1,2,3-Triazoles. Part II. 4-Amino-5-aminomethyl-1,2,3-triazoles

Journal of the Chemical Society, Perkin Transactions 1, 1973
4-Amino-1-(and 2-)methyl-1,2,3-triazole-5-carbonitrile were made by acidic hydrolysis of 4-dimethylaminomethyleneamino-1-(and 2-)methyl-1,2,3-triazole-5-carbonitrile. These amino-nitriles, and also their known 3-methyl- and 3-benzyl-analogues, were hydrogenated to 4-amino-5-aminomethyl-1-methyl-1,2,3-triazole (1a) and its 2- and 3-methyl- and 3-benzyl ...

Synthesis of glucosylated 1,2,3-triazole derivatives

Carbohydrate Research, 1999
A series of potential bioactive compounds, 1-glucosyl-4-heterocyclyl-5-(p-substituted-phenyl)-1,2,3-triazoles , were synthesized. Highly stereoselective products were obtained in good yield. Primary activity screening showed that this type of N-glucosylic compound possessed antitumour and antiviral activities.

Method for Assigning Structure of 1,2,3-Triazoles

The Journal of Organic Chemistry, 2012
1,4-Disubstituted-1H-1,2,3-triazoles 1 can easily be distinguished from the isomeric 1,5-disubstituted-1H-1,2,3-triazoles 2 by simple one-dimensional (13)C NMR spectroscopy using gated decoupling. The C(5) signal of 1 appears at δ ∼120 ppm, while the C(4) signal of 2 appears at δ ∼133 ppm. Computational studies also predict the upfield shift of C(5) of

Structural basis of the impact sensitivities of 1-picryl-1,2,3-triazole, 2-picryl-1,2,3-triazole, 4-nitro-1-picryl-1,2,3-triazole, and 4-nitro-2-picryl-1,2,3-triazole

The Journal of Physical Chemistry, 1989
The isomeric pairs 1-picryl-1,2,3-triazole, 2-picryl-1,2,3-triazole and 4-nitro-1-picryl-1,2,3-triazole, 4-nitro-1-picryl-1,2,3-triazole differ dramatically in their impact sensitivity. Since these pairs of compounds have identical oxygen balance this strongly suggests that there is a difference in the decomposition mechanism.

A vibrational assignment for 1,2,3-triazole

Journal of the Chemical Society B: Physical Organic, 1969
I.r. spectra of 1,2,3-triazole in the vapour and liquid states and in solution are reported and discussed. From these, and by comparison with the spectra of other simple five-membered heterocycles, vibrational assignments are proposed. The i.r. spectra is satisfactorily interpreted in terms of an asymmetric structure.

Mass spectra of 1,2,3-triazoles

Journal of the Chemical Society, Perkin Transactions 1, 1979
The mass spectra of substituted 1,2,3-triazoles [RTR′, (1)](R′= H, CO2X, COR″, pyrazolyl, or isoxazolyl) are discussed. For a wide variety of structural types, P+ is always strong and [P+ 1]+ is often of significant intensity. Subsequent breakdown patterns are strongly dependent on the substituents R and R′.

1,2,3‐Triazoles in Peptidomimetic Chemistry

European Journal of Organic Chemistry, 2011
AbstractThe ability to synthesise small peptidomimetics that mimic the secondary structure of proteins is an ever expanding area of research directed at sourcing new medicinal agents and biological probes. A significant current challenge is to mimic protein epitopes under physiological conditions using small peptidomimetics that are easy to prepare ...

Azolyl-substituted 1,2,3-triazoles

Russian Journal of Organic Chemistry, 2016
Huisgen reaction of (E)-1,5-diarylpent-2-en-4-yn-1-ones and (E)-1,5-diarylpent-1-en-4-yn-3-ones afforded 1-aryl-3-(5-aryl-1H-1,2,3-triazol-4-yl)prop-2-en-1-ones and 3-aryl-1-(5-aryl-1H-1,2,3-triazol-4-yl)-prop-2-en-1-ones, respectively. (E)-1-Aryl-3-(5-phenyl-1H-1,2,3-triazol-4-yl)prop-2-en-1-ones reacted with hydrazine hydrate and phenylhydrazine to ...

Synthesis of 2H-1,2,3-Triazoles

2014
This chapter gives an overview of methods for the synthesis of NH- and N(2)-substituted 1,2,3-triazoles, their advantages, lacks, scope, and limitations. Moreover, it will give some insights on the reaction mechanisms and will explain how different conditions and structure substrates can influence the direction for reactions.
