  Concurrent construction of five and six membered fused N-heretocyclic ring was achieved via a conceptually new three-component reaction affording 6,6a-dihydroisoindolo[2,1-a]quinazoline-5,11-diones as novel inhibitors of TNF-alphain vitro. This represents one of the few examples of direct TNF-alpha inhibition by small molecules.

  A mild, green, and facile method for the synthesis of 6,6a‐dihydroisoindolo[2,1‐a]quinazoline‐5,11‐dione derivatives is described in high yields using ionic liquids as green media. The method involves the reaction of 2‐aminobenzamides with 2‐formylbenzoic acid catalyzed by iodine and provides a new alkaloid library with potential activity for biomedical screening.
