reaction provides an efficient route to α‐ketoamides compounds, which are ubiquitous structural units in a number of biologically active compounds. N‐substituted anilines are suitable substrates for this transformation. Two CH bonds as well as one CH and one NH bond are cleaved in this reaction. Molecular oxygen (1 atm) is used as the oxidant and the reaction involves dioxygen activation.
高效实用:标题反应为α-酮酰胺化合物提供了一条有效途径,α-酮酰胺化合物是许多生物活性化合物中普遍存在的结构单元。N-取代的苯胺是该转化的合适底物。两个C H键以及一种C H和一个N- H键被裂解在该反应中。分子氧(1个大气压)用作氧化剂,反应涉及双氧活化。
