2‐Isoxazoline derivatives. Part I. A base‐promoted fragmentation of 2‐isoxazolines

Journal of Heterocyclic Chemistry, 1968
AbstractThe action of bases on 3‐aryl (or alkyl)‐5‐acyl‐2‐isoxazolines has been shown to give rise to the corresponding aromatic (or aliphatic) nitriles and α‐diketones by cleavage of the O‐N and C3C4 bonds of the heterocyclic ring. This fragmentation reaction has been extended to other 2‐isoxazolines substituted in the 5‐position with electron ...

Preparation of Viscosity-Sensitive Isoxazoline/Isoxazolyl-Based Molecular Rotors and Directly Linked BODIPY-Fulleroisoxazoline from the Stable meso-(Nitrile Oxide)-Substituted BODIPY.

Organic Letters, 2019
We developed a simple methodology for the preparation of stable meso-(nitrile oxide)-substituted BODIPYs, which were characterized by spectroscopic methods and X-ray crystallography.

Unusual transformations of 2-isoxazolines

Russian Chemical Reviews, 1997
The data on unusual transformations of 2-isoxazolines observed in both their preparation by traditional methods and various reactions, mostly with nucleophilic reagents, are considered systematically. Possible mechanisms of these reactions are discussed.

Structure and stability of isoxazoline compounds

Russian Journal of General Chemistry, 2013
Structure of isoxazoline compounds formed via the reaction of alkyl-substituted benzonitrile oxides with ethylene was determined by X-ray diffraction method. Isoxazoline ring is flattened, the bond lengths in it depend slightly on the nature of substituents (CH3, C2H5) and their position in the benzene ring and the angle of rotation relative to the ...
