A series of 4-bromo-5-halo and 4-bromo-5-organometal-2-anilinothiazole derivatives were prepared via the halogen dance (HD) reaction. Subsequent Pd-catalyzed Stille and Suzuki-Miyaura cross-coupling reactions were performed in a sequential manner to obtain novel 4,5-diarylated-2-anilinothiazoles.
通过卤素舞(HD)反应制备了一系列 4-
溴-5-卤素和 4-
溴-5-有机
金属-2-
苯胺噻唑衍
生物。随后依次进行了
钯催化的 Stille 和 Suzuki-Miyaura 交叉偶联反应,得到了新型 4,5-二芳基化-2-
苯胺噻唑。
