Flavin Catalysts in Organic Synthesis

open access: yesAngewandte Chemie, Volume 138, Issue 42, 12 October 2026.
Flavins and their congeners are potent catalysts for organic synthesis inspired by enzymatic transformations. In addition to catalysis in the flavin ground state via covalent intermediates, the excited singlet and triplet states unlock applications including photooxidation, photoreduction, and energy transfer via sensitization.

Hydrogenolysis of Aromatic Oxygenates Over Pt/WO3–ZrO2 in a Water/Decane Biphasic System

open access: yesChemSusChem, Volume 19, Issue 19, 14 October 2026.
Combining a water‐tolerant Pt/WO3–ZrO2 catalyst with a water/decane biphasic system enables efficient hydrogenolysis of lignin‐derived aromatic oxygenates under mild conditions. Spatial separation of the catalyst and arene products suppresses over‐hydrogenation, providing high aromatic selectivity at only 90 °C and 0.1 atm H2.

One‐Shot Pd(II)‐Catalyzed Multiple C–H Activation Enables Modular Construction of Fluorenylidene Oxindole‐Based Multi(Polycyclic) Aromatic Enes

open access: yesChemistry – A European Journal, Volume 32, Issue 38, 13 October 2026.
A one‐shot Pd(II)‐catalyzed C─H activation strategy enables the rapid conversion of simple linear propiolamides into structurally diverse mono‐, di‐, and tri‐olefin‐bridged MPAEs. This cascade process orchestrates up to six sequential C–H activations in a single operation, providing streamlined access to highly conjugated architectures.

A Selectfluor‐based Polonovski Rearrangement Leading to Novel Entities for Synthetic and Medicinal Applications

open access: yesChemistry – A European Journal, Volume 32, Issue 38, 13 October 2026.
Starting from carboxylic acids and Selectfluor‐derivatives, functionalized diazabicyclooctanes can be obtained via a novel Polonovski‐type rearrangement proceeding under mild reaction conditions. Besides their use in organic synthesis the unique structure and reactivity of the rearrangement products enables applications in medicinal chemistry ...
