Chemistry of Heterocyclic Compounds Aims and scope

Abstract

The heterocyclization of hydrazides, prepared from methyl 5-phenyl-2-hydrozinothiazole-4-carboxylate and organic acids or their anhydrides, leads to the production of thiazolo[2,3-c]triazoles which do not undergo rearrangement to the corresponding thiazolo[3, 2-b]triazoles under the action of mineral acids. The 2-trifluoroacetylhydrazine derivative does not cyclize, even under severe conditions.
