    摘要:
    Ligand displacement of methyl 2-pyrrolidone-5(S)-carboxylate (5(S)-MEPYH) from Rh2-(5(S)-MEPY)4 by a soluble polyethylene-bound 2-pyrrolidone-5(S)-carboxylate produced a recoverable dirhodium(II) catalyst whose effectiveness was demonstrated by high enantioselection for intramolecular cyclo-propanation of 3-methyl-2-buten-1-yl diazoacetate (98% ee) and intramolecular C-H insertion of 2-methoxyethyl diazoacetate (72% ee) as well as by catalyst recovery and reuse seven times.

    摘要:
     抽象的 在此,我们报道了可见光介导的钯催化三组分自由基极性交叉碳胺化反应,1,3-二烯或丙二烯与重氮酯和胺发生反应,得到具有不同结构的不饱和γ-和ε-氨基酸衍生物。在该方法中,重氮化合物很容易转化为杂化α-酯烷基钯自由基并释放二氮。自由基中间体选择性地加成到 1,3-二烯或丙二烯的双键上,然后是烯丙基钯自由基-极性交叉路径和与胺底物的选择性烯丙基取代,从而产生单个不饱和 γ- 或 ε-氨基酸衍生物。该方法在温和且简单的反应条件下进行,并显示出较高的官能团耐受性,特别是在各种生物活性分子的掺入方面。对放大反应和多种衍生化的研究突出了这种多组分反应方案的实用性。 Beilstein J.

    been produced in good yields, and the X-ray crystal structure of each dirhodium(II) compound has been obtained. The incorporation of additional stereocenters into the dirhodium(II) ligands leads to recognizable levels of double asymmetric induction for C−H insertion, cyclopropanation, and hetero-Diels−Alder cycloaddition applications. The configurationally “matched” cases provide modest increases in enantioselectivity

  • Stereoselectivity in metal carbene and Lewis acid-catalyzed reactions from diastereomeric dirhodium(II) carboxamidates: Menthyl N-acetyl-2-oxoimidazolidine-4(S)-carboxylates
    作者:Michael P. Doyle、John P. Morgan、John T. Colyer
    DOI:10.1016/j.jorganchem.2005.05.032
    日期:2005.12
    The influence of a chiral menthyl group as the pendant ester substituent on the N-acetyl-2-oxoimidazolidine-4S-carboxylate ligands in chiral dirhodium(II) imidazolidinone catalysts has been examined. Significant match/mismatch influences are evident in the observed stereocontrol for carbon-hydrogen insertion reactions with diazoacetates, but these effects are minimal in cyclopropanation reactions. Steric restrictions prevent effective enantiocontrol in hetero-Diels-Alder reactions using these menthyl-substituted catalysts. (c) 2005 Elsevier B.V. All rights reserved.
