Yb(OTf)(3) with TMSCl or TMSOTf catalyzed an imino ene reaction. The reaction of N-tosylbenzaldimine (1) with alpha-methylstyrene (2) proceeded smoothly to give homoallylic amine 3 in the presence of a catalytic amount of Yb(OTf)(3) and TMSCl. This catalytic system was successfully applied to the imino ene reactions of various aldimines with alkenes. This new imino ene reaction provides a unique method for
Yb(OTf)(3)与TMSC1或TMSOTf的新型组合系统催化亚氨基反应。在催化量的Yb(OTf)(3)和TMCSI存在下,N-甲苯磺酰基苯甲二胺(1)与α-甲基苯乙烯(2)的反应平稳进行,得到均烯丙基胺3。该催化体系已成功地用于各种醛亚胺与烯烃的亚氨基反应。这种新的亚氨基烯反应为在Yb(OTf)(3)和TMSOTf存在下醛,甲苯磺酰胺和α-甲基苯乙烯的三组分偶联反应提供了一种独特的方法,以得到相应的均烯丙基胺。
