  • A gold-catalyzed alkyne-diol cycloisomerization for the synthesis of oxygenated 5,5-spiroketals
    作者:Sami F Tlais、Gregory B Dudley
    DOI:10.3762/bjoc.7.66
    日期:——

    A highly efficient synthesis of oxygenated 5,5-spiroketals was performed towards the synthesis of the cephalosporolides. Gold(I) chloride in methanol induced the cycloisomerization of a protected alkyne triol with concomitant deprotection to give a strategically hydroxylated 5,5-spiroketal, despite the potential for regiochemical complications and elimination to furan. Other late transition metal Lewis acids were less effective. The use of methanol as solvent helped suppress the formation of the undesired furan by-product. This study provides yet another example of the advantages of gold catalysis in the activation of alkyne π-systems.

    一种高效合成含氧5,5-螺环缩酮的方法被用于头孢菌素类化合物的合成。在甲醇中,氯化金(I)诱导了一种受保护的炔三醇的环异构化反应,并伴随去保护作用,形成了一种具有战略性羟基化的5,5-螺环缩酮,尽管可能存在区域化学复杂性和生成呋喃的可能性。其他晚期过渡金属Lewis酸的效果较差。甲醇作为溶剂有助于抑制不良呋喃副产物的生成。这项研究提供了另一个金催化在激活炔π-体系中的优势的例子。
  • Stereocontrol of 5,5-Spiroketals in the Synthesis of Cephalosporolide H Epimers
    作者:Sami F. Tlais、Gregory B. Dudley
    DOI:10.1021/ol102201z
    日期:2010.10.15
    A blueprint for controlling the stereochemistry of oxygenated 5,5-spiroketals using chelation effects is provided. Chelation specifically of zinc salts (other protic and Lewis acids were less effective) between the spiroketal oxygen and an appropriately positioned alcohol group overrides normal biases in the preparation of 5,5-spiroketals, as illustrated by the stereocontrolled synthesis of epimeric cephalosporolide H isomers. This study provides new and valuable information for prescribing the chirality of the stereogenic core of 5,5-spiroketals.
  • On the proposed structures and stereocontrolled synthesis of the cephalosporolides
    作者:Sami F Tlais、Gregory B Dudley
    DOI:10.3762/bjoc.8.146
    日期:——
    The synthesis of four candidate stereoisomers of cephalosporolide H is described, made possible by a zinc-chelation strategy for controlling the stereochemistry of oxygenated 5,5-spiroketals. The same strategy likewise enables the first stereocontrolled synthesis of cephalosporolide E, which is typically isolated and prepared admixed with its spiroketal epimer, cephalosporolide F.
    描述了头孢菌素 H 的四种候选立体异构体的合成,通过锌螯合策略控制氧化 5,5-spiroketals 的立体化学成为可能。同样的策略同样使头孢菌素 E 的首次立体控制合成成为可能,它通常是分离出来的,并与其螺缩酮差向异构体头孢菌素 F 混合制备。
