Synthetic method of omega-substituted biuret compound

The invention belongs to the field of organic matter synthetic methods, and specifically relates to a synthetic method of an omega-substituted biuret compound. The synthetic method comprises the following steps: (1) condensation: adding substituted arylamine and potassium cyanate into a mixed solution of water and acetonitrile, warming, dropwise adding a part of acetic acid at the temperature of 45 to 100 DEG C, then adding remaining acetic acid 1 h later, and then reacting for 6 to 12 h; and (2) aftertreatment: carrying out recrystallization or column chromatography on an obtained product toobtain the omega-substituted biuret compound. The synthetic method overcomes the disadvantage that a nitrogen nitryl compound with dangerousness needs to be used in an existing synthetic process, anda one-pot method is adopted for replacing an existing two-step reaction with low yield.

Heterocyclic Photorearrangements. Photochemical Behaviour of Some 3,5-Disubstituted 1,2,4-Oxadiazoles in Methanol at 254 nm

Photochemical behaviour of some 3,5-disubstituted 1,2,4-oxadiazoles in methanol at 254 nm has been investigated.Ring photoisomerization to the 1,3,4-oxadiazole heterocycle or formation of open chain compounds involving the nucleophilic solvent was shown to depend on the nature and the position of the substituent.Photoinduced ring closure into the benzimidazole system, involving a 3-N-phenylamino side chain sequence and a photolytic intermediate of the oxadiazole heterocycle, is also reported.
