  摘要：

  钯催化的手性烯胺的不对称烯基化反应，源自(S)-2-(二苯膦甲基)吡咯烷，产生了光学活性α-烯基羰基化合物，并且光学产率很高。手性烯胺中的磷基团在这些钯催化反应中很可能作为手性配体。在与分子内磷烷基团配位的π-烯基钯配合物的过渡态中，阴离子对应物或烯基化试剂被认为在控制对映选择性的等级方面起着重要作用。

  The palladium-catalyzed asymmetric allylations of chiral enamines, derived from (S)-2-(diphenylphosphinomethyl)pyrrolidine, produced optically active α-allyl carbonyl compounds in high optical yields. The phosphino group in the chiral enamines presumably serves as a chiral ligand in these palladium-catalyzed reactions. In the transition states of π-allylpalladium complexes coordinated with the intramolecular phosphine group, the anionic counterparts or allylating reagents are considered to play an important role in controlling of the grade of the enantioselectivity.

  synergistic catalysis for asymmetric allylic alkylation of α-branched β-ketocarbonyls. The use of arene-containing chiral primary amine catalyst led to not only enhanced reaction rate but also reversed chiral induction comparing with its sterically bulky derivative. Both enantiomers of the allylic adducts bearing acyclic all-carbon quaternary stereocenters could be obtained from the same configured chiral aminocatalyst

  我们报告了一种含芳烃的手性伯胺作为双氨基催化剂和配体。用于α-支化β-酮羰基不对称烯丙基烷基化的π-配位氨基催化剂/钯协同催化。与空间庞大的衍生物相比，含芳烃的手性伯胺催化剂的使用不仅提高了反应速率，而且还逆转了手性诱导。带有无环全碳四元立体中心的烯丙基加合物的两种对映异构体都可以从相同配置的手性氨基催化剂中以高效和优异的区域选择性、立体选择性和对映选择性获得。机理研究揭示了一种独特的 Pd-芳烃 π 配位模式，用于有效催化。

  The catalytic asymmetric alkylation of alpha-cyanocarboxylates and acetoacetates with an alkyl halide was performed under phase-transfer conditions to afford compounds which have a chiral quaternary carbon with up to 97% and 94% ee, respectively. As applications of this method, chiral 2-oxindole derivatives and a beta-lactam derivative were synthesized. (C) 2009 Elsevier Ltd. All rights reserved.
