through the 1,6-Michael addition. The synthetic utility of furan is further explored. These precursors are easily accessible from aryl methyl ketones. Various functional groups like alkyl, aryl, nitrile, amine, aroyl, and thiomethyl can be directly installed in the benzene and furan rings. A one-pot approach for the construction of a benzene nucleus was also developed. The structure of two compounds
我们描述了空间位阻对 2-(3,3-双(甲硫基)-1-芳基烯丙基)丙二腈的 1,4-与1,6-迈克尔加成反应的影响。通过 2-(3,3-双(甲硫基)-1-芳基烯丙基)丙二腈和丙酮在温和条件下通过 1,4-Michael 加成反应实现了三取代呋喃的高效直接合成,收率良好至中等。进一步探索与含有 2-(3,3-双(甲硫基)-1-芳基烯丙基)丙二腈的空间位阻芳基的反应,通过原位生成的亲核试剂通过 1,6-迈克尔加成提供联芳基。进一步探索了呋喃的合成用途。这些前体很容易从芳基甲基酮中获得。各种官能团如烷基、芳基、腈、胺、芳酰基和硫甲基可以直接安装在苯环和呋喃环上。还开发了一种构建苯核的一锅法。通过X射线晶体学证实了两种化合物的结构。
