Abstract

An efficient synthesis of new aminodimethyl(methylsulfonyl)dihydropyrido[2,3-d]pyrimidinedione derivatives via the three components reaction of 2-methanesulfonylacetonitrile, 1,3-dimethyl-6-amino-uracil, and aromatic aldehydes in the presence of [HO-(CH₂)₂-NH₂][CH₃CO₂H] and Fe₃O₄@SiO₂@[O-(CH₂)₂-NH₂][CH₃CO₂H] as novel heterogeneous magnetic nanocatalyst was described. The Fe₃O₄@SiO₂@[O-(CH₂)₂-NH₂][CH₃CO₂H] as nanocatalyst can be easily separated from the reaction mixture by an external magnet, recycled, and reused several times without any significant decrease in catalytic activity. These methods showed several advantages, including high yields, easy operation, and environment-friendly protocols.

Fe3O4@SiO2@[O-(CH2)2- nh2][CH3CO2H]纳米催化剂下新型氨基二甲基（甲基磺酰基）二氢吡啶[2,3-d]嘧啶二酮衍生物的制备

以[HO-(CH2)2- nh2][CH3CO2H]和Fe3O4@SiO2@[O-(CH2)2- nh2][CH3CO2H]为新型非均相磁性纳米催化剂，通过2-甲磺基乙腈、1,3-二甲基-6-氨基尿嘧啶和芳香醛的三组分反应，高效合成了新型氨基二甲基（甲基磺酰）二氢吡啶[2,3-d]嘧啶二酮衍生物。Fe3O4@SiO2@[O-(CH2)2-NH2][CH3CO2H]作为纳米催化剂，可以很容易地通过外部磁铁从反应混合物中分离出来，并可循环使用，多次重复使用，而催化活性没有明显下降。这些方法具有产率高、操作简单、环境友好等优点。
