A Cu-catalyzed asymmetric kinetic boron conjugate addition of γ-substituted α,β-unsaturated γ-lactams followed by oxidation is reported with good results. This strategy provides an efficient access to valuable enantioenriched α,β-unsaturated γ-lactams bearing simple γ-alkyl or aryl substituents, which showed inhibitory activities against cisplatin-sensitive ovarian cancer cells A2780.

据报道,Cu 催化的 γ-取代的 α,β-不饱和 γ-内酰胺的不对称动态硼共轭加成反应随后进行氧化,取得了良好的结果。该策略提供了一种有效获得有价值的对映体富集的α,β-不饱和γ-内酰胺的途径,该内酰胺带有简单的γ-烷基或芳基取代基,其对顺铂敏感的卵巢癌细胞A2780表现出抑制活性。提出了一种新的路易斯酸铜催化机理。
