Acyclic nitronate olefin cycloaddition (ANOC): regio- and stereospecific synthesis of isoxazolines
Chemical Science, 2020 We report the first demonstrations of intra- and intermolecular acyclic nitronate olefin cycloaddition (ANOC) reactions that enable the highly efficient syntheses of isoxazolines bearing various functional groups.

A comparative laboratory trial evaluating the immediate efficacy of fluralaner, afoxolaner, sarolaner and imidacloprid + permethrin against adult Rhipicephalus sanguineus (sensu lato) ticks attached to dogs [PDF]
, 2012 Variational methods are used for targeting specific correlation effects by tailoring the configuration space. Independent sets of correlation orbitals, embedded in partitioned correlation functions (PCFs), are produced from multiconfiguration Hartree-

One Step Regioselective Synthesis of 5-Aminoisoxazoles from Nitrile Oxides and α-Cyanoenamines
Molecules, 2004 The 1,3-dipolar cycloaddition of nitrile oxides to 1-cyanoenamines gives 5-aminoisoxazoles regioselectively. Moderate to good yields could be obtained depending on the method used to generate the nitrile oxides. The intermediate isoxazolines could not be

Crystal structure of 5-(4-tert-butoxyphenyl)-3-(4-n-octyloxyphenyl)-4,5-dihydroisoxazole
Acta Crystallographica Section E: Crystallographic Communications, 2019 The molecule of the title compound, C27H37NO3, was prepared by [3 + 2] 1,3-dipolar cycloaddition of 4-n-octylphenylnitrile oxide and 4-tert-butoxystyrene, the latter compound being a very useful intermediate to the synthesis of liquid-crystalline ...

An anomalous hydration/dehydration sequence for the mild generation of a nitrile oxide [PDF]
, 2011 A nitrile oxide containing a carbamoyl group is readily generated upon the treatment of 2-methyl-4-nitro-3-isoxazolin-5(2H)-one with water under mild reaction conditions, even in the absence of special reagents.

Efficacy of fluralaner against canine generalized demodicosis
Brazilian Journal of Veterinary Medicine, 2019 Demodicosis is a parasitic dermatopathy, resulting from the excessive proliferation of Demodex mites. The rate at which this disease is encountered in the pet clinic is high, despite recent advances in the treatment of the disease. The aim of this study,
