  • A Formal Asymmetric Synthesis of Calabar Bean Alkaloids.
    作者:Manabu NODE、Xiao-jiang HAO、Kiyoharu NISHIDE、Kaoru FUJI
    DOI:10.1248/cpb.44.715
    日期:——
    A total synthesis of (-)-eserethole (2) has been accomplished using the Diels-Alder reaction of (S)-(-)-2-methyl-2-[2-(E)-nitroethenyl]-δ-valerolactone (3) and Danishefsky's diene as a key step. The synthesis of optically pure (-)-eserethole (2) constitutes a formal synthesis of naturaly occurring Calabar bean alkaloids, such as (-)-physostigmine (1), (-)-physovenine (17) and (-)-geneserine (18).
    (-)-eserethole (2) 的全合成已经完成,其中关键步骤是利用(S)-(-)-2-甲基-2-[2-(E)-硝基乙烯基]-δ-戊内酯(3)与Danishefsky's二烯的Diels-Alder反应。光学纯(-)-eserethole (2)的合成构成了卡拉巴豆生物碱如(-)-physostigmine (1)、(-)-physovenine (17)和(-)-geneserine (18)的形式合成。
  • General entry to the synthesis of optically active diterpenoids of C-20β series

  • An efficient asymmetric synthesis of nitroolefinic lactones with chiral nitroenamines possessing bulky chiral leaving groups
    作者:Xiaowu Yang、Rui Wang
    DOI:10.1016/s0957-4166(97)00452-7
    日期:1997.10
    An efficient asymmetric nitroolefination of enolates 4a-c, 5 afforded multifunctional group nitroolefinic lactones 7a-e and 8a,b containing stereogenic quaternary carbon centers using bulky chiral nitroenamines 1a,b–3a,b as chiral auxiliaries. Studies on the effect of the bulkiness of leaving group showed that bulky nitroenamines 1a,b gave higher ees and yields than those of the less bulky 2a,b–3a
    有效的烯醇盐4a-c,5的不对称硝基烯烃化反应,使用了庞大的手性亚硝胺1a,b-3a,b作为手性助剂,从而得到了多官能团的硝基烯烃内酯7a-e和8a,b,其中含有立体生成的季碳中心。研究的离去基团的体积的效果表明,笨重nitroenamines 1A,B,得到更高EES和产量比那些不太笨重的图2a,2b-3A,3B。提出了一种可能的循环跃迁模型,以阐明S的选择性。
  • Enhanced Reactivity of Zinc Enolates over Lithium Enolates in Asymmetric Nitroolefination.

    DOI:10.1248/cpb.42.999
    日期:——
    Zinc enolates derived from an ester and a lactone, 1 and 4, were found to have enhanced reactivity over the corresponding lithium enolates in asymmetric nitroolefination.
    研究发现,在不对称硝基油化反应中,由酯和内酯衍生的烯醇化锌 1 和 4 比相应的烯醇化锂具有更强的反应活性。
  • An Asymmetric Nitroolefination of α-Alkyl-γ-and δ-Lactones with Modified Nitroenamines
    作者:Kiyoharu Nishide、Ryuichi Kurosaki、Kouichi Hosomi、Hitoshi Imazato、Takehisa Inoue、Manabu Node、Toshiumi Ohmori、Kaoru Fuji
    DOI:10.1016/0040-4020(95)00683-y
    日期:1995.10
    New chiral nitroenamines 4a,b having (S)-2-t-butyldimethylsiloxymethylpyrrolidine as an auxiliary were found to be very effective for asymmetric nitroolefination of alpha-alkyl-gamma- and delta-lactones. The enantiomeric excess of the product increased remarkably in the reaction with gamma-lactones compared with previous nitroenamines 1a,b. A possible chelation model for the transition state of the asymmetric nitroolefination is discussed.
