Catalytic Diastereo- and Enantioselective Synthesis of 2-Imidazolinones [PDF]

open access: yesOrganic Letters, 2019
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-

A Trp574-Leu substitution confers resistance to three classes of acetolactate synthase inhibitors in Australian brome grass (Bromus diandrus). [PDF]

open access: yesPest Manag Sci
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]

open access: yesPlant Direct
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 ...

A Target-Site Mutation Confers Cross-Resistance to ALS-Inhibiting Herbicides in Erigeron sumatrensis from Brazil [PDF]

open access: yesPlants, 2022
Cases of weed resistant to herbicides have changed the dynamics of agricultural areas in Brazil, and in recent years, Erigeron species have caused major problems to farmers in the country, mainly in relation to the ineffectiveness of herbicide treatments

Leaching of Imidazolinones in Irrigation Systems in Rice Cultivation: Sprinkling and Flooding [PDF]

open access: yesPlanta Daninha, 2019
: Herbicides of the imidazolinone group have been used in irrigated rice and presented a long persistence in the soil, especially in floodplain areas with a low drainage, and could cause environmental contamination.

Push It to the Limit: Identification of Novel Amino Acid Changes on the Acetolactate Synthase Enzyme of Rice That Putatively Confer High Level of Tolerance to Different Imidazolinones [PDF]

open access: yesFrontiers in Bioengineering and Biotechnology, 2020
Advancements in genetically modified herbicide tolerance technology opened a new way to manage weed populations in crop fields. Since then, many important genetically modified crops that are tolerant to various herbicides have been developed and ...

Endocrine Disruptive Effects of the Herbicides Linuron, Chloridazon and Metribuzin on Bovine Granulosa Cells. [PDF]

open access: yesReprod Domest Anim
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.

Formation of the Imidazolinone Ring Under Mild Conditions in the Presence of Sodium Hydride

open access: yesMolecules, 2004
Substituted imidazolinones containing heterocyclic carboxylic acids as substituents and possessing herbicidal properties were synthesized by cyclization of 2-amino-2,3-dimethylbutyramide with heterocyclic ethyl dicarboxylates under mild conditions.
