Isoxazoles, benzisoxazoles, isoxazolines, and isoxazolidines are classes of heterocyclic compounds having a remarkable number of applications and are very versatile building blocks in organic synthesis. The major developments on the chemistry of these heterocycles reported in the literature from 1996 to 2006 are reviewed.

Inorganica Chimica Acta, 1975
Abstract A number of divalent 3d metal chloride and perchlorate complexes with isoxazole were obtained by interaction of salt and ligand in triethyl orthoformate-ethanol. Characterization of these complexes was based on spectral (ir--electronic), magnetic and conductance evidence.

Isoxazoles I: Protonation of Isoxazole Derivatives in Aqueous Sulfuric Acid
Journal of Pharmaceutical Sciences, 1973The protonation of 3-amino-5-methylisoxazole, 5-amino-3,4-dimethylisoxazole, sulfamethoxazole (N-sulfanilamido-5-methyl-3-isoxazole), and sulfisoxazole (N-sulfanilamido-3,4-dimethyl-5-isoxazole) in aqueous sulfuric acid was studied. The pKSH+ and log SH+/S or log SH2+2/SH+ values were determined by UV spectrophotometry.

Design, Synthesis and Bioevaluation of Substituted Phenyl Isoxazole Analogs as Herbicide Safeners.
Journal of Agricultural and Food Chemistry, 2020Herbicide safeners enhance herbicide detoxification in crops without affecting target weed sensitivity. To enhance crop tolerance to the toxicity-related stress caused by the herbicide acetochlor (ACT), a new class of substituted phenyl isoxazole ...

Design, Synthesis, and Herbicidal Activity of N-Benzyl-5-cyclopropyl-isoxazole-4-carboxamides.
Journal of Agricultural and Food Chemistry, 2020Based on the structures of isoxaflutole (IFT) and N-isobutyl-N-(4-chloro-benzyl)-4-chloro-2-pentenamide, a series of N-benzyl-5-cyclopropyl-isoxazole-4-carboxamides was designed by connecting their pharmacophores (i.e., a multitarget drug design strategy)
