  RETRACTED: Asymmetric synthesis of highly enantioenriched 2-substituted piperidines and 6-substituted piperidine-2-ones by a combination enantioselective hydrazone allylation with ring closing metathesis

  摘要：

  An efficient method for the asymmetric synthesis of highly optically pure 2-substituted piperidines and 6-substituted piperidine-2-ones from aldehydes was developed by a sequence of enantioselective hydrazone allylation and ring closing metathesis. This method was found to be effective for a variety of substrates, showing substrate generality. The method's synthetic utility was illustrated in concise synthesis of the alkaloid (R)-(-)-coniine.

• Asymmetric Petasis Borono‐Mannich Allylation Reactions Catalyzed by Chiral Biphenols
  作者：Yao Jiang、Scott E. Schaus

  DOI：10.1002/anie.201611332

  日期：2017.2

  Chiral biphenols catalyze the asymmetric Petasis borono‐Mannich allylation of aldehydes and amines through the use of a bench‐stable allyldioxaborolane. The reaction proceeds via a two‐step, one‐pot process and requires 2–8 mole % of 3,3′‐Ph2‐BINOL as the optimal catalyst. Under microwave heating the reaction affords chiral homoallylic amines in excellent yields (up to 99 %) and high enantioselectivies

  手性联苯酚通过使用工作台稳定的烯丙基二氧硼杂硼烷催化醛和胺的不对称 Petasis 硼-曼尼希烯丙基化。该反应通过两步一锅法进行，需要 2-8 摩尔%的 3,3'-Ph 2 -BINOL 作为最佳催化剂。在微波加热下，该反应以优异的产率（高达 99%）和高对映选择性（高达 99:1）提供手性高烯丙胺。催化反应是真正的多组分缩合反应，而醛和胺都可以具有广泛的结构和电子特性。在反应中使用巴豆基二氧硼杂硼烷会产生具有反式和顺式非对映异构体的立体发散产物，其与相应的 E-和 Z-硼杂硼烷立体异构体均具有良好的非对映选择性和对映选择性。

  Diisobutylaluminum hydride (DIBAL-H) reduces nitriles to give N-diisobutylaluminum imines, which were asymmetrically allylated with chirally modified allylboron reagents. The corresponding chiral primary homoallylamines were obtained with up to 87% ee.

  The development of a catalytic asymmetric method for the direct aminoallylation of aldehydes is described that gives high asymmetric inductions for a broad range of substrates including both aromatic and aliphatic aldehydes. This method allows for direct isolation of unprotected analytically pure homoallylic amines without chromatography. The unique catalyst system developed for this process involves
