compound, diethyl acetamidomalonate, can efficiently proceed in the presence of CuI and NaH in DMSO to give diethyl acetamido(aryl)malonates, which may be useful precursors for α-arylglycines, in good yields. Although the reaction with another methine substrate, ethyl 2-cyanopropionate, also affords the expected coupling products, no substitution products are obtained in the case of diethyl methylmalonate
芳基碘化物与活化的次甲基化合物乙酰氨基丙二酸二乙酯的反应可以在 CuI 和 NaH 的 DMSO 中有效进行,得到乙酰氨基(芳基)丙二酸二乙酯,其可能是 α-芳基甘氨酸的有用前体,收率良好。尽管与另一种次甲基底物 2-氰基丙酸乙酯的反应也提供了预期的偶联产物,但在甲基丙二酸二乙酯、芳烃以及正在形成的酯的氧化偶联化合物的情况下没有获得取代产物。
