regioselective nucleophilic ring opening and the deprotonation of α,β-epoxy-γ,δ-vinyl-silanes with nitrogen, sulfur and carbon nucleophiles. In an original way, our results point out the α,β-epoxy-silane-like or vinyloxirane-like behavior of α,β-epoxy-γ,δ-vinyl-silanes according to their configuration and to the type of the nucleophile. Furthermore we report an easy stereoselective access to α-alkylated-α'-silylated-β
这项工作描述了区域选择性亲核开环和 α,β-环氧-γ,δ-乙烯基-硅烷与氮、硫和碳亲核试剂的去质子化。我们的结果以一种原始的方式指出了 α,β-环氧-γ,δ-乙烯基-硅烷根据它们的构型和亲核试剂的类型的 α,β-环氧-硅烷类或乙烯基环氧乙烷类行为。此外,我们报告了对 α-烷基化-α'-甲硅烷基化-β,γ-不饱和酮的简单立体选择性访问。
