Synthesis of fused s-triazoles from 2-methanesulfonyl-5-phenyl-1,3,4-oxadiazole and binucleophilic reagents by means of intramolecular ring transformation.
The 4-hydroxyalkyl-1,2,4-triazole-3-thiones cyclization allowed its to work out the effective method of 1,3-thiazacycloalkyl[3,2-b]-1,2,4-triazoles synthesis. Some of the compounds that were obtained were tested for their tuberculostatic activity.
