Regioselective synthesis of novel 4,5-diaryl functionalized 3,4-dihydropyrimidine-2(1H)-thiones via a non-Biginelli-type approach and evaluation of their in vitro anticancer activity
Regioselective synthesis of novel 4,5-diaryl functionalized 3,4-dihydropyrimidine-2(1H)-thiones via a non-Biginelli-type approach and evaluation of their in vitro anticancer activity
Novel pyrimidine derivatives were prepared from the reaction of 2‐substituted 1,3‐bis(dimethylamino)‐trimethinium salts with thiourea or guanidine in the presence of ethyl‐diisopropylamine in ethanol at reflux, and also some 5‐substituted pyrimidine‐2‐thiols has been used for the synthesis of novel disulfane compounds. Infrared, 1H NMR, 13C NMR, and mass spectral data confirm the molecular structures
新型嘧啶衍生物是由2-取代的1,3-双(二甲基氨基)-三甲基亚锡盐与硫脲或胍在乙基二异丙胺存在下于乙醇中回流反应制得的,还有一些5-取代的嘧啶-2-硫醇已用于合成新型二硫醚化合物。红外,1 H NMR,13 C NMR和质谱数据证实了新合成化合物的分子结构。在DMSO中检测了这些化合物的紫外光谱行为和ƛ最大这些化合物进行了研究。
