Rh(III)‐Catalyzed [4+2] Annulation of Imidazoles With α‐Diazocarbonyl Compounds: Direct Access to π‐Conjugated Imidazole‐Fused Isoquinolinone

open access: yesEuropean Journal of Organic Chemistry, Volume 29, Issue 23, 16 June 2026.
A Rh(III)‐catalyzed [4 + 2] annulation of 2‐aryl imidazoles/benzimidazoles with α‐diazocarbonyl compounds is developed for the synthesis of π‐conjugated imidazo/benzimidazo[2,1‐a]isoquinolinones systems. Mechanistic studies and control experiment reveal that the reaction proceeds via imidazole‐directed ortho C(sp2)–H activation, followed by carbene C–H

Optimisation of a Novel Class of DNA Gyrase Inhibitors to Improve Antibacterial Activity

open access: yesChemMedChem, Volume 21, Issue 11, 15 June 2026.
This article describes efforts to increase the antibacterial activity of a recently reported class of novel DNA gyrase inhibitors known as the isoquinoline sulphonamides by improving their uptake in bacterial cells. As antibiotic resistance continues to rise, the need for new antibacterials is clear.
