Allylmagnesium, allylindium, and allylbismuth generally showed a preference for axial addition to cyclohexenones. Allylmagnesium was the most stereoselective. Reactions with an α-methylated enone (carvone) were the most selective, except that allylbismuth was unreactive with this substrate.
烯丙基

铋通常优先选择轴向添加到
环己酮中。烯丙基
镁是最具立体选择性的。与α-甲基化的烯酮(
香芹酮)的反应具有最高的选择性,只是烯丙基
铋与该底物没有反应。
