| Abstract: | Several 1,2,4]triazolobenzothiadiazocin-11-ones 3 were prepared via ring expansion of 1,2,4]triazolo3,2-b]2,4]benzothiazepin-10(5H)-ones 1 in presence of sodium azide. The reaction intermediate was isolated and characterized as an aryl isocyanate 2b . A possible pathway for formation of novel triazolobenzothiadiazocin-11-one 3 is described. |
