Yb(OTf)3 and Tb(OTf)3 to give the desired β-aminonitriles, β-amino sulfones, and dimethyl aspartates, respectively, in moderate to excellent yields. The reactions were carried out in toluene for Yb(OTf)3 and in t-BuOMe for Tb(OTf)3, all reactions were performed at 100 °C.
使用 Yb(OTf) 3和 Tb(OTf) 3独立催化的芳基胺实现丙烯腈、苯基乙烯基砜和马来酸二甲酯的迈克尔型氢胺化,分别得到所需的 β-氨基腈、β-氨基砜和天冬氨酸二甲酯,中等至优异的产量。 Yb(OTf) 3 的反应在甲苯中进行, Tb(OTf) 3 的反应在t -BuOMe中进行,所有反应均在100℃下进行。
