Transformations of 1-(Oxiranylmethyl)-1,2,3-triazoles into 2-(Oxiranyl­methyl)-1,2,3-triazoles and Alkanenitriles [PDF]

Synlett, 2012
New reactions for the transformation of 1-(oxiranylmethyl)-1,2,3-triazoles into 2-(oxiranylmethyl)-1,2,3-triazoles or alkanenitriles were established. Successive treatment of the substrate with triflic acid and t-BuOH afforded 4,6-dihydro-5-hydroxy-1,3a,6a-triazapentalene derivative.

Cu(I)‐Catalyzed Interrupted Cycloaddition Between Azides, Ag(I)‐Acetylides, and Diorganoyl Dichalcogenides

Advanced Synthesis &Catalysis, EarlyView.
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(

Acidogenesis‐Propelled Coordination Transition in Light‐Triggered Fe‐Polyphenol Polymer for Reactive Oxygen Species‐Augmented Antitumor Therapy

Advanced Science, EarlyView.
A novel iron‐polyphenol‐photoacid coordination polymer (FeBPs) is designed to achieve red light‐triggered external acidification and internal coordination regulation, where this light‐controlled acidification induces coordination changes that enhance Fe active site exposure and provide H+ for beneficial Fe3+/Fe2+ conversion, thereby accelerating ROS ...

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 ...

Antitrypanosomal and antileishmanial activity of prenyl-1,2,3-triazoles [PDF]

MedChemComm, 2017
A series of prenyl 1,2,3-triazoles were prepared from isoprenyl azides and different alkynes. Most of the compounds were active against T. cruzi and L. donovani.

Antimicrobial studies of unsymmetrical bis-1,2,3-triazoles [PDF]

Organic and Medicinal Chemistry Letters, 2012
Aryl azides were treated with allenylmagnesium bromide to generate 1,5-disubstituted butynyl 1,2,3-triazoles in a domino fashion, which upon Cu(I) catalyzed 1,3-dipolar cycloaddition with aryl azides afforded novel bis-1,2,3-triazoles in quantitative yields.

Stimuli‐Responsive Supramolecular Polymers of Mono‐ and Bis‐triazolylphenylazoaniline‐Functionalized Copillar[5]Arenes: With Distinctive Binding Modes

Chemistry – An Asian Journal, EarlyView.
Mono‐ and bis‐functionalized copillar[5]arenes 1 and 2 form pH‐ and photo‐responsive supramolecular polymers. Protonation of 1 enhances polymerization (1‐H), differing from neutral 2, which forms a 1:1 complex with DMP5 via cavity binding. Polymerization and morphology are tunable by pH and light, as shown by NMR, UV–vis, and FE‐SEM analyses.
