A convenient and highly efficient protocol for one-pot synthesis of some novel N-heterocycle methyl-O-oxime ethers is described. In this method, three-component coupling of different types of ketoximes, with methylene iodide and nitrogen heterocycles, including imidazoles, benzimidazole, benzotriazole, and theophylline in the presence of an equimolar mixture of K2CO3/Et3N in refluxing MeCN furnished
描述了一种方便且高效的方案,用于一锅合成一些新型的N-杂环甲基-O-肟醚。在此方法中,在回流的MeCN中,在K 2 CO 3 / Et 3 N等摩尔混合物存在下,将不同类型的酮肟与亚甲基碘和氮杂环(包括咪唑,苯并咪唑,苯并三唑和茶碱)进行三组分偶联。相应的N-杂环甲基-O-肟醚收率很高。该方法对于合成各种结构多样的N-杂环甲基-O非常高效-肟醚。讨论了反应中间体的量子力学研究结果。 三组分反应(3CR)-肟-O-肟醚-碘甲烷-N-杂环
