Study of direction of cyclization of 1-azolil-4-aryl/alkyl- thiosemicarbazides

On a four series of 1-azolil-4-aryl/alkyl-thiosemicabazides, a study on the influence of azole moiety on the capability for intramolecular cyclization and its direction was carried out. It was found that for 4-aryl/alkyl- thiosemicabazides with triazole, imidazole, or pyrrole moiety at N-1 nitrogen atom possible products were only s-triazoles, both in alkaline and acidic medium. Successful dehydrocyclization of 1-azolil-4-aryl/alkyl- thiosemicarbazides leading to a thiadiazole has been documented only for a series of 1-(4-methyl-1,2,3-thiadiazol-5-yl-carbonyl)-4-aryl/alkyl- thiosemicarbazides. It can be speculative that the determination of pK a value of oxygen atom of 1-azolil-4-aryl/alkyl-thiosemicarbazide can be a very valuable parameter in the prediction of the possibility of dehydrocyclization to form thiadiazole.
