Diene to meet: A palladium‐catalyzed cross‐coupling reaction between alkyl‐substituted olefins and acrylates gives the corresponding butadienes in moderate yield and stereoselectivity. This atom‐economical reaction, which forms C–C bonds, tolerates a wide range of allylic and homoallylic alcohols, and acrylates (see scheme; TIPS =triisopropylsilyl). The methodology was applied to the synthesis of the
满足的二烯:烷基取代的烯烃与丙烯酸酯之间的钯催化交叉偶联反应以中等收率和立体选择性提供了相应的丁二烯。这种形成C- C键的原子经济反应可耐受各种烯丙基和均烯丙基醇以及丙烯酸酯(请参见方案; TIPS =三异丙基甲硅烷基)。该方法应用于棕榈油内酯A的C13–C21片段的合成。
