Copper(II/III) Redox Couple Enables C─H Methylation via a Radical Mechanism Analogous to SAM Enzymes

Angewandte Chemie, EarlyView.
Biological C–H methylation proceeds through radical pathways mediated by one‐electron redox cofactors, yet no synthetic model has reproduced this reactivity. Here, we report the first isolable Cu(II/III)–methyl complexes that mediate C–H methylation through hydrogen atom transfer and methyl radical rebound.

Stereodivergent C‐(Hetero)Aryl Glycosylation by Nickel‐Catalyzed Redox‐Neutral Cross‐Coupling of Glycosyl Sulfonyl Hydrazides

Angewandte Chemie, Volume 138, Issue 34, 17 August 2026.
A nickel‐catalyzed C–C cross‐coupling protocol employing bench‐stable glycosyl sulfonyl hydrazides as practical glycosyl radical precursors is reported. A variety of (hetero)aryl iodides underwent cross‐coupling under redox‐neutral conditions to afford structurally diverse unprotected C‐(hetero)aryl glycosides.

A Novel Class of “Super‐Strained” Spiro Heterocycles: Gateway to 1‐Azaspiro[3.3]heptane Derivatives, and Biological Validation

Angewandte Chemie International Edition, EarlyView.
A new class of “super‐strained” spiro heterocycles—spirocyclic 1‐azabicyclo[1.1.0]butanes—was synthesized via insertion of cyclobutane‐, oxetane‐, and azetidine‐containing sulfonium reagents into substituted azirines. The stability of this new class of compounds was studied.

Comprehensive in vitro profiling of traditional and emerging stimulants at monoamine transporters and the 5‐HT2A receptor

British Journal of Pharmacology, EarlyView.
A pharmacological profiling of 58 synthetic stimulants of various classes at dopamine, norepinephrine, and serotonin transporters and the 5‐HT2A receptor, most showing distinct class‐dependent profiles, with some indicating a high abuse potential. Background and Purpose New psychoactive substances (NPSs) often emerge on the illicit drug market with ...

Harnessing benzamides as plant stress inhibitors, growth promoters and in management of crop resilience—A review

Plant Biology, EarlyView.
Benzamides boost crop resilience by inhibiting poly(ADP‐ribose) polymerase (PARP) to enhance stress tolerance and, through their antimicrobial, herbicidal, and insecticidal derivatives, they offer broad protection for sustainable crop improvement. Abstract Benzamides have emerged as potent stress inhibitors and growth promoters in plant biotechnology ...

Diastereoselective Synthesis of Highly Substituted Methylene Cyclobutanes by Pd Catalysis

European Journal of Organic Chemistry, Volume 29, Issue 30, 12 August 2026.
A chemo‐ and diastereoselective palladium‐catalyzed intramolecular coupling/cyclization of borylated 1,5‐dienes, readily accessible by allene allylboration, with iodoarenes enables the synthesis of highly substituted methylene cyclobutanes. The method exhibits broad scope, high functional group tolerance, and complete enantiospecificity.

Visible‐Light Photoredox Catalysis in the Intramolecular Dicarbonylation of Alkenes: Catalyst‐Dependent Divergent Syntheses of Both 1,4‐Dicarbonyls and α‐Hydroxy‐β,γ‐Unsaturated Lactams From 1,2‐Dicarbonyls

Advanced Synthesis &Catalysis, Volume 368, Issue 15, 1 August 2026.
Catalyst‐dependent divergent syntheses were developed. Intramolecular dicarbonylation of vinyl halides under metal‐free either thermal or visible light photocatalytic conditions were explored to produce a series of 1,4‐dicarbonyls with two different carbonyl moieties and a lactam ring.

Probing Cinnamamides and Benzamides as Anthelmintics: Discovery of Potent Drug‐Like Agents Against Angiostrongylus cantonensis

Chemical Biology &Drug Design, Volume 108, Issue 1, July 2026.
Cynnamoyl benzylpiperazine was identified as drug‐like derivative of cinnarizine with anthelmintic activity against A. cantonensis. In this work, 15 out of 31 derivatives showed improved anthelmintic activity with increased solubility. A SAR study was carried out to determine the molecular features involved in such effect.

Nickel Photocatalytic Access to β‐Arylated β‐Amino Acids

Advanced Synthesis &Catalysis, Volume 368, Issue 12, 17 June 2026.
Converting naturally abundant amino acids to non‐canonical derivatives in one step under mild conditions allows for improved pharmaceutical properties. Now, this is achieved for β‐arylated β‐amino acids, which are available in good yields directly from aspartic acid, and have the potential to become platform chemicals for drug discovery.
