Thiazolotriazole derivatives have a number of biological activities. Electrophilic intramolecular cyclization unsaturated alkyl 1,2,4-triazole under the action various electrophilic reagents (halogens, tetrahalides chalcogenides) is most effective and simple method synthesis thiazolotriazoles.
 It was previously reported that 3-metalylthio-4,5-diphenyl-1,2,4-triazole reacts with aryltellur...
