A generalized synthesis of 3-amino-5-aryl-, 3-amino-5-polyfluorophenyl- and 3-amino-5-alkyl-1,2,4-oxadiazoles has been developed starting from the 3-amino-5-methyl-1,2,4-oxadiazole as a common synthon. Aroylation or alkanoylation of this aminooxadiazole,
PHOTOCHEMICAL BEHAVIOUR OF 1,2,5-OXADIAZOLES - IRRADIATION OF SOME 3-ACYLAMINO-1,2,5-OXADIAZOLES IN THE PRESENCE OF NUCLEOPHILES

, p. 2313 - 2322 (2007/10/02)
The photochemical behaviour of some 3-acylamino-1,2,5-oxadiazoles (furazans) has been investigated.On irradiation at 254 nm in the presence of nucleophiles (ammonia, primary or secondary amines), the photoreaction produced 3-substituted 1,2,3-oxadiazoles in which the substituent at C(3) arises from the used reagent.Some mechanistic considerations are reported.
Heterocyclic Rearrangements: Rearrangement of N-(1,2,4-Oxadiazol-3-yl)-β-enamino Ketones into Pyrimidine N-Oxides

, p. 17 - 20 (2007/10/02)
The behaviour of N-(5-R-1,2,4-oxadiazol-3-yl)-β-enamino ketones towards rearrangement has been investigated.In the presence of anionic reagents in ethanol solution, they rearrange to pyrimidine N-oxides.The synthesis and hydrolytic ring opening of a oxadiazolopyrimidinium system is also reported.
