New heterocyclic compounds containing pyrazol‐5‐one coupled with benzimidazole, benzothiazole, benzoxazole, quinoline, naphthyridin, and pyrazole were synthesized. Comparative investigations to synthesize these interesting classes of heterocyclic compounds through conventional heating or under microwave‐irradiation conditions were presented. Synthesized compounds 1a, 2a, 4k, 3a, c, 5a, b, 6b, 7a, b
合成了含有吡唑-5-的新型杂环化合物与苯并咪唑、苯并噻唑、苯并恶唑、喹啉、萘啶和吡唑偶联。介绍了通过常规加热或在微波辐射条件下合成这些有趣类别的杂环化合物的比较研究。对合成的化合物 1a、2a、4k、3a、c、5a、b、6b、7a、b、d、8a 和 9a 的抗肿瘤活性进行了评估。这些化合物中的一些表现出有希望的抗肿瘤活性。
