with various carboxylates and amines in the presence of tetrakis(triphenylphosphine)palladium(0) catalyst to give the corresponding gamma-fluoroalkylated (E)-allylic alcohol derivatives and amines, respectively, in excellent yields. In almost all cases, no other regio- and stereoisomers were produced. Application of this palladium-catalyzed allylic substitution reaction to various nonracemic mesylates
在四(三苯基膦)钯(0)催化剂存在下,α-氟代烷基化的烯丙基甲磺酸酯与各种羧酸盐和胺反应,以优异的产率分别得到相应的γ-氟代烷基化的(E)-烯丙基醇衍生物和胺。在几乎所有情况下,均未产生其他区域和立体异构体。将该钯催化的烯丙基取代反应应用于各种非外消旋的甲磺酸酯,得到手性γ-氟烷基化的烯丙基醇衍生物和胺,而不会因反应损失任何对映体过量。
