyl compounds. This review highlights methodologies that exploit carbonylative coupling to drastically enhance process sustainability, avoiding the direct use of CO through CO surrogates and promoting syntheses in green solvents potentially derived from renewable and sustainable sources.

An Overview of Pterin Analysis in Biological Samples: From Occurrence and Properties to Sample Pretreatment Combined With Hyphenated Separation Techniques

Journal of Separation Science, Volume 49, Issue 7, July 2026.
ABSTRACT Pterins are a structurally diverse group of biologically active compounds within the pteridine family, with key roles in pigmentation, redox metabolism, light sensing, and cellular signaling across a wide range of organisms. Their quantification in biological samples is analytically demanding due to their high polarity, chemical instability ...
