摘 要: 由烯基膦亚胺 (1)与二硫化碳、肼的串联aza Wittig反应制得了 2 硫代 3 氨基 5 芳基亚甲基 4 咪唑啉二酮 (3) ,再利用 (3)的S 烷基化反应合成了新型 2 烷硫基 3 氨基 5 芳基亚甲基 4H 咪唑啉 4 酮 (4 )。讨论了反应的条件和所合成化合物的波谱性质。其结构经元素分析、IR、1HNMR和MS测试确证。在室温或 6 0~ 80℃反应条件下 ,分别以 6 3%~ 97%和 5 3%~ 76 %的产率得到化合物 3a~ 3d和 4a~ 4f。 2-Thio-3-amino-5-arylmethylene-4-imidazolidinones(3) were prepared via the tandem aza-Wittig reaction of vinyliminophosphoranes(1) with carbon disulfide and hydrazines. Then 2-alkylthio-3-amino-5-arylmethylene-4H-imidazolin-4-ones(4) were synthesized by S-alkylation of compound 3. The reaction conditions were discussed, the spectral properties of the synthesized compounds were elucidated, and their structures were confirmed by elemental analysis, IR, 1H NMR and MS. At room temperature or 60~80 ℃ the compounds 3a~3d and 4a~4f were obtained in yields of 63%~97% and 53%~76% respectively.
