In contrast to their reactions with other (E)-allylic alcohols, the amide-acetals (1a, b) react with (E)-1-trimethylsilylpent-3-en-2-ol to give mixtures of product amides in which the threo-diasteroisomers marginally predominate.
相反他们的反应与其它(ë) -烯丙基醇,酰胺缩醛(1a中,b)与反应(ë)-1-三甲基硅烷基-3-烯-2-醇,得到产物的酰胺的混合物,其中的苏-非对映异构体占主导地位。
