3 -symmetric oxazole derivatives are synthesized via the Suzuki-Miyaura cross-coupling and van Leusen oxazolesynthesis. Here, bis- and triscarboxaldehydes were obtained via the Suzuki-Miyaura cross-coupling and further treated with p-toluenesulfonylmethyl isocyanide (TosMIC) in the presence of potassium carbonate as a base and methanol as a solvent to deliver the corresponding oxazole derivatives.
C 2 - 和 C 3 - 对称恶唑衍生物均通过 Suzuki-Miyaura 交叉偶联和 van Leusen 恶唑合成法合成。在这里,通过 Suzuki-Miyaura 交叉偶联获得双和三甲醛,并在碳酸钾作为碱和甲醇作为溶剂的存在下,用对甲苯磺酰甲基异氰化物 (TosMIC) 进一步处理,以提供相应的恶唑衍生物。
