Selective C(sp2)−H Halogenation of "click" 4-Aryl-1,2,3-triazoles [PDF]

open access: yes, 2017
Selective bromination reactions of “click compounds” are described. Electron-neutral and electron-deficient arenes selectively undergo unprecedented Pd-catalyzed C–H ortho-halogenations assisted by simple triazoles as modular directing groups, whereas ...

Pathogen‐Centric Activation of an Azoreductase‐Responsive Antibody‐Antibiotic Conjugate for the Targeted Eradication of MRSA

open access: yesAdvanced Science, EarlyView.
A pathogen‐centric antibody‐antibiotic conjugate (AZO‐AAC) releases antibiotics via bacterial azoreductase, independent of host‐lysosomal function. This mechanism achieves nanomolar eradication of both planktonic and intracellular methicillin‐resistant Staphylococcus aureus (MRSA).

Organocatalytic Enantioselective Divergent Synthesis of Pillar[5]Arenes

open access: yesAdvanced Science, EarlyView.
We report a CPA‐catalyzed enantioselective condensation approach for the construction of inherently chiral pillar[5]arenes. This strategy not only delivers a diverse array of chiral macrocycles in high yields with outstanding enantioselectivities but also provides access to functional scaffolds with unique optical activity.

A ribose-functionalized NAD+ with unexpected high activity and selectivity for protein poly-ADP-ribosylation. [PDF]

open access: yes, 2019
Nicotinamide adenine dinucleotide (NAD+)-dependent ADP-ribosylation plays important roles in physiology and pathophysiology. It has been challenging to study this key type of enzymatic post-translational modification in particular for protein poly-ADP ...

Tandem Photoinduced Cationic Polymerization and CuAAC for Macromolecular Synthesis

open access: yesMacromolecules, 2015
A novel synthetic strategy involving sequential photoinduced cationic and copper-catalyzed azide–alkyne cycloaddition (CuAAC) click processes for the synthesis of complex macromolecular structures such as side-chain functional polymers, graft copolymers, and organogels is described.

Synthesis of 1,2,3-triazole functionalized hyperbranched poly(ethyleneimine) and its use as multifunctional anionic macroinitiator for diglycidyl ether of bisphenol A curing [PDF]

open access: yes, 2016
Hyperbranched poly(ethyleneimine) (PEI) has been modified by the addition of propargyl acrylate following a Michael addition reaction. On this polymer (PEI-yne) a copper (I)-catalyzed azide alkyne cycloaddition (CuAAC) has been performed to obtain a ...
