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 CHactivation, displayed broad substrate scope with wide functional group compatibility; thus rendering a straightforward entry to a wide variety of N‐heterocycles such as d
