SYNTHESE DES PYRAZOLO[2,3‐a]TRIAZEPINO[3,2‐a]BENZIMIDAZOLES ET DES PYRAZOLO[3,2‐d][1,3,5]THIADIAZEPINO[3,2‐a]BENZIMIDAZOLES A PARTIR DES 1,5‐BENZODIAZEPINES

1,5-benzodiazepine-2-thiones were used as precursors in the synthesis of new heterocyclic systems: pyrazolo-[2,3-a][1,3,5]triazepino[3,2-a]benzimidazoles and pyrazolo[3,2-d][1,3,5]thiadiazepino[3,2-a]benzimidazoles.
