  • Construction of contiguous chiral tertiary carbon centers by enantioselective Michael reaction of ketone lithium enolates using a chiral amine ligand
    作者:Kōsuke Yasuda、Mitsuru Shindo、Kenji Koga
    DOI:10.1016/s0040-4039(97)00695-3
    日期:1997.5
    The diastereo- and enantioselective Michael reaction of ketone lithium enolates using a chiral amine ligand (1) was examined. Michael adducts (4) were obtained in excellent chemical yields (95∼99%) with high stereoselectivities (; ee of anti-4: 81∼99%) by the reaction between alkyl phenyl ketones (2) and Michael acceptors (3) having an alkylidene group.
    使用手性胺配体(1)研究了酮烯酸锂的非对映和对映选择性Michael反应。通过烷基苯基酮(2)与迈克尔受体(3)之间的反应,可以以优异的化学收率(95〜99%)获得具有高立体选择性的Michael加合物(4的ee:81〜99 %)。亚烷基。
  • Synthesis of optically active forms of faranal, the trail pheromone of pharaoh's ant
    作者:Kenji Mori、Hiraki Ueda
    DOI:10.1016/0040-4039(81)80126-8
    日期:1981.1
    (3S 4R)-(+)-Faranal and its antipode were synthesized. The former was comparable in bioactivity with that of the natural pheromone.
    合成了(3S 4R)-(+)-芳烃及其对映体。前者的生物活性与天然信息素相当。
  • Palladium- and Copper-Catalyzed 1,4-Additions of Organozinc Compounds to Conjugated Aldehydes
    作者:James A. Marshall、Martin Herold、Hilary S. Eidam、Patrick Eidam
    DOI:10.1021/ol062154a
    日期:2006.11.1
    Conjugated aldehydes undergo smooth Pd(OAc)(2)center dot PPh3- or Me2CuCNLi2-catalyzed 1,4-addition of dialkylzinc reagents.

  • Acyclic diastereocontrol and asymmetric transmission via anionic oxy-Cope rearrangement. Synthesis of key precursors of (+)-faranal and (−)-antirhine
    作者:Shih-Yi Wei、Katsuhiko Tomooka、Takeshi Nakai
    DOI:10.1016/s0040-4020(01)86283-9
    日期:1993.1
    The anionic oxy-Cope rearrangements of acyclic 1,5-dien-3-ols, when their stereochemistries are properly designated. are shown to proceed with a high level of diastereoselection and asymmetric transmission. The utility of the acyclic oxy-Cope variants is demonstrated by the stereocontrolled synthesis of the key precursors of (+)-faranal (insect pheromone) and (-)-antirhine (Corynanthe-type indole alkaloid).
