4-Sulfanyl-1,2,3-triazole as a Powerful Ligand in CuAAC to Synthesize 1,4-Substituted 1,2,3-Triazoles Under Solvent-Free and Low Catalyst Loading [PDF]

open access: yesMolecules
4-Sulfanyl-1,2,3-triazole (L1) accelerated the solvent-free CuAAC efficiently with low catalyst loading (0.1 mol% for common azides and 1 mol% for sulfonyl azides). L1 exhibited higher catalytic activity compared to 1,4-substituted 1,2,3-triazole without

A practical flow synthesis of 1,2,3-triazoles [PDF]

open access: yesRSC Advances, 2022
Copper-on-charcoal is an excellent heterogeneous catalyst for the alkyne–azide cycloaddition reaction performed under continuous flow conditions. 2-Ynoic acids undergo decarboxylation/cycloaddition cascade giving triazoles bearing small alkyl chains.

1,2,3-Triazoles as Biomimetics in Peptide Science [PDF]

open access: yesMolecules, 2021
Natural peptides are an important class of chemical mediators, essential for most vital processes. What limits the potential of the use of peptides as drugs is their low bioavailability and enzymatic degradation in vivo. To overcome this limitation, the development of new molecules mimicking peptides is of great importance for the development of new ...

Synthesis of Deuterated 1,2,3-Triazoles [PDF]

open access: yesThe Journal of Organic Chemistry, 2012
The copper-catalyzed azide-alkyne cycloaddition (CuAAC) is a highly effective method for the selective incorporation of deuterium atom into the C-5 position of the 1,2,3-triazole structure. Reactions of alkynes and azides can be conveniently carried out in a biphasic medium of CH(2)Cl(2)/D(2)O, using the CuSO(4)/Na ascorbate system. The mildness of the
