An atlas of plant selenium metabolism

open access: yesNew Phytologist, Volume 250, Issue 4, Page 2041-2060, May 2026.
Summary Selenium (Se) is not only a rare and toxic element but also an essential micronutrient for humans and animals that is often in short supply. Terrestrial plants do not require Se, but it can have growth‐promoting or negative effects, depending on the exposure level.

Synthesis of Sulfur Heterocycles by Palladium‐Catalyzed Cyclization

open access: yesEuropean Journal of Organic Chemistry, Volume 29, Issue 14, 15 April 2026.
In spite of the well‐known palladium thiophilicity, sulfur‐containing acyclic substrates may efficiently undergo several different kinds of palladium‐catalyzed cyclization processes leading to highly important sulfur heterocycles in one synthetic step. Advances in this challenging and stimulating field of research are presented in this review.

Thermodynamic Functions of Thiazole and iso-Thiazole

open access: yesCroatica Chemica Acta, 1967
Some thermodynamic functions (the enthalpy and free energy functi ons, entropy and heat capacity) of thiazole and iso-thiazole have been calculated (300-1000° K), using the harmonic-oscillator, rigid-rotor approximation. The reported assignments for the two molecules were us ed, as were the published values for the moments of inertia of thiazole ...

Modulating IDO1 and TDO Inhibition Through Structural Modification of Diaryl Hydroxylamines

open access: yesChemMedChem, Volume 21, Issue 7, 14 April 2026.
Diaryl hydroxylamines have emerged as promising scaffolds for targeting the tryptophan‐catabolizing enzymes indoleamine 2,3‐dioxygenase 1 (IDO1) and tryptophan 2,3‐dioxygenase (TDO), key drivers of tumor immune escape. Building on the reported dual IDO1/TDO inhibitory activity of O‐((3,5‐difluorophenyl)(phenyl)methyl)hydroxylamine, a series of diaryl ...

Heteroaryl‐Substituted Polyfluorobiaryls Synthesis via Palladium‐Catalyzed Double C─H Bond Functionalization Using Palladium 1,4‐Migration Associated to Direct Arylation

open access: yesEuropean Journal of Organic Chemistry, Volume 29, Issue 13, 13 April 2026.
Fluoro substituents on a benzene ring linked to a 2‐bromoaryl group enables the selective activation of one of its C─H bonds via Pd‐1,4‐migration. Then, Pd‐catalyzed direct coupling with heteroarenes produces C2’‐heteroarylated 1,1′‐biaryls. In this reaction, the new C–C bond arises from the functionalization of two C─H bonds.
