A simple two-step sequence for the synthesis of novel 4-aryl-4,5-dihydro- 6H-[1,3]dioxolo[4,5-h]pyrrolo[1,2-a][1]benzazepin-6-ones from 6-amino-3,4-methylenedioxyacetophenone

Herein is provided an efficient and two-step short procedure for the synthesis of novel 6H-[1,3]dioxolobenzo[4,5-h]pyrrolo[1,2-a][1]benzazepin-6-one derivatives promoted by commercial phosphoric acid. In a parallel approach some pyrrolyl chalcones were isolated that proved to behave as intermediates for the title compounds. Wiley-VCH Verlag GmbH & Co. KGaA, 2008.
