  • Convergent synthesis of 2H-chromenes—a formal [3+3] cycloaddition by a one-pot, three-step cascade
    作者:Kathlyn A. Parker、Thomas L. Mindt
    DOI:10.1016/j.tet.2011.09.068
    日期:2011.12
    In cases in which the palladium-catalyzed coupling of a bromoquinone with a vinyl stannane affords a vinyl quinone that enolizes, the resulting ortho-quinone methide undergoes an oxa-6 pi electrocyclization. Enolization is promoted by the presence of a polar additive. The net conversion is a formal [3+3] cycloaddition that gives 2H-chromenes. Because the first two steps of the cascade are catalyzed, the overall conversion is an example of multicatalysis. Yields for the optimized, one-pot protocol are dramatically improved over the conventional stepwise process. (C) 2011 Elsevier Ltd. All rights reserved.
  • Electrocyclic Ring Closure of the Enols of Vinyl Quinones. A <i>2H</i>-Chromene Synthesis
    作者:Kathlyn A. Parker、Thomas L. Mindt
    DOI:10.1021/ol0167199
    日期:2001.11.1
    Thermolysis of enolizable vinyl quinones in polar, aprotic media provides 2H-chromenes. Experimental evidence supports a two-step mechanism in which enolization is followed by a thermal 6pi-electrocyclic reaction of an intermediate quinone methide. Application of this method led to the total synthesis of the reputed structure of an Ageratum juvenile hormone. When enolizable vinyl quinones are the products
    极性非质子介质中可烯化的乙烯基醌的热解可提供2H-色烯。实验证据支持两步机理,其中烯醇化之后是中间体醌甲基化物的热6π-电环反应。该方法的应用导致了香ger子幼体激素的已知结构的全合成。当可烯化的乙烯基醌是斯蒂勒偶联的产物时,可直接获得色烯环化产物。[反应:看文字]
