Surface immobilization of biomolecules by click sulfonamide reaction

Chemical Communications, 2008
Alkyne-modified biomolecules can be immobilized site- and chemoselectively on sulfonylazide slides under very mild conditions by means of the click sulfonamide reaction.

Polymer “Clicking” by CuAAC Reactions

Macromolecular Rapid Communications, 2008
AbstractThe CuAAC “click” reaction has developed as one of the most useful and widely employed reactions in ligation within polymer chemistry. This is due to the unique properties of the Cu(I) catalysis which renders the reaction quantitative even at low concentrations, orthogonal with other chemistries and extremely robust.

Two-color emissive probes for click reactions

Chem. Commun., 2014
CuAAC is visualized using a BODIPY reaction system by the bathochromic shift of the fluorescence wavelength in ensemble and microscopy experiments. Reaction progress is correlated with chromophore elongation fading out disturbing background fluorescence.

Bioorthogonal Click and Release Reaction of Iminosydnones with Cycloalkynes

Angewandte Chemie, 2017
AbstractWe report the discovery of a new bioorthogonal click‐and‐release reaction involving iminosydnones and strained alkynes. This transformation leads to two products resulting from the ligation and fragmentation of iminosydnones under physiological conditions. Optimized iminosydnones were successfully used to design innovative cleavable linkers for

Trimerization of β-cyclodextrin through the click reaction

Carbohydrate Polymers, 2013
Triprop-2-ynyl benzene-1,3,5-tricarboxylate (A) is synthesized by the reaction of 1,3,5-benzenetricarbonyl trichloride with propargyl alcohol and (A) is clicked with mono-6-deoxy-6-azido-β-cyclodextrin (N3-β-CD) in the presence of copper(I) bromide catalyst. N3-β-CD has been prepared from β-cyclodextrin (β-CD) on treatment with toluenesulfonyl chloride

DACN-Based Switchable Fluorescent Click Reaction

The Journal of Organic Chemistry
The copper-free switchable fluorescent click reaction using 4,8-diazacyclononyne (DACN) and 3-azido-7-alkoxycoumarin was realized and applied to the conjugation of biomolecules. This new method using DACN has characteristics superior to those of the corresponding azadibenzocyclooctyne (DBCO) derivative in terms of fluorescence quantum yield and ...

Multiple “Click” Reactions on Porphyrins

2010
Im Rahmen der vorliegenden Arbeit wurde die 1,3-dipolare SHARPLESS Alkin-Azid Cycloaddition sehr erfolgreich auf die von JUX im Jahr 2000 vorgestellten ortho-benzylisch substituierten Tetraphenylporphyrinen übertragen. Durch diese Reaktion gelang es über 40 komplexe und anspruchsvolle Moleküle in sehr guter Ausbeute zu synthetisieren.
