The reaction of allylsilanes with 1,1-dimethoxybutan-3-one was found to proceed selectively on the acetal moiety regardless of the kind of Lewis acid, while the chemoselectivity of the corresponding reaction with 1,1-dimethoxypropan-2-one was changed dramatically by the sort of Lewis acid employed.
无论路易斯酸的种类如何,烯丙基硅烷与 1,1-二甲氧基丁-3-酮的反应都选择性地在缩醛部分上进行,而与 1,1-二甲氧基丙-2-酮的相应反应的化学选择性发生了变化通过使用路易斯酸的种类。
