• Palladium‐ and Rhodium‐Catalyzed Dynamic Kinetic Resolution of Racemic Internal Allenes Towards Chiral Pyrazoles
  作者：Lukas J. Hilpert、Simon V. Sieger、Alexander M. Haydl、Bernhard Breit

  DOI：10.1002/anie.201812984

  日期：2019.3.11

  resolution (DKR) of racemic allenes leading to N‐allylated pyrazoles is described. Such compounds are of enormous interest in medicinal chemistry as certified drugs and potential drug candidates. The new methods feature high chemo‐, regio‐ and enantioselectivities aside from displaying a broad substrate scope and functional group compatibility. A mechanistic rational accounting for allene racemization and trans‐alkene

  描述了外消旋烯的互补的Pd和Rh催化的动态动力学拆分（DKR），导致N-烯丙基化的吡唑。这类化合物作为认证药物和潜在候选药物在药物化学中引起了极大的兴趣。这些新方法除了具有广泛的底物范围和官能团相容性外，还具有较高的化学，区域和对映选择性。讨论了合理的机制来解释异戊二烯外消旋和反式烯烃的选择性。
