An effective one-pot, regioselective double Suzuki coupling of 2,4-dichloropyrimidine has been developed, which enables the quick and efficient synthesis of diarylated pyrimidines. The choice of solvent proved critical to the success of this reaction sequence, with alcoholic solvent mixtures affording much greater reactivity and requiring correspondingly lower temperatures than the use of polar aprotic solvents.
通过一项高效的一锅法区域选择性双Suzuki偶联反应,已开发出2,4-二氯嘧啶的合成方法,该方法能够迅速且高效地合成二芳基化的嘧啶。溶剂的选择被证明对这一反应序列的成功至关重要,使用醇类溶剂混合物比使用极性非质子溶剂能提供更高的反应活性,并且相应地需要在更低的温度下进行。
