  带有树枝状手性麻黄碱部分的新型定义明确的链端官能化聚苯乙烯的合成及其作为高对映选择性二乙基锌的N-二苯基膦酰基芳嘌呤类化合物的应用

  摘要：

  定量合成了一系列新颖的，定义明确的，具有2、4、8和16个手性麻黄碱部分在其超支化链端分布的手性麻油碱部分的链端官能化聚苯乙烯。通过元素分析，FTIR，SEC以及1 H和13 C NMR光谱学充分证实了它们的明确定义的体系结构。这些聚合物的分子量和分子量分布均得到精确控制，链端官能团也得到了明确定义。这些树状手性聚合物在二乙基锌向一系列N的对映选择性加成中充当高度对映选择性的手性配体-二苯基膦酰基芳基丙氨酸。其中，在链末端具有八个麻黄碱部分的手性树枝状聚合物以高至高收率提供了对映异构体富集的膦酰基酰胺，其对映选择性高达93％ee。所获得的对映选择性与使用N-苄基麻黄碱及其相应的共聚物作为手性配体所获得的对映选择性相当。

• Catalytic Enantioselective Addition of Dialkylzinc to <i>N</i>-Diphenylphosphinoylimines. A Practical Synthesis of α-Chiral Amines

  The enantioselective addition of dialkylzinc reagents to N-diphenylphosphinoylimines derived from aryl-, furyl-, and cyclopropylaldehydes is efficiently catalyzed by a copper(II) triflate/(R,R)-MeDUPHOS complex. The yields are high (51-98%), and the enantiomeric excesses vary from 85 to 96%. This route provides a practical route to alpha-chiral amines.

  Chiral N,N-dialkylnorephedrines supported on polystyrene resin catalyse the enantioselective addition of dialkylzincs to N-diphenylphosphinylimine, affording optically active N-diphenylphosphinylamines with high enantiomeric excess. The influence on the enantioselectivity of the carbon-chain spacer between the chiral function and polymer resin has been examined. Reaction temperature- and solvent-dependency on the chiral polymer-catalysed reaction has also been examined.

  A series of novel well-defined chain-end-functionalized polystyrenes having 2, 4, 8, and 16 chiral ephedrine moieties dendritically distributed at their hyperbranched chain-ends were quantitatively synthesized. Their well-defined architectures were fully confirmed by elemental analysis, FTIR, SEC as well as by 1H and 13C NMR spectroscopies. These polymers were precisely controlled in the molecular

  A new type of chiral copper complexes of N,P-ferrocenyl ligands with central and planar chirality as efficient catalyst was applied to the enantioselective addition of diethylzinc to N-diphenylphosphinoylimines. The (R)- and (s)-enantiomers of the addition reaction were obtained for this transformation. In the presence of 6 mol % of bidentate ligand 1 and 12 mol % of Cu(OTf)(2), the asymmetric addition process affords N-diphenylphosphinoylamides in up to 97% ee and 95% yields. (c) 2005 Elsevier Ltd.
