Microwave assisted metal-free approach to access 1,2,3-triazoles through multicomponent synthesis
The work illustrates multicomponent reaction of aldehydes, nitroalkanes and sodium azide for the metal-free synthesis of N-unsubstituted-1,2,3-triazoles using anthranilic acid as an organocatalyst under microwave irradiation. This is the first ever green

This study describes the synthesis and antioxidant activity of new 1,4-disubstituted 1,2,3-triazoles. These compounds were generated semi-synthetically using the Cu(I)-catalysed azide-alkyne cycloaddition (CuAAC) reaction between ethyl 2-azidoacetate and

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

1,2,3-Triazoles as Amide-bond Surrogates in Peptidomimetics
1,2,3-Triazoles represent a class of heterocycles with interesting properties for application in peptide sciences since they closely resemble amide bonds while being stable to enzymatic degradation.

Enantiomer stability of atropisomeric 1,5-disubstituted 1,2,3-triazoles
The synthesis and characterisation of axially chiral atropisomeric 1,5-disubstituted 1,2,3-triazoles is reported. Molecules designed to display restricted rotation about 1,2,3-triazole N-1-aryl or 1,2,3-triazole C-5-aryl bonds were investigated by ...

Rapid progress in the synthetic application of benzotriazole derivatives in the last 20 years has resulted in over 1000 scientific papers on the subject. This fact is reflected in Section 5.01.7, which involves almost a half of the volume of this chapter. The section is arranged according to hybridization of the C-α atom and atomic numbers of the atoms

A library of 1,2,3-triazoles was synthesized from diverse alkynes and azides using catalytic amounts of silver chloride instead of copper compounds. In addition, a novel “abnormal” silver N-heterocyclic carbene complex was tested as catalyst in this ...

Palladium-Catalyzed C–H Arylation of 1,2,3-Triazoles
Palladium(II) acetate, in combination with triphenylphosphine, catalyzes direct arylation of 1,4-disubstituted 1,2,3-triazoles effectively. This C–H arylation reaction provides facile access to fully substituted triazoles with well-defined regiochemistry.
