    Diastereoselective Friedel–Crafts Alkylation of Hydronaphthalenes
    摘要:
    An efficient and versatile synthesis of chiral tetralins has been developed using both inter- and intra-molecular Friedel Crafts alkylation as a key step. The readily available hydronaphthalene substrates were prepared via a highly enantioselective metal-catalyzed ring opening of meso-oxabicyclic alkenes followed by hydrogenation. A wide variety of complex tetracyclic compounds have been isolated with high levels of regio-, diastereo-, and enantioselectivity.

  • Fesulphos-Palladium(II) Complexes as Well-Defined Catalysts for Enantioselective Ring Opening of Meso Heterobicyclic Alkenes with Organozinc Reagents
    作者:Silvia Cabrera、Ramón Gómez Arrayás、Inés Alonso、Juan C. Carretero
    DOI:10.1021/ja055692b
    日期:2005.12.1
    The air-stable and readily available cationic methyl palladium(II) complexes of planar chiral Fesulphos ligands [(Fesulphos)Pd(Me)(PhCN)]+ X- are highly efficient catalysts for the alkylative ring opening of oxa- and azabicyclic alkenes with dialkylzinc reagents, showing broad scope with regards to both the bicyclic substrate and the dialkylzinc reagent. Catalyst loading as low as 0.5 mol % is sufficient

    日期:——
    A new nickel-catalyzed syn-stereocontrolled ring-opening of oxa- and azabicyclic alkenes with dialkylzinc reagents was developed, which afforded the corresponding cis-2-alkyl-1,2-dihydronaphthalen-1-ols and 1,2-alkyl amide derivatives in moderate to excellent yields (up to 99% yield) under mild conditions. In this work, we successfully avoided obtaining hydride addition byproducts arising from β-hydride
    用二烷基锌试剂开发了一种新的镍催化的氧杂-和氮杂双环烯烃的顺式立体控制开环反应,得到相应的顺式-2-烷基-1,2-二氢萘-1-醇和1,2-烷基酰胺衍生物在温和的条件下,以中等至优异的产量(高达99%的产量)。在这项工作中,我们成功地避免了由于在乙基镍物质上消除β-氢化物而产生的氢化物加成副产物。此外,还提出了一种可能的开环反应机理。
  • Mechanistic Studies of the Palladium-Catalyzed Ring Opening of Oxabicyclic Alkenes with Dialkylzinc
    作者:Mark Lautens、Sheldon Hiebert、Jean-Luc Renaud
    DOI:10.1021/ja010498k
    日期:2001.7.1
    The mechanism of the palladium-catalyzed ring opening of oxabicyclic alkenes with dialkylzinc has been studied. Experiments which rule out a π-allyl mechanism were carried out. Trapping carbometalated products and synthesis and successful reaction of alkyl palladium species provided strong evidence in favor of an enantioselective carbopalladation as the key step in the mechanism. The studies also suggest
    研究了钯催化氧化二环烯烃与二烷基锌的开环机理。进行了排除π-烯丙基机制的实验。捕获碳金属化产物以及烷基钯物种的合成和成功反应为支持对映选择性碳钯化作为该机制的关键步骤提供了强有力的证据。研究还表明,阳离子钯物种负责烯烃的碳钯化。钯和二烷基锌的组合是独特的,因为二烷基锌在金属转移中起到钯的作用,并且在形成反应性阳离子钯物质时作为路易斯酸起作用。

This new procedure proved to
