Anti‐Lipogenic Effects of Iridoid‐Rich Lonicera caerulea Berry Extracts in a Cortisol‐Stimulated Adipocyte Model

open access: yesJournal of Food Science, Volume 91, Issue 4, April 2026.
ABSTRACT Berries of Lonicera caerulea (blue honeysuckle; haskap) have been used since ancient times in traditional medicine in China, Japan, and northern Russia. This study aimed to extract, characterize, and evaluate the biological activity of iridoid‐rich fractions from haskap berries using an in vitro adipocyte model.

Synthetic Studies on Cyclopentane Derivatives

open access: yesAgricultural and Biological Chemistry, 1969
An alternative route to dl-prostaglandin-B1 using the Grignard reaction of 2-(6′-tert-butyloxycarbonylhexyl)-3-methoxy-2-cyclopenten-1-one(XII) with 3-tetrahydropyranyloxy-1-octyne was developed.An easy synthesis of dihydrojasmone was also described.

Dynamic Covalent Polymeric Foams: En Route to a Sustainable Lightness

open access: yesChemSusChem, Volume 19, Issue 5, 13 March 2026.
Dynamic covalent polymer foams (DCPFs) combine lightweight cellular structures with adaptive polymer networks, enabling self‐healing, reprocessability, and recyclability. By integrating reversible covalent bonds into foam architectures, these materials open new pathways toward sustainable porous polymers within a circular materials economy.

Light‐Induced Reactions of Small‐Membered Cyclic Carbonyl Compounds

open access: yesEuropean Journal of Organic Chemistry, Volume 29, Issue 10, 9 March 2026.
This review highlights recent advances in the synthesis and photochemical reactivity of cyclopropenone and cyclobutenedione. These compounds undergo photolysis upon direct excitation, and in some cases, through indirect excitation by photocatalysts. The resulting photogenerated species exhibit unique reactivity profiles that are strongly influenced by ...

Radical Retrosynthesis of Natural Products Enabled by Iron‐Based Reductive Olefin Coupling

open access: yesAngewandte Chemie Novit, Volume 2, Issue 1, March 2026.
This review highlights iron‐catalyzed reductive olefin coupling (ROC)—a strategy for C─C bond formation driven by metal‐hydride hydrogen atom transfer (MHAT)—as a key tool in natural products synthesis. This review surveys dozens of total syntheses employing ROC‐based strategies, highlighting its power to forge strained rings, quaternary centers, and ...
