Abstract New quinoxaline derivatives were prepared by the reaction of 2-hydroxyquinoxaline 1 and alkyl or alkylaminoalkyl halides in dimethylformamide using potassium carbonate as a base. The hydroxyl group was readily converted into a thiol function by treatment with phosphorus pentasulfide and/or Lawesson's reagent in pyridine, and the subsequent alkylation of the thiol group was carried out under
摘要 以碳酸钾为碱,2-羟基喹喔啉1与烷基或烷基氨基烷基卤化物在二甲基甲酰胺中反应制备新型喹喔啉衍生物。通过在吡啶中用五硫化二磷和/或劳森试剂处理,羟基很容易转化为硫醇官能团,随后硫醇基团的烷基化在相转移催化剂条件下进行。1的氯化用磷酰氯进行。烷基氨基侧链支化到 2-OH、2-SH 和 2-Cl 喹喔啉导致几种化合物的合成。还报道了 2-羟基 7-硝基喹喔啉的合成和烷基化。
