The asymmetric synthesis of fluorinated isoindolinones has been achieved by a palladium‐catalyzed aminocarbonylation reaction of the corresponding α‐fluoroalkyl o‐iodobenzylamines. A base‐mediated anti β‐hydride elimination process was suggested to explain the partial erosion of the optical purity observed in some cases. This mechanistic rationale enabled the minimization of this partial racemization
氟化异吲哚啉酮的不对称合成是通过相应α-氟代烷基邻碘苄基胺的钯催化氨基羰基化反应实现的。建议使用碱介导的抗β-氢化物消除工艺来解释在某些情况下观察到的光学纯度的部分侵蚀。这种机械原理可以通过微调碱基的p K a来使这种部分消旋作用最小化。
