Catalytic Diastereo- and Enantioselective Synthesis of 2-Imidazolinones [PDF]
Chiral cyclic ureas (2-imidazolinones) were prepared by the reaction of nitrones and isocyanoacetate esters using a multicatalytic system that combines a bifunctional Brønsted base-squaramide organocatalyst and Ag+ as a Lewis acid. The reaction could be achieved with a range of nitrones derived from aryl- and cycloalkylaldehydes with moderate diastereo-

The imidazolinones, a new chemical class of herbicides, were shown to be uncompetitive inhibitors of acetohydroxyacid synthase from corn. This is the first common enzyme in the biosynthetic pathway for valine, leucine, and isoleucine. The K(i) for the imidazolinones tested ranged from 2 to 12 micromolar.

A Trp574-Leu substitution confers resistance to three classes of acetolactate synthase inhibitors in Australian brome grass (Bromus diandrus). [PDF]
Target‐site based imidazolinone resistance in brome grass was found to be conferred by a mutation at position 574 in the ALS gene and to severely impact the efficacy of the herbicide Intervix®, a co‐formulation of imazamox and imazapyr. Abstract BACKGROUND Brome grass (Bromus diandrus) is a prevalent weed in southern Australian cropping regions which ...

Subgenomic Distribution and Herbicide Cross-Resistance of <i>ALS</i> Gene Mutations in Allohexaploid <i>Echinochloa crus-galli</i>. [PDF]
ABSTRACT Herbicide target site resistance in polyploid species is more complex than in diploids due to potential subgenome interactions. This study characterized mutations in the ALS gene across distinct subgenomes of hexaploid Echinochloa crus‐galli and evaluated the cross‐resistance patterns conferred by each mutation to various ALS‐inhibiting ...

Endocrine Disruptive Effects of the Herbicides Linuron, Chloridazon and Metribuzin on Bovine Granulosa Cells. [PDF]
ABSTRACT Linuron, chloridazon and metribuzin are herbicides thought to have potential endocrine disruption (ED) effects. This study investigated the effects of linuron, chloridazon and metribuzin on bovine granulosa cell viability and oestrogen (E2) and progesterone (P4) secretion in vitro.

Tolerance to Imidazolinone Herbicides in Wheat [PDF]
An imidazolinone-tolerant wheat (Triticum aestivum L. em Thell) mutant in the winter wheat cultivar Fidel has been identified and characterized. The mutant was isolated from a population derived through seed mutagenesis of the variety with an aqueous solution containing sodium azide.
