of N-alkoxycarbonylamino sulfones (α-amido sulfones) with allyltrimethylsilane in the presence of gallium(III) chloride (5 mol %) proceeded smoothly to afford the corresponding protected homoallylamines in high yields (82―96%). As an application of this methodology, two-step synthesis of biologically active natural products, 2,6-disubstituted piperidine alkaloid derivatives was carried out.
N-烷氧基羰基氨基砜(α-酰氨基砜)与烯丙基三甲基硅烷在氯化镓(III)(5 mol %)存在下的樱井反应顺利进行,以高产率(82-96%)得到相应的保护高烯丙胺。作为该方法的应用,进行了生物活性天然产物 2,6-二取代哌啶生物碱衍生物的两步合成。
