Pullulan-Graft-Polyoxazoline: Approaches from Chemistry and Physics

open access: yesMolecules, 2023
An approach to the preparation of pullulan-graft-poly(2-methyl-2-oxazoline)s based on Cu-catalyzed azide–alkyne cycloaddition with polyoxazoline-azide was applied.

Copper-catalyzed Z-selective synthesis of acrylamides and polyacrylamides via alkylidene ketenimines

open access: yesNature Communications, 2022
Alkylidene ketenimines are rarely reported, but synthetically useful, reactive intermediates. Here, the authors disclose a three-component reaction of alkyne, azide and water by cycloaddition, nitrogen extrusion, and carbene-assisted rearrangement, via ...

Toward Long-Term-Dispersible, Metal-Free Single-Chain Nanoparticles

open access: yesNanomaterials, 2023
We report herein on a new platform for synthesizing stable, inert, and dispersible metal-free single-chain nanoparticles (SCNPs) via intramolecular metal-traceless azide–alkyne click chemistry.

Direct Light-up of cAMP Derivatives in Living Cells by Click Reactions

open access: yesMolecules, 2013
8-Azidoadenosine 3′,5′-cyclic monophosphate (8-azido cAMP) was directly detected in living cells, by applying Cu-free azide-alkyne cycloaddition to probe cAMP derivatives by fluorescence light-up.

Synthesis of Novel C-2- or C-15-Labeled BODIPY—Estrone Conjugates

open access: yesMolecules, 2018
Novel BODIPY–estrone conjugates were synthesized via Cu(I)-catalyzed azide–alkyne cycloaddition (CuAAC). Estrone-alkynes or an estrone-azide as starting compounds were synthesized via Michael addition or Sonogashira reaction as key steps ...

Nitrogen-Based Linkers with a Mesitylene Core: Synthesis and Characterization

open access: yesMolecules, 2021
Mesitylene was used as a core in seven new tritopic nitrogen containing linkers. Three of the linkers, each containing three nitrile groups, were obtained through Suzuki, Sonogashira and Heck-type coupling reactions.
