A series of pyrido[2,3-d]pyrimidine derivatives were synthesized by the three-component reaction of aromatic aldehyde, malononitrile and 6-amino-4-hydroxy-2-mercaptopyrimidine catalyzed by sodium lauryl sulfate (SDS) in aqueous media. It was interesting that further aromatization took place automatically. This method provides several advantages such as easier work-up, milder reaction conditions and environmental friendly.
一系列吡啶并[2,3-d]嘧啶衍生物通过芳香醛、马来酸二腈和6-氨基-4-羟基-2-巯基嘧啶在水性介质中由十二烷基硫酸钠(SDS)催化的三组分反应合成。有趣的是进一步的芳香化自动发生。该方法具有易于操作、反应条件温和和环保等几个优点。
