addition reaction of N‐Ts‐2‐arylanilines with activated olefins has been achieved at ambient temperature under the newly defined reaction conditions. This process highlighted the directing effect of the N‐protecting group in CH activation, displayed broad substrate scope with wide functional group compatibility; thus rendering a straightforward entry to a wide variety of N‐heterocycles such as d
简便高效:在新定义的反应条件下,在环境温度下实现了N -Ts-2-芳基苯胺与活化烯烃的Pd催化多米诺烯化反应/共轭加成反应。该过程突出了N保护基在CH活化中的指导作用,显示了广泛的底物范围和广泛的官能团相容性。因此可以直接进入各种N杂环化合物,例如二氢菲啶。
