δ-Fluoro and δ,δ-difluorohomoallylic alcohol derivatives can be efficiently prepared by LiAlH4 reduction of the δ,δ-difluoroallylic alcohols and the γ-chlorodifluoromethylallylic alcohols, respectively, through regioselective SN2′ reaction, in which the free hydroxyl group is essential for the reaction to proceed.
可以通过区域选择性SN2'反应分别通过LiAlH 4还原δ,δ-二氟烯丙基醇和γ-氯二氟甲基烯丙基醇来有效地制备δ-Fluoro和δ,δ-difluorohomoallylic醇衍生物,其中游离羟基是必不可少的反应进行。
