The reaction of olefins with malonamide in the presence of manganese(III) acetate gave 2-buten-4-olides and/or 1H-pyrrol-2(5H)-ones in one-step, short reaction time, and moderate yields. The product distribution can be accounted for in terms of the stabilization of the intermediate carbocation in the oxidation process. The synthetic application and limitation, and the oxidation mechanism for the formations
在乙酸锰 (III) 存在下,烯烃与丙二酰胺反应可一步生成 2-buten-4-olides 和/或 1H-pyrrol-2(5H)-ones,反应时间短,产率适中。产物分布可以根据氧化过程中中间碳正离子的稳定性来解释。讨论了α,β-不饱和γ-内酯和γ-内酰胺的合成应用和局限性,以及氧化机制。
