    紫杉烷和异紫杉烷衍生物的级联复分解反应。
    摘要:
    三环异紫杉烷和紫杉烷衍生物已通过非常有效的级联闭环二烯炔复分解(RCDEYM)反应合成,该反应在一次操作中形成了A和B环。当炔烃存在于C13处(没有相邻的二甲基二甲基)时,RCEDYM反应生成在A环上具有二甲基二甲基的14,15-异紫杉烷16a,b和18b。如果炔烃位于C11位置(并在其旁接有一个二甲基gem基),则RCEDYM反应仅在C13处存在三取代烯烃的情况下进行,这不利于竞争性的二烯闭环易位反应,从而形成三环核紫杉醇44。

  • Highly Efficient Synthesis of the Tricyclic Core of Taxol by Cascade Metathesis
    作者:Aurélien Letort、Rémi Aouzal、Cong Ma、De-Liang Long、Joëlle Prunet
    DOI:10.1021/ol501304j
    日期:2014.6.20
    An efficient enantioselective synthesis of the ABC tricyclic core of the anticancer drug Taxol is reported. The key step of this synthesis is a cascade metathesis reaction, which leads in one operation to the required tricycle if appropriate fine-tuning of the dienyne precursor is performed.

  • An “Aprotic” Tamao Oxidation/<i>Syn</i>-Selective Tautomerization Reaction for the Efficient Synthesis of the C(1)–C(9) Fragment of Fludelone
    作者:Tyler J. Harrison、Philippe M. A. Rabbat、James L. Leighton
    DOI:10.1021/ol302221s
    日期:2012.9.21
    An efficient synthesis of the C(1)–C(9) fragment of fludelone has been developed. The key step is a tandem silylformylation–crotylsilylation/Tamao oxidation sequence that establishes the C(5) ketone, the C(6), C(7), and C(8) stereocenters, and the C(9) alkene in a single operation from a readily accessed starting material. The stereochemical outcome at C(6) depends critically on the development of
