A mild, green, and facile method for the synthesis of 2,3,3a,4‐tetrahydropyrrolo[1,2‐a]quinazoline‐1,5‐dione derivatives is described in high yields by using ionic liquids as green media. The method involves the reaction of 2‐aminobenzamides with 4‐oxopentanoic acid or 4‐aryl‐4‐oxo‐butanoic acid catalyzed by iodine and has the advantages of mild reaction conditions, high yields, one‐pot, operational
