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, 69451 Weinheim, Germany, 2008)
