The Elements of Chiral Brønsted Acids for Stereoselective Transformations

Asian Journal of Organic Chemistry, Volume 15, Issue 11, November 2026.
This review focuses on chiral Brønsted acids (CBAs), examining how each structural component influences the stereochemical outcome. For each element—scaffold, acidic site, substituents—we identify advantages and disadvantages relevant to the catalyst design and selection.

Biosynthetic Pathways and Regulation of Antibacterial Compounds From Endophytic Fungi: From Chemistry to Genomics and Biotechnology

Chemistry &Biodiversity, Volume 23, Issue 11, November 2026.
Endophytic fungi encode abundant cryptic biosynthetic gene clusters that remain largely silent under conventional cultivation. This review highlights how genome mining, multi‐omics, and cluster activation strategies bridge the BGC‐to‐metabolite gap, enabling the discovery of structurally diverse antibacterial natural products with activity against ...

Seabird Prey in Space and Time: Combining Multiple Datasets to Model the Distribution of Sandeel (Ammodytes marinus) and Sprat (Sprattus sprattus) in the North Sea

Ecology and Evolution, Volume 16, Issue 11, November 2026.
Forage fish are key prey and commercial species in the North Sea ecosystem, but estimates of their biomass over detailed spatial and temporal scales is currently limited. To fill this vital research gap we employ Hierarchical Bayesian spatiotemporal models of sandeel (Ammodytes marinus) and sprat (Sprattus sprattus) in the North Sea, providing fine ...

UHPLC‐DAD‐HRMS2 Characterization of Novel Dihydrochalcone Conjugates From the Antiviral Mansoa hirsuta Extracts: Diagnostic Fragmentation Pathways and Dereplication of Oligomeric Polyphenols

Journal of Mass Spectrometry, Volume 61, Issue 11, November 2026.
ABSTRACT High‐resolution mass spectrometry (HRMS) coupled with ultra‐high‐performance liquid chromatography (UHPLC) enables rapid characterization of complex polyphenolic constituents in medicinal plants. Mansoa hirsuta (Bignoniaceae), a neotropical liana traditionally used to treat infectious diseases, remains poorly characterized chemically.

Effect of Solvent Polarity on the Anionic Polymerization of (Z)‐1‐Phenyl[3]Dendralene

Macromolecular Chemistry and Physics, Volume 227, Issue 21, 13 November 2026.
Anionic polymerization of (Z)‐1‐phenyl[3]dendralene in toluene afforded a polymer with the expected molecular weight and a narrow molecular weight distribution under appropriate polymerization conditions. However, broadening of the molecular weight distribution and gelation of the polymerization product occur when the polymerization mixture is allowed ...
