Gold(I)‐Mediated Reactivity of Allenes With Mesoionic Nucleophiles: A Computational Exploration

European Journal of Organic Chemistry, Volume 29, Issue 24, 23 June 2026.
The regioselective gold(I)‐mediated reactivity of allenes with mesoionic nucleophiles has been evaluated through computational analysis of the mechanisms involved. Instead of typical (3 + 2) pathways, sydnones and münchnones favour the formal (3 + 3) cyclizations affording substituted dihydropyridines.

Lithium Diisopropylamide‐Mediated Ring‐Opening of Tetrahydrofuran in the Synthesis of Polyhydroxylated Indolizidines

European Journal of Organic Chemistry, Volume 29, Issue 24, 23 June 2026.
Chiral tri‐ and pentahydroxy spirocyclopentane‐indolizidines were synthesized using lithium diisopropylamide “LDA” promoted diallylation and tetrahydrofuran “THF” ring‐opening in a one‐pot procedure as a key step. The sequence leading to the targeted hydroxy‐spiroindolizidines was achieved by cis‐dihydroxylation followed by reduction of the enamine and

Aziridination of a Single Carbon Atom in Alkenes via Energy Transfer Catalysis

Angewandte Chemie International Edition, Volume 65, Issue 26, 22 June 2026.
Contrary to traditional alkene aziridination via (formal) nitrene transfer, we herein report a strategy that achieves intermolecular aziridination of a single alkene carbon atom and installs an additional group at the other. Enabled by metal‐free energy transfer (EnT) catalysis, alkenyl boronates and silanes are transformed into reactive intermediates ...

Mild N‑Arylation of Sulfoximines With (Hetero)aryl Chlorides Enabled by α‐Methylnaphthyl‐tBuBrettPhos Palladium Triflate

Chemistry – A European Journal, Volume 32, Issue 23, 16 June 2026.
A readily accessible, air‐ and moisture‐stable palladium precatalyst, [Pd(1‐MeNAP)(tBuBrettPhos)]OTf, enables the direct N‐arylation of NH‐sulfoximines with (hetero)aryl chlorides under exceptionally mild conditions ideal for late‐stage diversification of drug‐like scaffolds.

Merging Biocatalysis and Chemocatalysis in Flow: State‐of‐the‐Art and Future Directions for Sustainable Synthesis

Angewandte Chemie, Volume 138, Issue 25, 15 June 2026.
This review highlights recent advances in integrating biocatalysis and chemocatalysis in continuous flow to create streamlined, sustainable processes. It examines chemo‐enzymatic cascades combining at least one enzymatic and one chemical step, discusses challenges such as enzyme immobilization, leaching, and reactor clogging, and presents solutions ...
