In the title compound (systematic name: 9-eth­oxy-10-meth­oxy-5,6-dihydro-1,3-dioxolo[4,5-g]isoquinolino­[3,2-a]isoquin­olin-7-ium iodide monohydrate), 2C21H20NO4+·2I·H2O, two independent mol­ecules pack in the unit cell, where interactions between the molecules are stabilized by weak inter­molecular π–π stacking inter­actions [centroid–centroid distances in the range 3.571 (4) to 3.815 (4)Å]. Inter­molecular C—H...O inter­actions are also observed. The iodide anions are disordered with occupancy ratios of 0.94 (1):0.06 (1) and 0.91 (1):0.09 (1). The cationic molecule is planar in structure with a small torsion resulting from the dihydropyridine ring.

Comment top

The title compound, a derivative of the natural product berberine, is of interest with respect to its anti-parasite activity and biological properties Chen et al. (2009). Of particular interest is the discovery that berberine and its analogs inhibit the growth of strains of the parasites Leishmania (Nkwengoua et al., 2009, Acero et al., 1995, Ghosh et al., 1985), Trypanosoma (Nkwengoua et al., 2009), and Plasmodium (Wright et al., 2000, Iwasa et al., 1998, Sheng et al., 1997, McCall et al., 1994). Based on these findings and in our continued effort to characterize compounds that may inhibit the life cycle of the parasite Toxoplasma gondii we have synthesized the 9-ethyl analog of berberine.

The title compound, 2(C21H20NO4+), 2(I-), H2O, crystallizes in the P-1 space group with two independent molecules in the unit cell. A solvent water molecule occupies the lattice at H-bonding distance from the disordered iodide (1.94 & 0.06) anions [O5—I1A 3.509 (6) and O5—I1B 3.600 (6) Å]. The compound crystallizes with a slightly twisted planar structure due to the dihydropyridine moiety, which results in torsion angles of 17.7 (5)° (C15A/C16A/C11A/C2A) and 6.1 (5)° (C15B/C16B/C11B/C2B) between the planes of the isoquiniline and benzodioxole moieties for molecules A and B respectively. The molecules are layered in the crystal lattice with normal ππ stacking distances between centroids of the rings of molecules A and B of 3.571 (4)Å (rings C6A/C7A/C8A/C9A/C15A/C16A to C2B/C11B/C12B/C13B/C14B/C18B), 3.839 (4)Å (rings N1A/C5A/C10A/C15A/C16A/C17A to N1B/C5B/C10B/C15B/C16B/C17B), and 3.686 (4)Å (rings C2A/C11A/C12A/C13A/C14A/C18A to C6B/C7B/C8B/C9B/C15B/C16B). Identical molecules neighboring each other are located at further stacking distances with the closest controid distance of 3.815 (4)Å between molecules A to A and 3.949 (4)Å between molecules B to B.

Experimental top

The title compound was prepared by vacuum pyrolysis of berberine hydrochloride followed by alkylation with ethyl iodide (Iwasa et al., 1997). The crystals suitable for single-crystal X-ray diffraction were grown in DMSO-d6. The crystal was diffracted in the cold stream of an X-Stream 2000 Liquid nitrogen generator with an open-flow nitrogen cryostat with a nominal stability of 0.1 K.

Refinement top

The H atoms were all located in a difference map, but those attached to carbon atoms were repositioned geometrically. The H atoms were initially refined with soft restraints on the bond lengths and angles to regularize their geometry (C—H in the range 0.93–0.98, O—H = 0.82 Å) and Uiso(H) (in the range 1.2–1.5 times Ueq of the parent atom), after which the positions were refined with riding constraints. The ethyl groups on the molecules were found to have some disorder, with the methylene carbon (C20B) demonstrating the largest thermal parameters. The disordered iodide anions were solved with two partially occupied positions. The anisotropic parameters Uxy were restrained for each of the iodide pairs during refinement.
