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 ionicliquids 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.

Abstract A green procedure for the rapid diversification of quinazolin-4-(1H)-one scaffolds is described in this paper. Various types of 1,2-dicarbonyl compounds are treated with 2-aminobenzamides in ionicliquidscatalyzed by iodine and unexpectedly afford structurally diversified single-quinazoline derivatives. The recyclability of the ionicliquids makes this protocol to be an environmentally benign
