  Synthesis of enantiomerically enriched amines by chiral ligand mediated addition of organolithium reagents to imines

  摘要：

  The effect of the imine and ligand structure on the enantioselective addition or organolithiums to imines has been studied. Thus, (-)-sparteine-mediated additions or MeLi and or n-BuLi to p-anisidine derived phenylimine 1a afforded the corresponding amines with modest e.e.s. The use of bulkier or more reactive imines (naphthyl or toss I imines) resulted ill loss Of enantioselectivity. The best enantioinduction with this ligand,Nas obtained with enolizable imines 8 and 10. When bis(oxazolidines) were used as chiral ligands, a strong influence of their structure in the enantioselectivity or the addition of MeLi and n-BuLi to phenylimine 1a was observed.

  A series of chiral cyclometalated iridium complexes have been synthesised by cyclometalating chiral 2-aryl-oxazoline and imidazoline ligands with [Cp*IrCl2]2. These iridacycles were studied for asymmetric transfer hydrogenation reactions with formic acid as the hydrogen source and were found to display various activities and enantioselectivities, with the most effective ones affording up to 63% ee

  The first enantioselective organocatalytic reductive amination reaction has been accomplished. The development of a new chiral phosphoric acid catalyst has provided a convenient strategy for the enantioselective construction of protected primary amines and provided a highly stereoselective method for the reductive amination of heterocyclic amines. A diverse spectrum of ketone and amine substrates can

  第一个对映选择性有机催化还原胺化反应已经完成。新型手性磷酸催化剂的开发为受保护伯胺的对映选择性构建提供了一种方便的策略，并为杂环胺的还原胺化提供了一种高度立体选择性的方法。可以以高产率和出色的对映选择性容纳各种不同的酮和胺底物。这种新协议实现了还原胺化与亚胺还原的关键优势，因为从烷基-烷基酮衍生的酮亚胺对分离不稳定，使用这种直接有机催化还原胺化可以全面绕过这一基本限制。

  The enantioselective addition of organolithium reagents to N-anisyl aldimines promoted by chiral bisoxazolines and (-)-sparteine as external ligands is described. This reaction proceeds readily with a wide range of aldimine substrates (aliphatic, aromatic, olefinic) and organolithium nucleophiles (Me, n-Bu, Ph, vinyl) in excellent yields (81-99%) and with high enantioselectivities (up to 95.5:4.5 er)

  描述了在手性双恶唑啉和(-)-金雀花碱作为外部配体的促进下，有机锂试剂对映选择性加成到N-茴香基醛亚胺上。该反应可以使用多种醛亚胺底物（脂肪族、芳香族、烯烃）和有机锂亲核试剂（Me、n-Bu、Ph、乙烯基）轻松进行，收率优异（81-99%），并且具有高对映选择性（高达 95.5： 4.5 尔）。外部配体可以亚化学计量的量使用，尽管对映选择性略有减弱。对双恶唑啉结构特征的系统评估揭示了 C(4) 取代基的主要贡献和桥接取代基的次要影响。计算分析 (PM3) 为对映选择性的起源提供了清晰的合理解释。

Alternatively, the amination of alcohols by the use of borrowing hydrogen methodology has proven a highly atom economical and green method for the production of amines without an external reductant, as the alcohol substrate serves as the H2 donor. A catalytic enantioselective variant of this

  An oxidative kinetic resolution of racemic acyclic amines was developed using an imine derivative as the resolving reagent and chiral phosphoric acid as the catalyst to give enantiomers in good yields with high to excellent enantioselectivities. The key to success of the title reaction was the equilibrium control by adjusting the ratio of the resolving reagent, and unique enantiodivergence was observed
