5-Amino-3-methyl- and 5-amino-3-phenylisothiazoles (3a and 3b) afforded 1:1 adducts with aromatic nitriles and imidates.On the basis of their spectral data and the structure of hydrolysis products, the adducts were identified as 3-substituted 5-(2-aminovinyl)-1,2,4-thiadiazole derivatives (2a-g), where ring transformation took place from isothiazole to 1,2,4-thiadiazole.

3-Acetonyl-1,2,4-oxadiazoles and 2-Acetonyl-1,3,4-oxadiazoles are accessible starting with the ketal of acetoacetamide oxime and the ketal of acetoacetic acid hydrazide, respectively. 5-Acetonyl-1,2,4-thiadiazoles are obtained from 5-chloro-1,2,4-thiadiaz

5-Amino-3-methylisothiazole (3) gave 1:1 adduct with aromatic nitriles and ethyl acetimidate and the structure of the adduct was shown to be 3-substituted 5-(2-amino-2-methylvinyl)-1,2,4-thiadiazole (2) , where ring transformation took place from isothiaz
