A mild and efficient method for the synthesis of 3-amino-5-aryl-1,2,4-oxadiazole by intramolecular cyclization using PhI(OAc)2 (PIDA) as an oxidant is developed. Various 3-amino-5-aryl-1,2,4-oxadiazoles are prepared in moderate to good yields,

The thermal rearrangement of N-1,2,4-oxadlazol-3-yl-hydrazones into 1,2,4-triazoie derivatives is reported. This represents the first example of a three-atom side-chain rearrangement involving an NNC sequence linked at the C(3) of the oxadiazole. The reac

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.

The photochemical behaviour of some 1,2,4-oxadiazole derivatives in methanol has been studied at 254 nm.On irradiation, 3-amino- (or 3-methylamino-) 5-aryl-1,2,4-oxadiazoles underwent a ring photoisomerization to 1,3,4-oxadiazoles, probably through a 'rin
