Mechanistic Dichotomy in Enantioselective Pd‐Catalyzed Alkylation of Pyrroles With Diazoesters

European Journal of Organic Chemistry, Volume 29, Issue 33, 1 September 2026.
Ligand‐controlled mechanistic divergence controls the Pd‐catalyzed asymmetric alkylation of pyrroles with diazoesters. While bipyridine ligands promote a conventional metal‐carbene pathway, bipyridine‐N,N′‐dioxide ligands redirect catalysis through electrophilic CH metalation before carbene transfer.

Stereoselective and Diastereospecific Aminosilylation and Hydrosilylation of Heterobicyclic Alkenes by Copper Catalysis Under Mild Conditions

European Journal of Organic Chemistry, Volume 29, Issue 33, 1 September 2026.
An efficient and straightforward methodology for the stereoselective and diastereospecific aminosilylation and hydrosilylation of heterobicyclic norbornene derivatives is introduced. The mild conditions enable the functionalization of norbornene substrates with broad functional‐group tolerance.

Nomenclature Survey of the Genus Amaranthus (Amaranthaceae). 13. The Identity of Amaranthus tortuosus

Feddes Repertorium, Volume 137, Issue 3, September 2026.
ABSTRACT The name Amaranthus tortuosus, a species described by Hornemann in 1819, is currently treated in different ways, either as an accepted name, as a synonym of A. dubius or A. hybridus s.str., or as an unplaced name. In order to clarify its application, we reassessed its taxonomic identity within the genus Amaranthus.

Engaging the public in plant science: Communication facilitators and barriers of scaling up a citizen science campaign

People and Nature, Volume 8, Issue 9, Page 2925-2940, September 2026.
Abstract Volunteers have been involved in nature observations for decades through citizen science initiatives, providing large data sets as well as problem identification that allow a more complete understanding of many natural phenomena. Although communication is a core component in citizen science, the key factors that determine its effectiveness in ...

Ethnobotanical insights into the medicinal and food uses of Lamiaceae in the Mediterranean region: A systematic review and meta‐analysis

PLANTS, PEOPLE, PLANET, Volume 8, Issue 5, Page 1500-1516, September 2026.
For generations, Mediterranean communities have used Lamiaceae or Labiatae plants like rosemary, thyme or mint to care for their health and to enrich their food. By bringing together dispersed knowledge from across the Mediterranean region, our review revealed the continuing relevance of Lamiaceae while also compiling past uses that may hold future ...
