Novel 2-phenoxy-N-phenylacetamide hybrids with heterocyclic scaffolds such as thiazoles, imidazoles, benzimidazoles, and benzothiazoles were synthesized efficiently in this study. The reaction of the appropriate α-haloketone with the corresponding thioamide derivatives in EtOH/DMF at reflux in the presence of a few drops of TEA produced good yields of 2-aryl- or heteroarylthiazoles. A one-pot three-component
本研究高效合成了具有噻唑、咪唑、苯并咪唑和苯并噻唑等杂环骨架的新型 2-苯氧基-N-苯基乙酰胺杂化物。在 EtOH/DMF 中,在几滴 TEA 存在下,适当的 α-卤代酮与相应的硫代酰胺衍生物在回流下的反应产生了良好的 2-芳基-或杂芳基噻唑收率。1,2-二酮与醛和醋酸铵在甲醇中回流的一锅三组分反应产生咪唑衍生物。通过适当的醛与o的反应合成苯并咪唑、苯并噻唑或咪唑并 [4,5- b ] 吡啶也是可行的-苯二胺、2-氨基苯硫酚或 2,3-二氨基吡啶,分别在乙醇中在 NaHSO 3存在下回流。使用光谱数据和元素分析验证了新化合物的结构。
