Abstract
A convenient and practical method for the synthesis of 2-alkylthio-4-amino-5-cyano-6-aryl(alkyl)pyrimidines has been developed via a three-component, one-pot reaction from aldehydes, malononitrile and S-alkylisothiouronium salts in water at room temperature. A series of polysubstituted pyrimidines were prepared by this method in moderate to excellent yields. In addition, two kinds of pyrimidine-fused heterocyclic derivatives with potential pharmacological activity were constructed from our 2-alkylthio-4-amino-5-cyano-6-arylpyrimidines.
摘要
一种方便实用的 2-烷硫基-4-氨基-5-氰基-6-芳基（烷基）嘧啶的合成方法，通过在水相中室温下，由醛、丙二腈和 S-烷基亚硫脲盐进行三组分一锅反应来实现。通过该方法可以中等至优异的收率制备一系列多取代嘧啶。此外，还可以从我们的 2-烷硫基-4-氨基-5-氰基-6-芳基嘧啶构建具有潜在药理活性的两种嘧啶稠合杂环衍生物。
