N‐Aryl Acridone Derivatives as Effective Catalysts for Energy Transfer Reactions

Chemistry – A European Journal, EarlyView.
Acridones derivatives have high triplet energy, are simple accessible, and could be used in challenging [2+2] ENT reactions. ABSTRACT Organic photocatalysts capable of promoting high‐energy triplet energy transfer (EnT) remain limited, particularly for demanding [2+2] photocycloaddition reactions.

Synthesis and Biological Evaluation of Well‐Defined M6P(n)‐Modified Glycopeptides for Targeted Protein Degradation

Chemistry – A European Journal, EarlyView.
A synthetic methodology has been developed to prepare multifunctional M6P and M6Pn ligands of different valency. The glycopeptides were conjugated to cetuximab and then examined to mediate cellular uptake of fluorescently labeled EGFRvIII. Only cetuximab modified by glycopeptides having 3 or 6 M6P or M6Pn residues demonstrated greater uptake.

Flipping the Card With Enantiodivergent Organocatalysis

Chemistry – A European Journal, EarlyView.
This minireview elaborates on recent organocatalytic strategies for achieving enantiodivergence—the ability to access both product enantiomers using a single chiral catalyst. It highlights how achiral stimuli, such as solvent polarity and chemical additives, along with minimal catalyst modifications, trigger stereochemical inversions in reactions ...

SO2 Transfer Enabled by an Easy‐to‐Handle Ionic Liquid

Chemistry – A European Journal, EarlyView.
Best of both worlds: The ionic liquid [NEt3Me][Cl(SO2)n] unites the atom economy and low cost of sulfur dioxide with the safety and applicability of common surrogates, streamlining SO2 transfer to access to 3‐sulfolenes, sulfonamides, and SuFEx reagents.

Precision Chemistry for Protein Lysine Modification

Chemistry – A European Journal, EarlyView.
Selective modification of lysine residues is challenging due to their similar intrinsic reactivity. Inspired by enzymatic recognition, ligand‐guided electrophiles enable site‐selective labeling and functionalization, while ligand‐guided catalyses achieve regioselective installation of bio‐relevant post‐translational modifications.
