1 Source of materials
To a stirred solution of 3-dimethylamino-2-(2,3,4,5-tetrafluoro-benzoyl)-acrylic acid ethyl ester (31.9 g, 0.1 mol) in CH2Cl2 (150 mL) was added α-furan-2-yl-methylamine (1.0 g, 0.1 mol), and then the reaction mixture was refluxed for about 0.5 h. After the reaction completed (monitored by TLC), the CH2Cl2 was distillated under reduced pressure to give crude product. The crude product was poured into water (40 mL) and extracted with EtOAc (50 mL × 3). The EtOAc solvent was evaporated to provide 3-[(furan-2-ylmethyl)-amino]-2-(2,3,4,5-tetrafluoro-benzoyl)-acrylic acid ethyl ester being suitable for X-ray analysis in 85.0 % yield. 1H (400 MHz) and 13C (100 MHz) NMR spectra of 3-[(furan-2-ylmethyl)-amino]-2-(2,3,4,5-tetrafluoro-benzoyl)-acrylic acid ethyl ester were recorded on a Bruker Avance 400 spectrometer in CDCl3 using tetramethylsilane (TMS) and CDCl3 (13C, δ 77.0 ppm) as internal standards. J-values were given in Hertz. 1H NMR (400 MHz, CDCl3): δ = 1.09–1.13 (t, J = 8.0, 3H, OCH2CH3), 4.05–4.10 (q, J = 8.0, 12.0 Hz, 2H, OCH2CH3), 4.57–4.59 (d, J = 8.0 Hz, 2H, NHCH2), 6.34–6.39 (m, 2H, Furanyl-H), 6.95–7.01 (m, 1H, Ph–H), 7.45–7.47 (d, J = 8.0 Hz, 1H, OCH=C), 8.18–8.21 (d, J = 12.0 Hz, 1H, C=CHNH), 10.98 (br, 1H, NH) ppm. 13C NMR (100 MHz, CDCl3): δ = 187.14, 166.25, 160.56, 160.11, 148.29, 143.69, 143.58, 143.50, 110.72, 109.98, 109.79, 109.29, 109.09, 101.62, 60.06, 46.50, 14.00 ppm.
2 Experimental details
All H atoms were included in calculated positions and refined as riding atoms, with C–H = 0.90–0.97 Å with Uiso(H) = 1.5 Ueq(C) for methyl H atoms and 1.2 Ueq(C) for all other H atoms.
3 Comment
Quinolones have been popularized rapidly in clinic and become significant drug in the development, production and application all over the world due to wider antibacterial spectrum and stronger antibacterial activity than common antibiotics [5, 6]. After being used or even abused for a long time, quinolones have been seriously resisted by bacteria because of gene mutations and also have the inevitable side effects [7], [8], [9]. Nowadays, a new effective fluoroquinolones against bacteria drug-resistant and side effects have been researched and developed [10–13]. Recently, an impactful and high-yielding method for the synthesis of fluoroquinolones is developed in our group, and single crystals of several key intermediates are achieved.
In the molecule of the title compound bond lengths and angles within 3-[(furan-2-ylmethyl)-amino]-2-(2,3,4,5-tetrafluoro-benzoyl)-acrylic acid ethyl ester are very similar to those given in the literature [11, 12]. The dihedral angles between the C1–C6 benzene ring, O2–C9–O3 carboxyl group and the furan ring are
