Synthesis of Enantiopure [3]Cyclorubicenes

Angewandte Chemie, Volume 138, Issue 1, 2 January 2026.
Herein, we present a high yielding synthesis of enantiopure [3]cyclorubicene, which is a potential precursor for a Haeckelite nanotube. This macrocycle was studied for its electronic and chiroptical properties and exhibits one of the highest dissymmetry values reported for a nanohoop.

The continuing significance of chiral agrochemicals

Pest Management Science, Volume 81, Issue 4, Page 1697-1716, April 2025.
In the time frame 2018–2023, around 43% of the 35 chiral agrochemicals introduced to the market (herbicides, fungicides, insecticides, acaricides, and nematicides) contain one or more stereogenic centers in the molecule, and almost 69% of them have been marketed as racemic mixtures of enantiomers or stereoisomers.

Hunting method affects cortisol levels in harvested mountain hares (Lepus timidus)

Wildlife Biology, EarlyView.
The direct effects of hunting on hunted individuals and populations have been well known for a long time. However, recently there has also been an increased focus on the indirect, non‐lethal effects of hunting. When approached by a possible threat such as a predator, the prey releases various stress hormones into the bloodstream.

Uncovering the Key Factors Influencing Phytochemical and Phytopharmacological Properties During Medicinal Plant Processing

eFood, Volume 7, Issue 1, February 2026.
From farm to pharma, this review details the engineering of quality in medicinal plants through a science‐driven approach: it first elucidates how genetic and environmental factors inscribe the plant's phytochemical and phytopharmacological profile before harvest, and then dissects the postharvest techniques and technologies—chemical and thermal pre ...
