dioxinone-derived silyl ether to nitroalkenes is reported. The conjugate addition is performed in absence of any catalyst under solvent-free conditions, proceeding with satisfactory efficiency with variously substituted nitroalkenes.Moreover, the first organocatalyzed Mukaiyama-Michael vinylogous reaction of trimethylsilyloxyfuran to nitroalkenes is described.The reaction is promoted by Brønsted acids under
报道了二恶英衍生的甲硅烷基醚与硝基烯烃的第一次 Mukaiyama-Michael 乙烯系反应。共轭加成是在无溶剂条件下在没有任何催化剂的情况下进行的,与各种取代的硝基烯烃以令人满意的效率进行。此外,描述了三甲基甲硅烷氧基呋喃到硝基烯烃的第一个有机催化的 Mukaiyama-Michael 乙烯基反应。该反应由布朗斯台德酸促进在无溶剂条件下,使用各种取代的硝基烯烃以中等至良好的收率进行。
