Source of material
All reagents and chemicals were purchased from commercial sources and used without further purification. Sodium 5-(8-(((5-carboxypentyl)amino)methyl)-7-hydroxy-4-oxo-4H-chromen-3-yl)-2-hydroxybenzenesulfonate was synthesized via a Mannich reaction. In a typical experiment a formaldehyde solution (25 mL, 37%), 6–aminocaproic acid aqueous solution (3.148 g, 6–aminocaproic acid, 0.024 mol, 13 mL water) and sodium 2-hydroxy-5-(7-hydroxy-4-oxo-4H-chromen-3-yl) benzenesulfonate (8.544 g, 0.024 mol) were added to ethanol (450 mL, 99%) and stirred for 36 h at 328 K. After cooling, the volatile solvents were removed under vacuum on a rotatory evaporator at 303 K. Water was added to the remaining liquid and the total volume of mixture was 120 mL. The mixture was heated to 333 K until a transparent solution was obtained. After cooling for 20 min, the mixture was filtered and the residue was washed with water. The residue was dried at 383 K. Sodium 5-(8-(((5-carboxypentyl)amino)methyl)-7-hydroxy-4-oxo-4H-chromen-3-yl)-2-hydroxybenzenesulfonate (1.85 g) was obtained. A mixture of sodium salt described before (0.025 g), sodium nitrite (0.035 g), 6 mol/L nitric acid (0.4 mL) and water (10 mL) was sealed in a 20 mL vial and sonicated for 10 min. The mixture was heated at 363 K for 22 h. Yellow needle crystals of the title compound were obtained. 1H NMR (400 MHz, DMSO-d6) δ: 8.58 (s, 1H, H9), 8.11 (d, J = 2.2 Hz, 1H, H15), 8.07 (d, J = 8.9 Hz, 1H, H3), 8.05 (d, J = 2.2 Hz, 1H, H11), 7.12 (d, J = 8.9 Hz, 1H, H2), 4.30 (s, 2H, H16A, H16B), 3.00 (m, 2H, H17A, H17B), 2.22 (m, 2H, H21A, H21B), 1.65 (m, 2H, H20A, H20B), 1.52 (m, 2H, H18A, H18B), 1.33 (m, 2H, H19A, H19B). 13C NMR (100 MHz, DMSO-d6) δ: 174.46 (C22), 174.29 (C7), 161.70 (C1), 156.00 (C5), 154.18 (C9), 147.57 (C13), 137.80 (C14), 133.44 (C12), 132.28 (C11), 128.27 (C10), 126.65 (C3), 122.14 (C15), 121.25 (C8), 116.43 (C4), 114.64 (C6), 105.75 (C2), 47.04 (C17), 38.57 (C16), 33.42 (C21), 25.55 (C18), 25.10 (C19), 24.05 (C20). IR spectra (potassium bromide pellet) were recorded on a Nicolet 6700. IR (v/cm−1): 3159, 2337, 2026, 1713, 1627, 1537, 1451, 1385, 1311, 1259, 1227, 1197, 1125, 1042, 946, 907, 882, 848, 801, 769, 683, 656, 630, 615, 552, 529.
Experimental details
Carbon-bound H atoms were placed in calculated positions and were included in the refinement in the riding model approximation, with Uiso(H) set to 1.2 Ueq(C). The oxygen-bound and nitrogen-bond H atoms were located on a difference Fourier map. The C17, C18 and C19 atoms were disordered.
Comment
In recent 20 years, a series of daidzein derivatives have been synthesized through different procedures to improve the adsorption and bioavailability of daidzein. Some daidzein derivatives were prepared by nitration substitution reaction, Mannich reaction, sulfonation reaction, phosphorylation reaction and glycosylation reaction [5], [6], [7], [8]. In this study, we synthesized a new daidzein derivative with three different groups. The title compound was obtained from sodium 2-hydroxy-5-(7-hydroxy-4-oxo-4H-chromen-3-yl)benzenesulfonate via Mannich reaction and nitration substitution reaction. Studies of the pharmacological activities of the title compound are in progress. The title compound contains one zwitterion and one water molecule in the asymmetric unit (cf. the figure). The dihedral angle between planar rings B (C10–C15) and C (C7–C9/O3/C5/C4) is 38.62°. The nitrogen atom N2 is protonated. The molecule shows an intramolecular O4–H4⋅⋅⋅O8 hydrogen bond of length 1.900 Å. There exist various O–H⋅⋅⋅O and N–H⋅⋅⋅O hydrogen bonds. Together with hydrogen bonds interactions a three-dimensional network is obtained.
