Taxonomy and diversity of Marcgraviaceae, north of the São Francisco river, northeast Brazil

open access: yesNordic Journal of Botany, Volume 2026, Issue 4, April 2026.
This study provides a comprehensive assessment of Marcgraviaceae species diversity north of the São Francisco river in northeastern Brazil, analyzing species richness and distribution patterns across 384 000 km² of phytogeographic domains. Through field collections, herbarium studies (both physical and digital), and detailed morphological analyses, we ...

A Convenient Laboratory‐Scale Synthesis Route Toward the PPARα Agonist Pemafibrate

open access: yesChemistryOpen, Volume 15, Issue 4, April 2026.
Pemafibrate is a potent peroxisome proliferator‐activated receptor alpha (PPARα) agonist that is widely used in metabolic disease research. An optimized, practical, and high‐yielding synthetic route toward pemafibrate in excellent optical purity is reported. This multigram‐scale approach overcomes limitations associated with previously reported methods

Streamlined One‐Pot Synthesis of Fused Pyrroles: A Three‐Component Approach

open access: yesChemistryOpen, Volume 15, Issue 4, April 2026.
New modified pyrrole derivatives, namely tetrahydroindol‐4‐ones and pyrrolo[2,3‐d]pyrimidines, functionalized at position 3, were synthesized through a one‐pot multicomponent condensation. Stabilized dimedone enaminones derived from α‐amino acids and their esters (or 6‐amino‐1,3‐dimethyluracil), arylglyoxals, and methylene‐active compounds ...
