Triheterocyclic thiadiazepine derivatives of pharmacological interest:synthesis of 2-aryl-4-p-(2,3-dihydro-5-methyl-2-oxo-1,3,4-oxadiazol-3-yl)phenyl-6-(un)substituent-1′′,2′′,4′′-triazolo3′′,4′′-b-1′,3′,4′-thiadiazepine

Abstract Synthesis of novel thiadiazepine derivatives based on the reactivity of 4-acetylphenylsydnone (1) was reported. The structures of the newly synthesized compounds have been proved by their physical, analytical, IR, 1H NMR, 13C NMR and mass spectral data
