  Ligand-Controlled Palladium-Catalyzed Regiodivergent Suzuki–Miyaura Cross-Coupling of Allylboronates and Aryl Halides

  摘要：

  An orthogonal set of catalyst systems has been developed for the Suzuki-Miyaura coupling of 3,3-disubstituted and 3-monosubstituted allylboronates with (hetero)aryl halides. These methods allow for the highly selective preparation of either the alpha- or the gamma-isomeric coupling product.

  Completely linear: The title reaction provides an effective means to access a wide range of prenylated arenes and “skipped dienes” in a completely linear‐selective fashion, as demonstrated by a concise synthesis of the anti‐HIV natural product siamenol. DFT calculations shed light on the origin of the excellent regioselectivity observed with the current Pd‐based catalyst system.

  完全线性：标题反应提供了一种有效的方法，可以以完全线性选择性的方式获得广泛的异戊二烯化芳烃和“跳过的二烯”，如抗 HIV 天然产物 siamenol 的简明合成所证明的那样。DFT 计算揭示了当前 Pd 基催化剂体系观察到的优异区域选择性的起源。
