The reactions of 1,2,3,7a-tetrahydroimidazo[1,2-b]isoxazole derivatives with electrophilic reagents, such as protic acids, benzoyl chloride, BF 3, and bromine, produce isoxazole, 2,2,3,3-tetramethylaziridine, and 2,3,3-trimethylpropen-2-ylamine

Starting from bulk chemicals, novel isoxazoledicarboxylic acid esters were prepared and converted to the corresponding dicarboxylic acid monoamides in a few reaction steps and in high overall yields. Key intermediates for the cycloaddition step were chlor

Oxidation of primary nitroalkanes by acetic anhydride/sodium acetate has been found to be more complex than previously suspected. Phenylnitromethane, with acetic anhydride/sodium acetate at 60-80°, for example, gives a mixture of benzoic anhydride, triacethylhydroxylamine and acetanilide, through the mixed anhydride {A figure is presented} as a key intermediate. Evidence in support of this latter species has been obtained by carrying out the oxidation in the presence of dimethyl acetylenedicarboxylate as a 1,3-dipolarophile, when 3-phenyl-4,5-dicarbomethoxyisoxazole is formed in 82% yield. A number of other 3-alkyl- and 3-aryl-4,5-dicarbomethoxyisoxazoles have been prepared in a similar manner.
