• Pd(II)-catalyzed Enantioselective Beta-Methylene C(sp3)–H Bond Activation

  Chiral acetyl-protected aminoethyl quinoline (APAQ), pyridine and imazoline ligands are disclosed that enable Pd (II)-catalyzed enantioselective arylation or heteroarylation of ubiquitous prochiral β-methylene C—H bonds of aliphatic amides offers an alternative disconnection for constructing β-chiral centers. Systematic tuning of the ligand structure reveals that a six-membered instead of a five-membered chelation of these types of ligands with the Pd(II) is important for accelerating the C(sp 3 )-H activation thereby achieving enantioselectivity for quinoline and pyridine ligands.

  披露了手性乙酰保护氨基乙基喹啉（APAQ）、吡啶和咪唑啉配体，这些配体使Pd（II）催化的对丙烷酰胺的普遍的原始手性β-亚甲基C-H键进行对芳基或杂芳基化的不对称选择性取代反应成为可能，为构建β-手性中心提供了另一种断裂途径。通过系统调整配体结构发现，这些类型的配体与Pd（II）的六元环而不是五元环的螯合对于加速C（sp3）-H键的活化至关重要，从而实现喹啉和吡啶配体的对映选择性。

  本研究公开了手性乙酰基保护的氨基乙基喹啉 (APAQ)、吡啶和咪唑啉配体，这些配体能够在钯(II)催化下对无处不在的脂肪族酰胺的原手性 β-亚甲基 C-H 键进行对映选择性芳基化或杂芳基化，为构建 β-手性中心提供了另一种断开方式。配体结构的系统调整表明，这些配体与 Pd(II) 的六元螯合而非五元螯合对于加速 C(sp3)-H 活化非常重要，从而实现了喹啉和吡啶配体的对映选择性。
