An efficient one-pot synthesis of fused pyridine derivatives (including pyrazolo[3,4-b]pyridine and pyrido[2,3-d]pyrimidine) by three-component reaction of aldehyde, acyl acetonitrile, and electron-rich amino heterocycles (including aminopyrazole and aminouracils) in ionicliquid is reported. This new protocol has the advantages of environmental friendliness, higher yields, shorter reaction times,
通过醛,酰基乙腈和富电子氨基杂环的三组分反应,有效地一锅合成熔融的吡啶衍生物(包括吡唑并[3,4- b ]吡啶和吡啶[2,3- d ]嘧啶)包括离子液体中的氨基吡唑和氨基尿嘧啶在内。该新方案具有环境友好,产率高,反应时间短和操作方便的优点。
