An effective one-pot multicomponent synthesis of pyrazolo[3,4-d]pyrimidinone derivatives through the tandem heterocyclization of hydrazine, methylenemalononitrile and aldehyde has been developed. This highly effective method includes nucleophilic addition, heterocyclization, substitution, intramolecular Pinner, Dimroth rearrangement and dehydroaromatization.
通过肼,亚甲基丙二腈和醛的串联杂环化,开发了一种有效的一锅多组分合成吡唑并[3,4- d ]嘧啶酮衍生物的方法。这种高效的方法包括亲核加成,杂环化,取代,分子内Pinner,Dimroth重排和脱氢芳香化。
