  Taking the F out of FLP: Simple Lewis Acid–Base Pairs for Mild Reductions with Neutral Boranes via Borenium Ion Catalysis

  摘要：

  Discrete three-coordinate borenium salts 1c and 1d are accessed by cooperative Lewis acid-base pair-mediated heterolytic splitting of the B-H bond in pinacolborane by B(C6F5)(3)center dot DABCO and Ph3C+/DABCO, respectively. The resulting salts are competent catalysts in the reduction of a broad range of imines and can be generated in situ. Moreover, a mechanistic framework for borenium catalysis based on experimental evidence is proposed. The reaction is suggested to proceed by borenium activation of the imine substrate followed by counterintuitive hydride delivery from HBPin (with the assistance of DABCO) rather than from the HB(C6F5)(3)(-) anion, contrary to typical mechanisms of reduction in FLP systems.

• Ortho Alkylation of Aromatic Ketimine with Functionalized Alkene by Rh(I) Catalyst
  作者：Sung-Gon Lim、Jeong-Ae Ahn、Chul-Ho Jun

  DOI：10.1021/ol048095n

  日期：2004.12.1

  reaction of the imine of aromatic ketones with functionalized alkenes was performed under a catalytic amount of (PPh3)3RhCl, and corresponding ortho-alkylated ketones were obtained after hydrolysis. A variety of functional groups in the alkene were tolerated in this ortho alkylation. This procedure expands the scope of ortho alkylation to the direct ortho functionalization of aromatic ketones.

  development of simple, low-cost, efficient, and sustainable routes to enantiomerically pure amines is a topic of extraordinary interest, specially in view of future industrial applications. In this context, we wish to report a chemical and stereochemical efficient synthesis of chiral amines through the Lewis base activated trichlorosilane reduction of ketimines. An organocatalyst, easily prepared in a single

  开发对映异构纯胺的简单、低成本、高效和可持续的路线是一个非常有趣的话题，特别是考虑到未来的工业应用。在这种情况下，我们希望通过路易斯碱活化的三氯硅烷还原酮亚胺来报告手性胺的化学和立体化学有效合成。有机催化剂，通过吡啶甲酸和市售的 1,1'-联萘二胺的缩合很容易在一个步骤中制备，是这种无金属方法的关键要素，它允许以高产率合成手性仲胺和伯胺，并且立体选择性。值得注意的是，此类催化剂能够促进 N-烷基酮亚胺的还原，通常以定量收率和高达 87% 的对映选择性；值得一提的是，对于此类转化，迄今为止仅报道了一种其他有机催化系统。(© Wiley-VCH Verlag GmbH & Co.

  The influence of the alcohol, as the hydrogen donor, on the efficiency and selectivity of the asymmetric transfer hydrogenation (ATH) of imines is reported for the first time. This discovery not only leads to a highly enantioselective access to N‐aryl and N‐alkyl amines, but also provides new insight into the mechanism of the ATH of imines. Both experimental and computational studies provide support
