A new method for preparation of functionalized enamides by a nickel-catalyzed multicomponent coupling of ynamides, aldehydes, and silane has been developed. The coupling reaction proceeded in the presence of a nickel-IMes catalyst to give the corresponding gamma-silyloxyenamide derivative, which has an allylic alcohol moiety in the molecule, in a highly stereoselective manner.
已开发出一种通过乙酰胺,乙醛和硅烷的镍催化多组分偶联制备官能化酰胺的新方法。偶联反应在镍-IMes催化剂的存在下进行,以高度立体选择性的方式得到相应的γ-甲硅烷基氧化烯酰胺衍生物,该衍生物在分子中具有烯丙基醇部分。
