Bicyclic Isoxazoline Derivatives: Synthesis and Evaluation of Biological Activity
The application of non-planar scaffolds in drug design allows for the enlargement of the chemical space, and for the construction of molecules that have more effective target–ligand interactions or are less prone to the development of resistance.

A one-pot synthesis of 3-trifluoromethyl-2-isoxazolines from trifluoromethyl aldoxime
Functionalized 3-trifluoromethyl-2-isoxazolines and 3-trifluoromethylisoxazoles were easily prepared from trifluoromethyl aldoxime 2 under mild conditions by using DIB as oxidant.

Aryl acetaldoximes are reacted with allylarenes in the presence of sodium hypochlorite to give 3,5-bis(arylmethyl)-2-isoxazolines which are then converted to 1,5-diaryl-4-hydroxy-2-pentanones by a reductive hydrogenation in the presence of water.

Synthesis and antibacterial studies of some novel isoxazoline derivatives [PDF]
A series of 3-[3-(2,4-dichloro-5-fluorophenyl)-5-(2-furyl)-4,5-dihydro-1H-pyrazol-1-yl]-5-(substituted phenyl/2-thienyl)isoxazolines (4a-j) were prepared. The structures of the isoxazoline derivatives were confirmed on the bases of elemental analysis and

One Step Regioselective Synthesis of 5-Aminoisoxazoles from Nitrile Oxides and α-Cyanoenamines
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
