Testing Differently Substituted Quinoxaline‐2,3‐Dithiolate Ligands in Z‐Stereoretentive Olefin Metathesis Leading to Pheromone of Rice Yellow Stem Borer (Scirpophaga incertulas)

open access: yesEuropean Journal of Lipid Science and Technology, EarlyView.
A set of Z‐stereoretentive olefin metathesis catalysts was tested in the synthesis of a pheromone of rice yellow stem borer (Scirpophaga incertulas)—one of the major rice pests in Asia. ABSTRACT Stereoselective olefin metathesis offers access to geometrically well‐defined C–C double bonds and is considered a promising new method for transforming plant ...

Stereoselective Synthesis of Unsymmetrical 3,3‐Diarylpropenals by a Suzuki‐Miyaura Reaction of (Z)‐3‐Aryl‐3‐chloropropenal Intermediates

open access: yesEuropean Journal of Organic Chemistry, Accepted Article.
Using (Z)‐3‐aryl‐3‐chloropropenals, we have developed an efficient route for the stereoselective synthesis of unsymmetrical 3,3‐diarylpropenals in high yield with very good retention of stereochemistry. Consequently, we have found an efficient route for the stereoselective synthesis of 3,3‐diarylpropenoic acids which are precursors to 4‐arylcoumarins ...

Severity of effect considerations regarding the use of mutation as a toxicological endpoint for risk assessment: A report from the 8th International Workshop on Genotoxicity Testing (IWGT)

open access: yesEnvironmental and Molecular Mutagenesis, EarlyView.
Abstract Exposure levels without appreciable human health risk may be determined by dividing a point of departure on a dose–response curve (e.g., benchmark dose) by a composite adjustment factor (AF). An “effect severity” AF (ESAF) is employed in some regulatory contexts.

From waste to resource: Garlic peel‐derived proteases (Allium sativum) for nematode control

open access: yesEnvironmental Progress &Sustainable Energy, EarlyView.
Abstract This study aimed to prepare a protease‐rich extract from garlic peel (Allium sativum) and evaluate its nematicidal potential. The garlic peel was crushed, suspended in distilled water, and the obtained extract was subjected to filtration, centrifugation, and dialysis to concentrate the proteases. The nematicidal activity was tested in vitro on
