Mechanochemical Generation of Active Pd/BippyPhos Catalyst for Efficient CN Cross‐Coupling in Air

open access: yesChemSusChem, EarlyView.
A solvent‐free, solid‐state Buchwald–Hartwig amination is developed using [Pd(π‐cinnamyl)Cl]2 and bulky electron‐rich phosphines. The active catalyst forms without solvent or inert atmosphere, as confirmed by solid‐state 31P nuclear magnetic resonance.

Chiral Materials from Biomass: 3‐deoxy‐α‐D‐ribono‐1,4‐lactone and 3‐deoxy‐α‐D‐arabino‐1,4‐lactone via the Bromination of Cyrene

open access: yesEuropean Journal of Organic Chemistry, Volume 28, Issue 19, May 27, 2025.
The biomass pyrolysis product levoglucosenone enables the preparation of the feeding modulator 3‐deoxy‐d‐arabino‐1,4‐lactone and the diastereomer 3‐deoxy‐d‐ribono‐1,4‐lactone. The key steps involve a diastereoselective bromination using an enamine bromination‐hydrolysis strategy on the bicyclic ring‐system followed by selective nucleophilic ...

Benzochalcogenodiazoles, Synthesis, and Applications in Medicinal Chemistry and Photomedicine

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
Benzochalcogenodiazoles (BXD) including benzoxadiazoles, benzothiadiazoles, and benzoselenadiazoles are initially mainly designed for optoelectronic materials as electron‐deficient cores. Nevertheless, they are now extending their application to biology.

Enantioselective Anion‐Binding‐Catalyzed Nucleophilic Addition to 4‐Quinolones

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
The first organocatalytic enantioselective formal 1,4‐addition to 4‐quinolones has been developed. This method relies on chiral triazole‐based anion‐binding catalysis using enol nucleophiles, complementing previous metal catalytic approaches. Moderate to good yields and enantioselectivities were achieved by in situ silylation and formation of a key ...
