  • Total Synthesis of (±)-Gephyrotoxin by Amide-Selective Reductive Nucleophilic Addition
    作者:Kenji Shirokane、Takamasa Wada、Makoto Yoritate、Ryo Minamikawa、Nobuaki Takayama、Takaaki Sato、Noritaka Chida
    DOI:10.1002/anie.201308905
    日期:2014.1.7
    the total synthesis of (±)‐gephyrotoxin has been developed. The key to success was the utilization of N‐methoxyamides, which enabled the direct coupling of the amide with an aldehyde and selective reductive nucleophilic addition to the amide in the presence of a variety of sensitive and electrophilic functional groups, such as a methyl ester. This chemoselective approach minimized the use of protecting‐group
    已开发出一种化学选择性的方法,可以完全合成(±)-地理毒素。成功的关键是利用N-甲氧基酰胺,它可以使酰胺与醛直接偶联,并在存在各种敏感和亲电子官能团(例如甲酯)的情况下,将酰胺选择性还原性亲核加成到酰胺上。这种化学选择性方法最大程度地减少了保护基操纵和氧化还原反应的使用,从而实现了迄今为止描述的最简洁,最有效的(±)-地球毒毒素的全合成。

  • Total synthesis of (.+-.)-gephyrotoxin
    作者:Roger Fujimoto、Yoshito Kishi、John F. Blount

    日期:1980.11
    numerous synthetic studies. Total syntheses have been reported by Kishi, Hart, Overman, as well as Sato and Chida, and a number of formal syntheses have been described. Smith and co-workers now report an elegant and concise synthesis of gephyrotoxin that relies on an intramolecular enamine/Michael cascade to access the tricyclic scaffold of the natural product. Comment: The synthesis commenced with L-pyroglutaminol
    意义:Gephyrotoxin 是一种相对无毒的 dendrobatid 生物碱,具有不寻常的神经学特征。它的特性和复杂的结构使其成为众多合成研究的主题。Kishi、Hart、Overman 以及 Sato 和 Chida 已经报道了全合成,并且已经描述了许多正式的合成。Smith 及其同事现在报告了一种优雅简洁的 gephyrotoxin 合成方法,该合成方法依赖于分子内烯胺/迈克尔级联反应来获取天然产物的三环支架。评论:合成从 L-焦谷氨酰胺 (A) 开始,通过五个简单的步骤将其转化为关键中间体 F。通过用 TFA 处理实现 F 的脱保护,并在氯仿中加热至 40 °C 导致形成亚胺盐 H,其依次进行羟基定向还原以 79% 的产率得到 I。一些官能团相互转化然后导致 K。与炔烃 L 交叉偶联,然后去保护提供合成 gephyrotoxin。H
