A Solvent‐Free Synthesis of Imidazo[1,5‐a]pyridines Using CCl4 as an Oxidant
Journal of Heterocyclic Chemistry, EarlyView.A solvent‐free synthesis of imidazo[1,5‐a]pyridines (Impys) using CCl4 as an oxidant reagent and DBU as the base is informed. An array of Impys derived from different benzylic, heteroaryl aldehydes and others was synthesized in moderate to good yields.

Quarterly Journal of the Royal Meteorological Society, EarlyView.We document the protocol and first results from the first ever coordinated multimodel variable‐resolution experiment set with refinement over the polar regions. We find that the refinement generally yields model‐dependent effects. The most consistent improvement is an amelioration of the upper‐level cold bias in the polar regions that translates into ...

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.The chelating imino groups in [MCl4(DADDTEthane)] (M = Ti, Zr, Hf) give rise to a planar five‐membered (‐N=C‐C=N‐)M metallacycle. The two thiophene rings of the ligand backbone reside in a noncoplanar arrangement concerning the metallacycle, giving rise to two chiral C–C axes in the ligand backbone.

British Journal of Pharmacology, EarlyView.Background and Purpose Metabolic dysfunction‐associated steatohepatitis (MASH) is linked to activation of hepatic stellate cells (HSCs) to α‐smooth muscle actin–positive myofibroblasts that produce collagen and proinflammatory cytokines. Quiescent HSCs express the NO‐cGMP signalling axis.

A Negatively Curved Pyrene‐Fused Azaacene
Angewandte Chemie, Volume 138, Issue 24, 8 June 2026.A pyrene‐fused azaacene derivative is reported in which steric overcrowding caused by eight phenyl substituents induces bending of the aromatic framework rather than twisting. ABSTRACT Non‐planar aromatic hydrocarbons display distorted π‐frameworks that give rise to unique optoelectronic properties.
