Treatment of γ-fluoroallylic phosphate with various lower-ordered cyanocuprates derived from Grignard reagents, organolithium, and organozincs gave the corresponding SN2Ⲡproducts having a fluorine atom at a quaternary carbon center in excellent yields. This system could be successfully extended to the chiral version, enantiomerically pure fluorine-containing materials also being obtained in high yield.
使用从Grignard试剂、有机锂试剂和有机锌试剂衍生的各种低级氰基铜酸盐处理γ-氟代烯丙基磷酸盐,能够以优异的产率获得在季碳中心具有氟原子的相应SN2'产物。该体系可成功扩展至手性版本,同样以高产率获得了含有氟的手性纯材料。
