AbstractAn operationally simple and efficient protocol for squaric acid catalyzed synthesis of N-substituted pyrroles via the reaction of 2,5-dimethoxytetrahydrofuran and 2,5-hexandione with aryl amines in green reaction media (water, deep eutectic solvent, and polyethylene glycol) under ultrasound irradiation or thermal conditions in good to excellent yields has been developed.
