A new series of N-[3-(10H-phenothiazinyl)-propyl]-2-(substituted
phenyl)-4-oxo-5-( substituted benzylidene)-1,3-thiazolidine-carboxamide,
5(as) have been synthesized. The cycloaddition reaction of thioglycolic acid
with N-[3-(10H-phenothiazinyl)-propyl]-N?-[(substituted phenyl)-methylidene]-
urea, 3(a-s) in the presence of anhydrous ZnCl2 afforded new heterocyclic
compounds N-[3-(10H-phenothiazinyl)-propyl]-2-(substituted phenyl)-4-oxo-
1,3-thiazolidine-carboxamide, 4(a-s). The later product on treatment with
several selected substituted aromatic aldehydes in the presence of C2H5ONa
undergoes Knoevenagel reaction to yield 5(a-s). The structure of compounds 1,
2, 3(a-s), 4(a-s) and 5(a-s) were confirmed by IR, 1H NMR, 13C NMR, Fmass
and chemical analysis. All above compounds were screened for their
antimicrobial activity against some selected bacteria and fungi and for
antituberculosis activity compounds have been screened against the bacterium
M. tuberculosis.
新系列的 N-[3-(10H-吩噻嗪基)-丙基]-2-(取代的
苯基)-4-氧代-5-(取代的亚苄基)-1,3-噻唑烷甲酰胺、
5(as)的合成。硫代乙醇酸与 N-[3-(10-苯基)
与 N-[3-(10H-吩噻嗪基)-丙基]-N?
脲,3(a-s) 在无水氯化锌存在下生成新的杂环
化合物 N-[3-(10H-吩噻嗪基)-丙基]-2-(取代苯基)-4-氧代-1,3-噻唑烷,3(a-s)
1,3-噻唑烷甲酰胺,4(a-s)。后一种产物在与
在 C2H5ONa 的存在下,与几种选定的取代芳香醛处理后的产物
发生 Knoevenagel 反应,生成 5(a-s)。化合物 1、
2、3(a-s)、4(a-s) 和 5(a-s)的结构通过红外光谱、1H NMR、13C NMR、Fmass
和化学分析进行了确认。对上述所有化合物进行了
对一些特定细菌和真菌的抗菌活性,以及
对结核杆菌的抗结核活性也进行了筛选。
