Click Triazoles for Bioconjugation [PDF]

, 2012
Click Chemistry is a set of rapid, selective and robust reactions that give near-quantitative yield of the desired product in aqueous solutions. The Cu(I)-catalyzed azide-alkyne cycloaddition (CuAAC) that forms 1,4-disubstituted triazoles is a prototypical example of click chemistry that features exquisite selectivity and bioorthogonality-that is, non ...

Synthesis of 1‑Cyanoalkynes and Their Ruthenium(II)-Catalyzed Cycloaddition with Organic Azides to Afford 4‑Cyano-1,2,3-triazoles

, 2018
A new method to convert terminal alkynes under relatively mild conditions to 1-cyanoalkynes using in situ formed cyanogen is described. 1-Cyanoalkynes have a higher reactivity than terminal alkynes in the ruthenium­(II)-catalyzed regiospecific azide ...

Enantioselective Rh-Catalyzed Azide-Internal-Alkyne Cycloaddition for the Construction of Axially Chiral 1,2,3-Triazoles

, 2022
Significant advances have been achieved for the construction of chiral skeletons containing 1,2,3-triazoles via transition-metal-catalyzed asymmetric azide–alkyne cycloaddition; however, most of them have been limited to terminal alkynes in the synthesis

Fast and Efficient Synthesis of Fluoro Phenyl 1,2,3-Triazoles via Click Chemistry with Ultrasound Irradiation and Their Biological Efficacy Against Candida albicans

Organics
Several fluoro phenyl triazoles were synthesized using click chemistry between fluoro phenyl azides and phenyl acetylene. Under ultrasound irradiation, this synthetic procedure was performed with Cu (I) in the presence of 1,10-phenanthroline.

Stabilizing Functional Nucleic Acids for Real‐Sample Diagnostics

Angewandte Chemie, EarlyView.
Functional nucleic acids enable programmable real‐sample diagnostics, but often lose function in complex biological matrices. This review highlights four stabilization levers—chemical, topological, architectural, and microenvironment/interface engineering—that preserve aptamer and DNAzyme performance in saliva, serum, urine, and stool, reframing ...
