Abstract:

The transformation of 1,2,3-thiadiazolyl hydrazones of aldehydes and ketones including Dimroth rearrangement giving 1-alkylidenamino-5-mercapto-1,2,3-triazoles, alkylation of mercapto group of these heterocyclic compounds by alpha-bromoacetophenones and cyclization giving 6,7-dihydro-5H-{[}1,2,3] triazolo {[}5,1-b]{[}1,3,4] thiadizines have been investigated. It was shown that the reaction for hydrazones of acetophenones and benzoaldehydes is diastereoselective. Triazolothiadiazine spiro derivatives were prepared with transformation of hydrazones of cyclic ketones.
