cascade approach for the synthesis of meta‐N,N‐diarylaminophenols (DAAP) starting from exocyclic β‐enaminones has been developed. The feasibility of the process is rationalized by the suitable molecular geometry of β‐enaminones for tandem N‐arylative α‐iodination and aromatization under milder basic conditions. Furthermore, the developed strategy has been extended to the synthesis of meta‐N‐benzyl‐N‐arylaminophenols
