- Facile synthesis of 3-aryl/alkylamino 5-aryl/alkyl 1,2,4-oxadiazoles from acylthiourea
-
Facile and selective synthesis of 3-aryl/alkylamino 5-aryl/alkyl 1,2,4-oxadiazoles starting from N-acylthioureas has been demonstrated. The regio-selectivity is achieved by simply selecting an appropriate base used for the generation of hydroxyl amine fro

- PHOTOCHEMICAL BEHAVIOUR OF 1,2,5-OXADIAZOLES - IRRADIATION OF SOME 3-ACYLAMINO-1,2,5-OXADIAZOLES IN THE PRESENCE OF NUCLEOPHILES
-
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.
