A new class of rhodium-catalyzed, C–H activation triggered [3 + 2] annulations of aromatic aldimines or ketimines and maleimides was reported in this study. A broad scope of general imines without electron-withdrawing groups were successfully activated and could effectively react with N-substituted maleimide to afford pericyclic, multichiral centered amines in good yields and with excellent diastereoselectivity
这项研究报道了一种新型的铑催化的C–H活化引发[3 + 2]芳族醛亚胺或酮亚胺和马来酰亚胺的环化反应。广泛范围的不带吸电子基团的一般亚胺被成功活化,可以与N-取代的马来酰亚胺有效反应,以良好的收率和优异的非对映选择性提供周环,多手性中心胺。
