Abstract
The reaction of 1-alkyl-2-chloro-1H-indole-3-carbaldehydes with 4-amino-5-alkyl(aryl)-4H-1,2,4-triazole-3-thiols afforded new heterocyclic compounds, namely triazolo(thiadiazepino)indoles. Structure of the latter was established by single crystal X-ray diffraction method. This heterocyclic system is formed upon cyclization of the intermediate 5-alkyl-4-[indol-3-yl(methylideneamino)]-4H-1,2,4-triazole-3-thiols.
