cinnamates and β-silyl acrylates by a regiospecific reductive C-silylation using Mg/silyl chloride/DMF system at room temperature. These reductive C-silylation conditions have also been applied to δ-aryl substituted dienoates wherein silylation took place at the δ-position leading to the synthesis of single regioisomeric allylsilanes with very high stereoselectivity.
β-芳基-β-甲硅烷基和β,β-二甲硅烷基丙酸酯已通过肉桂和β-甲硅烷基丙烯酸酯在室温下使用Mg /甲硅烷基氯/ DMF系统通过区域特异性还原C-硅烷化反应合成。这些还原性C-甲硅烷基化条件也已应用于δ-芳基取代的二烯酸酯,其中甲硅烷基化发生在δ-位,从而导致具有非常高的立体选择性的单一区域异构烯丙基硅烷的合成。
