Concise and efficient N-arylation-based domino [3+2] heterocyclization promoted by p-TsOH has been established for the synthesis of 27 examples of 3-arylamino substitutedfusedpyrrole derivatives in 70–90% yields. The present methodology shows attractive properties, such as mild reaction conditions, concise one-pot operation, short reaction periods of 15–30 min, and easy purification. It can avoid
