Synthesis, anti-bacterial and anti-protozoal activities of amidinobenzimidazole derivatives and their interactions with DNA and RNA. [PDF]

open access: yes, 2018
Amidinobenzimidazole derivatives connected to 1-aryl-substituted 1,2,3-triazole through phenoxymethylene linkers 7a-7e, 8a-8e, and 9a-9e were designed and synthesised with the aim of evaluating their anti-bacterial and anti-trypanosomal activities and ...

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

open access: yesSynlett, 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.

Diazo Transfer From Nitrous Oxide Employing Phosphorus Ylides

open access: yesAngewandte Chemie, EarlyView.
A phosphorus ylide‐mediated strategy achieves the direct fixation of nitrous oxide (N2O) to access diazo compounds, which after intra‐ or intermolecular trapping, afford N2‐containing organic building blocks. This approach provides an alternative to hazardous diazo‐transfer reagents and establishes N2O fixation as a sustainable methodology.

Radiosynthesis of 5-[18F]Fluoro-1,2,3-triazoles through Aqueous Iodine–[18F]Fluorine Exchange Reaction

open access: yesMolecules, 2021
In this report, a simple and efficient process to achieve fluorine-18-labeled 1,2,3-triazole is reported. The heteroaromatic radiofluorination was successfully achieved through an iodine–fluorine-18 exchange in an aqueous medium requiring only trace ...

Click Chemistry: 1,2,3‐Triazoles as Pharmacophores [PDF]

open access: yesChemistry – An Asian Journal, 2011
AbstractThe copper(I)‐catalyzed 1,2,3‐triazole‐forming reaction between azides and terminal alkynes has become the gold standard of ‘click chemistry’ due to its reliability, specificity, and biocompatibility. Applications of click chemistry are increasingly found in all aspects of drug discovery; they range from lead finding through combinatorial ...

Reduced Symmetry Metal–Organic Cage‐to‐Framework Materials

open access: yesAngewandte Chemie, EarlyView.
A series of Ag(I) MOFs was synthesised from organic cages of varying structure and symmetry as linkers. Minor variations in the cage linkers were shown to significantly influence the structures of the resulting MOFs. This work represents the first incorporation of reduced symmetry (including chiral), intrinsically porous building blocks into MOFs, and ...

Synthesis of Biologically Relevant 1,2,3- and 1,3,4-Triazoles: From Classical Pathway to Green Chemistry

open access: yesMolecules, 2021
Green Chemistry has become in the last two decades an increasing part of research interest. Nonconventional «green» sources for chemical reactions include micro-wave, mechanical mixing, visible light and ultrasound.
