The molecular-electronic structure and supramolecular aggregation in 1-(6-amino-1,3-benzodioxol-5-yl)-3-arylprop-2-en-1-ones was investigated. The molecules of (I) were linked into simple sheets generated by translation, by means of one N-H...O and one C-H...π(arene) hydrogen bond. Compounds (I) and (II) crystallized with Z' values of 1 and 2 while compound (II) formed two polymorphs which were monoclinic and triclinic denoted as (IIa) and (IIb). It was observed that the monoclinic polymorph had a higher density than the triclinic polymorph and was thermodynamically more stable form.
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.
