An efficient synthesis of a variety of trans-2,3-dihydropyrroles via iodine-promoted cyclization between chalcones and enaminones has been demonstrated under liquid-assisted grinding conditions. The present protocol provides a practical, fast and green alternative to traditional solvent-based methods due to its notable advantages such as significantly higher yield, much shorter reaction time, good functional group tolerance and mild reaction conditions.
