having at least one amino group attached to an aliphatic chain, has been synthesized from (1-thyminyl)thioacetamide in good isolated yields (69–86%). N-[2-(4-Imidazolyl)ethyl](1-thyminyl)thioacetamide was hydrolyzed to its amide on prolonged heating in water. Ammonium sulfide (20–22% solution in water) has found interesting new applications in the efficient synthesis of N-[2-(3-indolyl)ethyl](1-thyminyl)thioacetamide
由(1-胸苷基)硫代乙酰胺合成的一系列新的N-取代的硫代氨基甲酰基衍生物含有组胺,色胺和其他具有至少一个与脂肪族链相连的氨基的部分,分离得率良好(69-86%)。N- [2-(4-咪唑基)乙基](1-胸苷基)硫代乙酰胺在水中长时间加热后水解为酰胺。硫化铵(在水中20-22%的溶液)在N- [2-(3-吲哚基乙基)乙基](1-胸苷基)硫代乙酰胺的高效合成和二氨基链烷烃的位点选择性酰化反应中发现了有趣的新应用,直接从腈开始。
