Alkylated, benzylated and bromoalkylated benzimidazole-thione that intramolecularly heterocyclized to 3,4-dihydro-2H-[1,3]thiazino[3,2-a]benzimidazole were synthesized. The chemical structure of the synthesized product was characterized by Infra Red, 1H-NMR, 13C-NMR, and Mass spectroscopy. Furthermore, the molecular structures of 8 and 9 were confirmed by X-ray single crystallography in different space groups, Pbca and P21/c, respectively.
合烷基化、苄基化和溴烷基化的苯并咪唑-硫化物通过分子内杂环化合成了3,4-二氢-2H-[1,3]噻嗪并[3,2-a]苯并咪唑。合成产物的化学结构通过红外光谱、1H-NMR、13C-NMR和质谱进行了表征。此外,化合物8和9的分子结构分别通过X射线单晶衍射在不同的空间群Pbca和P21/c中得到了确认。
