Diels-Alder “Click” Reactions

Current Organic Chemistry, 2016
The Diels-Alder reactions can be classified as click reactions because of their simplicity and high yields. The Diels-Alder click reactions have been used for the preparation of complex macromolecules, such as hydrogels and polymers and also for labeling of various biological targets.

Clusters for alkyne-azide click reactions

Dalton Transactions, 2010
The clusters Ti(6)O(4)(OPr)(8)(OOC(CH(2))(2)C[triple bond]CH)(8) and [Zr(6)O(4)(OH)(4)(OOC(CH(2))(3)C[triple bond]CH)(12)](2) with acetylenic carboxylate ligands were prepared and structurally characterized in solution and in the crystalline state. Model reactions showed that they are suitable candidates for the formation of cluster-based inorganic ...

Chemoselective derivatization of a bionanoparticle by click reaction and ATRP reaction

Chemical Communications, 2007
Horse spleen apoferritin, the hollow protein shell derived from ferritin, a special biological nanoparticle, can be chemoselectively modified at the lysine residues, which affords a robust scaffold for further chemical reactions including Cu(i)-catalyzed azide-alkyne cycloaddition reaction and atom transfer radical polymerization reaction.

Intramolecular Nitrone Interrupted Click Reaction

Organic Letters
We document the intramolecular interception of a Cu-catalyzed azidoalkyne cycloaddition employing a suitably placed nitrone group, providing a simple route to the unprecedented spiro-polyheterocyclic scaffold. The reaction is comprised of a Cu-catalyzed [3 + 2]-cycloaddition of (2-azidoaryl)isatogen with a terminal alkyne and the intramolecular ...

Radical-mediated click-clip reactions

Science
Click reactions, which are characterized by rapid, high-yielding, and highly selective coupling of two reaction partners, are powerful tools in synthesis but are rarely reversible. Innovative strategies that reverse such couplings in a precise and on-demand manner, enabling a click-clip sequence, would greatly expand the technique’s versatility. Herein,

Heterovalent Click Reactions on DNA Origami

Bioconjugate Chemistry
Nucleic acid nanoparticles (NANPs) fabricated by using the DNA origami method have broad utility in materials science and bioengineering. Their site-specific, heterovalent functionalization with secondary molecules such as proteins or fluorophores is a unique feature of this technology that drives its utility.

Core functionalization of polydiacetylene micelles by a “click” reaction

Soft Matter, 2011
Diacetylene amphiphile bearing terminal alkyne moiety form micelles which can be further photopolymerized. Herein we address the covalent grafting of a fluorescent label within the micelles by a “click” reaction. Fluorescence experiments revealed that micelles act for the label as a protective shield from the bulk water.

Horseradish‐Peroxidase‐Catalyzed Tyrosine Click Reaction

ChemBioChem, 2017
AbstractThe efficiency of protein chemical modification on tyrosine residues with N‐methylluminol derivatives was drastically improved by using horseradish peroxidase (HRP). In the previous method, based on the use of hemin and H2O2, oxidative side reactions such as cysteine oxidation were problematic for functionalization of proteins selectively on ...
