The synthesis of 2-carbonylindoles was achieved via a iodine-mediated cyclization of the corresponding enaminone precursors, which were form ed by reaction of the α-arylaminomethylene carbonyl derivatives with N,N′-dimethylformamide dimethyl acetal (DMFDMA). An alternative and more efficient procedure consisted of a similar cyclization of the enaminones, but under solvent-free and grinding reaction

A new approach is described for the synthesis of substi- tuted indoles 5, through an intramolecular and regioselective Friedel-Crafts cyclization of enaminones 6a-h catalyzed by Lewis acids. Compounds 6 were prepared from the 2-anilinocarbonyl compounds 7, by treatment with DMFDMA under thermal or mi- crowave (MW) irradiation conditions. An alternative and shorter one-pot two-step synthesis of indoles

However, successful clinical cases of nitrone therapeutics are still lacking. Herein we report the synthesis and antiproliferative activity of a series of structurally diverse nitrone derivatives against a panel of 5 cancer cell lines, based on which indole- and pyrrole-fused were further evaluated by analogue preparation and in-vitro screening. Analogues with moderate to good potency were identified
