Mechanochemical Amidation Mediated by 1,1’‐Oxalyldiimidazole for the Synthesis of Agrochemicals

Chemistry – A European Journal, Volume 32, Issue 34, 11 September 2026.
Mechanochemical amidation using 1,1'‐oxalyldiimidazole (ODI) overcomes limitations of 1,1’‐carbonyl diimidazole (CDI) as coupling agent by enabling the efficient mechanochemical synthesis of three marketed agrochemicals from deactivated carboxylic acids.

Precision Chemistry for Protein Lysine Modification

Chemistry – A European Journal, Volume 32, Issue 34, 11 September 2026.
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.

Copper‐Catalyzed α‐Carbamoylation of Cyclic β‐Ketoesters

European Journal of Organic Chemistry, Volume 29, Issue 34, 11 September 2026.
Cu(II) salt‐catalyzed reaction of cyclic β‐ketoesters with isocyanates afforded hitherto inaccessible α‐substituted β,β’‐dicarbonyl amides possessing an all‐carbon quaternary center. A copper‐catalyzed, base‐free α‐carbamoylation of cyclic β‐ketoesters with isocyanates has been developed.

Durch anomere Amide ermöglichte divergente Synthese unsymmetrischer Harnstoffe, Carbamate, Thioester und Amide aus Aldehyden

Angewandte Chemie, Volume 138, Issue 37, 7 September 2026.
Eine divergente Aldehyd‐Funktionalisierungssequenz, ermöglicht durch ein anomeres Amid, erlaubt den Ein‐Topf‐Zugang zu unsymmetrischen Harnstoffen, Carbamaten, Thiocarbamaten, Thioestern und Amiden. Entscheidend für diese Transformation ist die Bildung von N‐Boc‐Hydroxamat‐Intermediaten, die als Plattformen für eine orthogonale Aktivierung über Lossen ...

Anomeric Amide Enabled Divergent Synthesis of Unsymmetrical Ureas, Carbamates, Thioesters, and Amides From Aldehydes

Angewandte Chemie International Edition, Volume 65, Issue 37, 7 September 2026.
An anomeric amide‐enabled divergent aldehyde functionalization sequence provides one‐pot access to unsymmetrical ureas, carbamates, thiocarbamates, thioesters, and amides. Key to this transformation is the formation of N‐Boc‐hydroxamate intermediates, which serve as platforms for orthogonal activation via Lossen‐type rearrangements, single‐electron ...

A Chemical Framework for Engineering Extracellular Vesicles’ Biointerface to Advance Precision Therapeutics

Advanced Materials, Volume 38, Issue 52, 16 September 2026.
Extracellular vesicles (EVs) are cell‐derived nanoparticles that mediate intercellular communication through their dynamic biointerfaces. Owing to their intrinsic biological functions, EVs have emerged as promising platforms for biomedical applications.
