method for the synthesis of hydrazine derivatives of fused pyridinethiones based on alicyclic and heterocyclic ketones has been developed. Successive heterocyclization of these hydrazine derivatives was carried out in order to obtain new derivatives of tricyclic triazolo[4,3-a]pyridines, tetracyclic thieno[3,2-e][1,2,4]triazolo[4,3-a]pyridines, as well as a new heterocyclic system of thieno[2,3-c][1,2
开发了一种基于脂环酮和杂环酮的稠合吡啶硫酮肼衍生物的合成方法。对这些肼衍生物进行连续杂环化以获得三环三唑并[4,3- a ]吡啶、四环噻吩并[3,2 -e ][1,2,4]三唑并[ 4,3- a ]的新衍生物]吡啶,以及噻吩并[2,3 - c ][1,2,4]三唑并[3,4- a ]-2,7-萘啶的新杂环体系。
