1,2-arylmethylation cascades of N-(arylsulfonyl)acrylamides for the assembly of 2,2-disubstituted-N-arylbutanamides containing an all-carbon quaternary center is presented. This reaction enables the one-step formation of two new C–C bonds through a sequence of methylation/1,4-aryl migration/desulfonylation using an organic peroxide as the methyl resource with a broad substrate scope and excellent functional
提出了一种新的,无金属的N-(芳基磺酰基)丙烯酰胺氧化1,2-芳基甲基化级联反应,用于组装含全碳季中心的2,2-二取代的N-芳基丁酰胺。该反应通过使用有机过氧化物作为甲基资源,具有广泛的底物范围和出色的官能团耐受性,通过一系列甲基化/ 1,4-芳基迁移/脱磺酰基反应,可以一步一步形成两个新的C–C键。
