Quizalofop-p-ethyl Chemical Properties,Uses,Production

Uses

Post-emergence herbicide for control of grassy weeds in broad-leaved crops. Herbicide.

Definition

ChEBI: Quizalofop-P-ethyl is an ethyl 2-{4-[(6-chloroquinoxalin-2-yl)oxy]phenoxy}propanoate that has R configuration. A proherbicide for quizalofop-P, it is used to control annual and perennial grass weeds in a variety of crops, including potatoes, sugar beet, peanuts, cotton and flax. It has a role as a proherbicide and an agrochemical. It is an ethyl 2-{4-[(6-chloroquinoxalin-2-yl)oxy]phenoxy}propanoate and a quinoxaline herbicide. It is functionally related to a quizalofop-P. It is an enantiomer of a (S)-quizalofop-ethyl.

Production Methods

Quizalofop-P-ethyl is commercially produced through a chiral synthesis starting with the etherification of 2,6-dichloroquinoxaline with hydroquinone under basic conditions to form 2-(6-chloroquinoxalin-2-yloxy)phenol, followed by stereoselective alkylation with ethyl (S)-2-bromopropionate (or resolution of the racemic ester via enzymatic or chiral crystallization methods) in the presence of potassium carbonate to yield the active compound.

Mechanism of action

Selective. Acetyl CoA carboxylase inhibitor (ACCase) - distrupts fatty acid biosynthesis and lipid formation.

Purification Methods

This (±)-herbicide forms white crystals from Me2CO/EtOH and sublimes in vacuo. Large quantities can be distilled at high vacuum. Its solubilities at 20o in g/10mL are 0.09 (EtOH), 1.1 (Me2CO), 1.2 (xylene), 2.9 (*C6H6), and is nearly insoluble in H2O (0.3mg/L). The (±)-acid has [95977-28-9]. The R-ester enantiomer has m 76-77o (pale brown crystals from EtOH), [ ] D 20 + 3 5 . 9o (EtOH). It is the more active fatty acid synthase inhibitor (designated DPX-Y6202) used to control grassy weeds in broadleaf crops.
