An efficient method for the acceleration of the intramolecular Diels-Alder reaction was established utilizing the internal interaction—the internal hydrogen bonding and the internal coordination of a magnesium salt. The intramolecular Diels-Alder reaction between nitrofuran derivatives and various acrylic acid derivatives give good yields of the cycloadducts when internal hydrogen bonding is present. When cyclic α,β-unsaturated amides are employed as dienophile, the corresponding cycloadducts are obtained in high yield utilizing internal coordination of a magnesium salt.
利用内部相互作用--内部氢键和镁盐的内部配位,建立了一种加速分子内 Diels-Alder 反应的有效方法。当存在内部氢键时,硝基呋喃衍生物和各种丙烯酸衍生物之间的分子内 Diels-Alder 反应会产生很好的环加成物产率。当使用环状 α、β-不饱和酰胺作为亲二烯时,利用镁盐的内部配位可获得相应的环加载产物,产率很高。
