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.

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.
