Inter- and intramolecular heterocyclisation carbonyl compounds and them thiacarbam derivatives an alicyclic structure depending of activation of nucleophilic centers it is carried out regiodirectly with formation of unknown earlier annelic and spitoycitic compounds thiazolic and thiadiazolic lines, perspective by way of studying biological activity.
Given the ability of 1,5-dicarbonyl compounds to emerge in the presence of ammonia, urea and its derivatives of N-containing heterocyclic compounds, possibility of сyclization 2-pentene- and pentane-1,5-diones and their dihalogensubstituted analogues with thioacetamide.
