  Comparison of the reaction pathways and intermediate products of a microwave-assisted and high-pressure-promoted cycloaddition of vinyl-moiety-containing dienophiles on 2H-pyran-2-ones

  摘要：

  A comparative study of the reaction pathway of the cycloaddition of various vinyl-containing dienophiles on a set of substituted 3-acylamino-2H-pyran-2-ones under microwave-assisted and high-pressure conditions is presented. In the course of the reaction both the intermediate products, i.e., the 2-oxabicyclo[2.2.2]oct-5-ene (the exo/endo selectivity depended upon the dienophile) and the alkoxycyclohexadiene systems, were isolated and comprehensively characterized; this included X-ray diffraction analyses. The role of the base (DABCO) as an organocatalyst was further elucidated. (C) 2011 Elsevier Ltd. All rights reserved.

  We present a study of the Diels-Alder reaction between various electron-deficient 2H-pyran-2-ones and ethyl vinyl ether. This microwave-accelerated sequence of a cycloaddition followed by a retro-Diels-Alder reaction (the elimination of CO 2 ) and a second elimination step ofEtOH yields substituted aniline derivatives. The reaction sequence is greatly accelerated by the application of DABCO as a suitable

  我们研究了各种缺电子 2H-pyran-2-ones 与乙基乙烯基醚之间的 Diels-Alder 反应。这种微波加速的环加成顺序，随后是逆狄尔斯-阿尔德反应（CO 2 的消除）和EtOH的第二个消除步骤，产生取代的苯胺衍生物。使用 DABCO 作为合适的碱大大加快了反应顺序。
