synthesis of functionalized 4- or 5-(hetero)arylpyrimidines via decarboxylativecross-coupling reaction from readily available pyrimidine-4- and pyrimidine-5-carboxylates was described. In the presence of dual-catalyst system of Pd(PPh3)4/Cu2O, the reaction proceeds smoothly, tolerates a variety of functional groups, and provides easy access to the synthesis of different (hetero)arylpyrimidines compounds.
描述了一种直接的方法,用于从容易获得的嘧啶-4-和嘧啶-5-羧酸酯上通过脱羧交叉偶联反应合成官能化的4-或5-(杂)芳基嘧啶。在Pd(PPh 3)4 / Cu 2 O的双催化剂体系存在下,反应平稳进行,可以耐受各种官能团,并易于合成不同的(杂)芳基嘧啶化合物。
