  Investigation of the importance of nitrogen substituents in a N–P chiral ligand for enantioselective allylic alkylation

  摘要：

  The synthesis of three chiral chelate nitrogen-phosphorus (S)-valine derived ligands with the potential fur stereogenic nitrogen donation is described. In palladium catalysed allylic substitution reactions the ligands induced varying enantioselectivities ranging From 92%, e.e. of the (R)-enantiomer to 83% e.e. of the (S)-enantiomer. Structural and spectroscopic investigations into the origin of this effect were conducted, but were inconclusive. However, the importance of the consideration of N-substituents in such systems is highlighted. (C) 2001 Elsevier Science Ltd. All rights reserved.

  钽酰氨基醇盐配合物对氨基丙二烯的不对称催化分子内加氢胺化

  摘要：

  制备了一系列手性双齿氨基烷氧化物配体的钽配合物。得到一种配合物Ta（NMe 2）3 [-OCPh 2 CH（CHMe 2）N（c -C 6 H 11）-]的晶体结构。不同于先前描述的具有这些配体的钛配合物，它们与桥连的氧原子二聚，该钽配合物是具有近似三角-双锥体几何结构的单体。检查所得复合物的原位活性用于氨基丙烯的不对称催化氨化/环化反应。在135℃下以5 mol％的催化剂负载量，将6-甲基庚-4,5-二烯基胺环化为2-（2-甲基丙烯基）吡咯烷，观察到高达80％ee的对映选择性。

• Concepts for ligand design in asymmetric catalysis: a study of chiral amino thiol ligands
  作者：James C. Anderson、Rachel Cubbon、Michael Harding、Daniel S. James

  DOI：10.1016/s0957-4166(98)00344-9

  日期：1998.10

  A series of new chiral sulfur-nitrogen chelate ligands, derived from amino acids, has been synthesised rationally. Fruitless experiments into catalytic asymmetric conjugate additions and desymmetrisation of meso-epoxides led us to analyse our ligands in the catalytic asymmetric addition of diethylzinc to aromatic aldehydes. These latter experiments were successful with chiral benzylic alcohols being obtained in up to 82% enantiomeric excess. (C) 1998 Elsevier Science Ltd. All rights reserved.
• Sterically encumbered chiral amino alcohols for titanium-catalyzed asymmetric intramolecular hydroamination of aminoallenes
  作者：Amanda J. Hickman、Lauren D. Hughs、Casey M. Jones、Hanhan Li、Joanne E. Redford、Samuel J. Sobelman、J. Andrew Kouzelos、Adam. R. Johnson

  日期：2009.6

  A variety of sterically encumbered amino alcohol ligands were prepared in a two-step modular synthesis. The titanium complexes of these ligands were prepared in situ and used as catalysts for hydroamination. The intramolecular hydroamination of 6-methyl-hepta-4,5-dienylamine at 135 degrees C with 5 mol % catalyst gave exclusively 2-(2-methyl-propenyl)-pyrrolidine with enantiomeric excesses up to 16%.
