Source of material
The title compound was obtained according to the literature method of preparation of 8,9-dimethoxy-2-nitro-3-(2,4,5-trifluorophenyl)-3H-naphtho[2,1-b]pyran from 1,2,4-trifluoro-5-[(1E)-2-nitroethenyl]-benzene and 2-hydroxy-6,7-dimethoxy-1-naphthalenecarboxaldehyde [1], [2], [3], [4]. A mixture of 2-nitroethenylnaphthalene (1.99 g, 10 mmol), o-hydroxybenzaldohyde (3.66 g, 30 mmol) and 1,4-diazabicyclo[2.2.2]octane (2.44 g, 2 mmol) dissolved in dry THF (30 mL) was refluxed for 3 hr, and then THF was evaporated, the residues were directly charged on a chromatography column to give the pure product 1.42 g (80.5%). Colourless crystals were obtained by slow evaporation of mixed solution of dichloromethane and ethanol (volume 1:1) at room temperature.
Experimental details
Hydrogen atoms were placed geometrically and refined using a riding model with d(C—H) = 0.93–0.98 Å, Uiso(H) = 1.2 Ueq(C) for CH groups. The element of pseudo symmetry in the tiltle structure is a translation along the crystallographic b direction. Generally reflections hkl with k = odd are weaker than those with k = even. All over the structure the translational pseudosymmetry fit is 86% according to the CheckCif program.
Discussion
The 3-nitrochromenes were reported to have pharmaceutically interesting properties, such as anti-breast cancer agents [5], antifungal activity [6], flavodoxin inhibitors against helicobacter pylori infection [7], radioprotective activity [8] and so on. There are two crystallographically independent molecules in the asymmetric unit of the title structure (cf. the figure). They show pseudo-translational symmetry as discussed before [9]. Bond lengths and angels are all in the expected ranges. The dieder angles of O3-C11-C1-C10 is 75°, while the O6-C30-C20-C29 is 110°. The bond angle of C11–C12–C13 is 124.39(13)°, but the C30-C31-C32 is 123.48(13)°.
