Synthesis of new biheterocycles containing a 1,4-benzodioxane fragment

The reaction of 1,4-benzodioxane-2-carbonyl chloride with 5-(4-aminophenyl)-1,3,4-oxa- and -thiadiazole-2-thiols afforded new biheterocyclic compounds which were converted into the corresponding S -benzyl derivatives by treatment with benzyl chloride. 5-(4-Aroylaminophenyl)-1,3,4-oxa(thia)diazole-2-...

Zusammenfassung:The reaction of 1,4-benzodioxane-2-carbonyl chloride with 5-(4-aminophenyl)-1,3,4-oxa- and -thiadiazole-2-thiols afforded new biheterocyclic compounds which were converted into the corresponding S -benzyl derivatives by treatment with benzyl chloride. 5-(4-Aroylaminophenyl)-1,3,4-oxa(thia)diazole-2-thiols reacted with 2-bromomethyl-1,4-benzodioxane to give compounds in which the 1,4-benzodioxane nucleus and fivemembered heterocycle are linked through a CH 2 S bridge.
