This article describes the synthesis of 3,4-disubstituted-6,7-dihydro-imidazo[2,1-b][1,3]thiazoles and 3,4-disubstituted-7,8-dihydro-6H-imidazo[2,1-b][1,3]thiazines, having substituted or nonsubstituted phenyl rings at the 5,6 and 2,3 positions, respectively, their cytotoxic effects through noncancer (F2408) and cancer (5RP7) cells, and their detailed 1H- and 13C-nuclear magnetic resonance (NMR) spectral
本文介绍了3,4-二取代-6,7-二氢咪唑并[2,1-b] [1,3]噻唑和3,4-二取代-7,8-二氢-6H-咪唑并[2]的合成,1-b] [1,3]噻嗪类化合物,分别在5,6和2,3位具有取代或未取代的苯环,它们通过非癌细胞(F2408)和癌细胞(5RP7)的细胞毒性作用,及其详细信息1 H和13 C核磁共振(NMR)光谱表征。在碳酸钾(K 2 CO 3)存在下,通过将4,5-二芳基-咪唑-2-硫酮和二卤代烷烃(即1,2-二卤代乙烷或1,3-二卤代丙烷)环化获得标题化合物。在 N,N -二甲基甲酰胺(DMF)。4,5-二芳基-咪唑-2-硫酮是通过将α-羟基酮(酰基辅酶)缩合而制得的,而α-羟基酮是通过将氰化物用醛处理醛与硫脲在AcOH中缩合而制得的。咪唑并[2,1-b] [1,3]噻唑和咪唑并[2,1-b] [1,3]噻嗪衍生物的结构已通过红外(IR),1 H-NMR和13 C-确证。
