Design, Synthesis, and Insecticidal and Fungicidal Activities of Quaternary Ammonium Salt Derivatives of a Triazolyphenyl Isoxazoline Insecticide.

Pest Management Science, 2022
BACKGROUND Insect pests seriously decrease the yield and quality of agricultural crops. Resistance to commonly used insecticides is increasingly undermining their effectiveness, and therefore the development of agents with novel modes of action is ...

Isoxazolin-5-one

Journal of the Chemical Society C: Organic, 1971
The reaction paths leading from ethyl propiolate to isoxazolin-5-one (II) and isoxazolin-3-one (III) are discussed and shown to be pH-dependent. The chemical and tautomeric properties of compound (II) are consistent with the known behaviour of its derivatives.

Construction of Cholesterol Oxime Ether Derivatives Containing Isoxazoline/Isoxazole Fragments and Their Agricultural Bioactive Properties/Control Efficiency.

Journal of Agricultural and Food Chemistry, 2021
To explore natural-product-based pesticidal candidates and high value-added application of cholesterol in agriculture, oximinoether derivatives of cholesterol-containing isoxazoline/isoxazole fragments (I-1∼I-16 and II-1∼II-18) were semiprepared by ...

Rational Design and Synthesis of Isoxazoline Derivatives with Low Bee-Toxicity Based on Bee GABA Receptors.

Journal of Agricultural and Food Chemistry
The isoxazoline insecticide, such as fluralaner, exhibits strong insecticidal activity against pests while showing no cross-resistance. However, due to its toxicity to bees, the use of Fluralaner is restricted in veterinary antiparasitic applications ...

Isoxazoline

2005
The first part of the presented work deals with the enantioselective synthesis of isoxazolines. The synthetic approach involves the asymmetrically catalysed 1,3-dipolar cycloaddition of nitrones to acetylenes. Therefore electrondeficient mono- and bifunctionalysed as well as electronrich triplebond systems, in combination with electronrich and ...
