‘Click’ glycosylation of peptides through cysteine propargylation and CuAAC

Bioorganic & Medicinal Chemistry, 2014
'Click' glycosylation of cysteine-containing peptides were carried out in good yield by Copper(I)-catalyzed Azide-Alkyne Cycloaddition (CuAAC). For that peptides were functionalized though direct propargylation of the cysteine residue allowing their use in CuAAC with suitable free or protected azido sugars of gluco, manno and galacto configuration ...

Fluktuierender Kupferacetylid‐Cluster in der CuAAC‐Katalyse

Angewandte Chemie, 2015
AbstractEin molekular definierter Kupferacetylidcluster mit N‐heterocyclischen Carben‐Steuerliganden (NHC) wurde zum ersten Mal unter sauren Reaktionsbedingungen hergestellt. Dieser Cluster ist der erste molekulare Kupferacetylid‐Komplex, der eine hohe Aktivität in der Kupfer‐katalysierten Azid‐Alkin‐Cycloaddition aufweist, bei Essigsäurezusatz sogar ...

Star‐Shaped Polyacrylates: Highly Functionalized Architectures via CuAAC Click Conjugation

Macromolecular Rapid Communications, 2009
AbstractWell‐defined functional star‐shaped polymer structures with up to 29 arms have been successfully synthesized by the combination of atom transfer radical polymerization (ATRP) and click chemistry. First, azide end‐functionalized poly(isobornyl acrylate) (PiBA) star‐shaped polymers were prepared by successive ATRP and bromine substitution ...

Efficient CuAAC click formation of functional hemoglobin bis-tetramers

Chemical Communications, 2010
A cross-linked hemoglobin bis-tetramer with oxygenation properties appropriate for a red cell substitute is produced by CuAAC conjugation of a dialkyne and two equivalents of an azide of β,β-cross-linked hemoglobin. The latter is formed efficiently by the aminolysis of the 3,5-dibromosalicylate ester of the β-82-β'-82-bis trimesyl amide of human ...

Copper catalysed azide–alkyne cycloaddition (CuAAC) in liquid ammonia

Organic & Biomolecular Chemistry, 2012
Copper(I) catalysed azide-alkyne cycloaddition reactions (CuAAC) occur smoothly in liquid ammonia (LNH(3)) at room temperature to give exclusively 1,4-substituted 1,2,3-triazoles with excellent yields (up to 99%). The CuAAC reactions in liquid ammonia require relatively small amounts of copper(I) catalyst (0.5 mole%) compared with that in conventional ...

Cyclic polystyrene topologies via RAFT and CuAAC

Polymer Chemistry, 2012
Cyclic polymer have attracted interest due to their different self-assembly behavior and physical properties compared to their linear counterparts with the same molecular weight. There are only a few examples of using polymer made by RAFT to create cyclic polymers, and no reports of coupling these cyclic polymers together to form stars.
