A generalized and efficient synthesis of 3-amino-, 3-(N-alkylamino)-, 3-(N,N-dialkylamino)-5-alkyl-1,2,4-oxadiazoles by irradiation of 3-alkanoylamino-4-phenyl-1,2,5-oxadiazoles (Furazans)

Irradiation of 3-alkanoylamino-4-phenyl-1,2,5-oxadiazoles (furazans) at λ = 310 nm in methanol and in the presence of ammonia, primary or secondary aliphatic amines produced excellent yields of 3-amino-, 3-(N-alkylamino)-, 3-(N,N-dialkylamino)-5-alkyl-1,2
