cascade C−N, C−C and C−O multiple‐bond‐formation reaction to synthesize 3‐acylindoles from 2‐alkenylanilines with DMF (N,N‐dimethylformamide) as a one‐carbon synthon is described. This approach employed dioxygen as a terminal oxidant and oxygen donor, generally provided the 3‐acylindoles in moderate to good yields. Moreover, the mechanistic investigation unambiguously revealed that the 2‐carbon of 3‐acylindole
描述了一种级联的C,C和C的多键形成反应,以2烯基苯胺与DMF(N,N-二甲基甲酰胺)作为单碳合成子合成3-酰基环。该方法采用双氧作为末端氧化剂和氧供体,通常以中等至良好的产率提供3-酰基环。此外,机理研究清楚地表明,3-丙烯腈的2-碳源自DMF的N-甲基。
