In acetic acid medium, 2-chloro-4,6-dimorpholin-4-yl-[1,3,5]triazine undergoes amination by bifunctional heterocyclic compounds containing both amino and thioamide groups. The reactions are high-yielding and selective; the thioamide functions are unaffected under the requisite conditions. The reactions do not proceed in satisfactory yields in other solvents and, thus, require acetic acid. The resulting
在乙酸介质中,2-氯-4,6-二吗啉-4-基-[1,3,5]三嗪被同时含有氨基和硫酰胺基团的双官能杂环化合物胺化。反应是高产率和选择性的。硫酰胺的功能在必要条件下不受影响。反应在其他溶剂中不能以令人满意的产率进行,因此需要乙酸。由多个生物学上相关的残基组成的所得硫代酰胺易于在硫(硫代硫酮)中心烷基化,以在后续步骤中提供新的硫醚。
