Studies in isoxazole chemistry. IV. Isoxazoles via isoxazolines
Canadian Journal of Chemistry, 19704- or 5-Chloro- or cyanoisoxazoles, 5-chloromethylisoxazoles, and 5-methylisoxazoles were made by the 1,3-dipolar cycloaddition of nitrile oxides to α-halogeno- or α-alkoxyolefins. In the case of cis- and trans-1,2-dichloroethylene, (5a and b) the intermediate cis- and trans-4,5-dichloroisoxalines (6a and b) were isolated.

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.

Transformation of 1,2,3,7a-tetrahydroimidazo[1,2-b]isoxazole derivatives into isoxazoles
Russian Chemical Bulletin, 2007The reactions of 1,2,3,7a-tetrahydroimidazo[1,2-b]isoxazole derivatives with electrophilic reagents, such as protic acids, benzoyl chloride, BF3, and bromine, produce isoxazole, 2,2,3,3-tetramethylaziridine, and 2,3,3-trimethylpropen-2-ylamine derivatives.

Isoxazole Ionotropic Glutamate Neurotransmitters
Current Medicinal Chemistry, 2005Analogs of the excitatory neurotransmitter glutamate are potential medicinal agents for a wide variety of neurological disorders. The isoxazole glutamate derivatives represent an important class of compounds because of their receptor specificity and binding affinity. Since the discovery of (S)-2-amino-3-(3-hydroxy-5-methyl-4-isoxazolyl) propionic acid (

Recent Developments in Isoxazole Chemistry
1963Publisher Summary This chapter reviews new investigations in the field of synthetic isoxazoles. Isoxazoles possess the properties of the aromatic system. The syntheses of isoxazole derivatives involving formation of the 1–5 and 2–3 bonds of the isoxazole ring, as well as formation of the 1–5 and 3–4 bonds of the ring are described in the chapter. The
