Insecticidal quinoline and isoquinoline isoxazolines

Bioorganic & Medicinal Chemistry Letters, 2014
A series of quinoline and isoquinoline isoxazolines have been designed as pesticides for crop protection. Herein we reported the chemical synthesis, biological activity and structure-activity relationships. The isoquinoline derivative, such as 3i, is discovered as potent new class of isoxazoline insecticide which is competitive with commercial ...

Enantioselective Synthesis of Isoxazolines Enabled by Palladium-Catalyzed Carboetherification of Alkenyl Oximes.

Angewandte Chemie, 2019
Herein we reported a highly efficient Pd/Xiang-Phos catalyzed enantioselective carboetherification of alkenyl oximes with aryl or alkenyl halides, delivering various chiral 3,5-disubstituted and 3,5,5-trisubstituted isoxazolines in good yield with up to ...

Review of extralabel use of isoxazolines for treatment of demodicosis in dogs and cats.

Journal of the American Veterinary Medical Association, 2020
Amitraz is presently the only FDA-approved treatment for demodicosis in dogs in the United States. Amitraz treatment involves a protracted course of administration and risks of severe adverse effects such as sedation, bradycardia, and respiratory ...

Strong deshielding in aromatic isoxazolines

Magnetic Resonance in Chemistry, 2015
AbstractVery strong proton deshielding was found in di/tri‐aromatic isoxazoline regioisomers prepared from acridin‐4‐yl dipolarophiles and stable benzonitrile oxides (BNO). Three alkenes, (acridin‐4‐yl)‐CHCH‐R (R = COOCH3, Ph, and CONH2), reacted with three BNO dipoles (2,4,6‐trimethoxy, 2,4,6‐trimethyl, 2,6‐dichloro) to give pairs of target ...

[2 + 2 + 1] Heteroannulation of Alkenes with Enynyl Benziodoxolones and Silver Nitrite Involving C≡C bond Oxidative Cleavage: Entry to 3-Aryl-Δ2-isoxazolines.

Organic Letters, 2020
A copper-catalyzed [2 + 2 + 1] heteroannulation of alkenes with enynyl benziodoxolones and AgNO2 involving oxidative cleavage of the C≡C bond promoted by cooperative Zn(OTf)2, KOAc, and 4 Å MS for producing 3-aryl Δ2-isoxazolines is reported. Mechanistic

Visible-Light-Mediated Three-Component Strategy for the Synthesis of Isoxazolines and Isoxazoles.

Organic Letters
Isoxazolines and isoxazoles commonly serve as core structures of many therapeutic agents and natural products. However, the metal-free and catalysis-free strategy for the synthesis of these privileged motifs at room temperature remains a challenging task.

Electrocatalytic Isoxazoline–Nanocarbon Metal Complexes

Journal of the American Chemical Society, 2021
We report the synthesis of new carbon-nanomaterial-based metal chelates that enable effective electronic coupling to electrocatalytic transition metals. In particular, multiwalled carbon nanotubes (MWCNTs) and few-layered graphene (FLG) were covalently functionalized by a microwave-assisted cycloaddition with nitrile oxides to form metal-binding ...
