An I-mediated annulation of 3-aminopyrazoles with indole-3-carboxaldehydes has been demonstrated for the first time. This tandem strategy allows the facile construction of indole-pyrimidine-pyrazole-fused tetracyclic heteroarenes that are otherwise inaccessible by the existing methods. These fused heterocycles exhibited enhanced antifungal activities against and compared with commercial Xemium fungicide.
首次证明了3-氨基吡唑与吲哚-3-甲醛的I介导环化反应。这种串联策略能够轻松构建吲哚-嘧啶-吡唑稠合的四环杂芳烃,而现有方法无法获得这些化合物。与市售的Xemium杀菌剂相比,这些稠合杂环对[具体真菌名称1]和[具体真菌名称2]表现出增强的抗真菌活性。
