  • Application of a Highly Robust and Efficient Fluorescence-Resonance-Energy-Transfer (FRET) System in DNA

    feasibility study for the application of our newly developed highly efficient and robust fluorescence-resonance-energy-transfer (FRET) system to DNA. A 2′-oligodeoxynucleotide, 12, equipped with a quinolinone derivative as donor and a (bathophenanthroline)ruthenium(II) complex as acceptor and having a single uridine as potential cleavage site under basic conditions revealed an intensive FRET, which almost vanished

  • Long-Wavelength-Absorbing and -Emitting Carbostyrils with High Fluorescence Quantum Yields
    作者:Georg Uray、Karlheinz S. Niederreiter、Ferdinand Belaj、Walter M. F. Fabian
    DOI:10.1002/(sici)1522-2675(19990908)82:9<1408::aid-hlca1408>3.0.co;2-q
    日期:1999.9.8
    Synthesis, absorption and fluorescence spectra, as well as quantum yields of a series of donor-acceptor-substituted carbostyrils (= quinolin-2(1H)-ones), are reported. Unprecedented strong absorption maxima (epsilon = 10000-20000) close to the visible spectrum, large Stokes shifts up to 130 nm, and quantum yields up to 0.7 are obtained with derivatives containing donor substituents at C(6) and C(7), and either one Ph substituent at C(3) or one CF3 residue at C(4). For analytical applications in biochemistry and medicine, N(1)-functionalization, or amidoacylation at C(3) in the case of the CF3 derivatives, is possible without a concomitant hypsochromic shift of their absorption and emission maxima. Semiempirical molecular-orbital calculations (AM1 for structures, ZINDO for electronic transition energies) prove to bit a suitable tool for the prediction of absorption properties of these compounds. The crystal-structure analysis of 6,7-dimethoxy-1-methyl-3-nitro-4-(trifluoromethyl)quinolin-2-(1H)-one (7) (C13H11F3N2O5, monoclinic, P2(1)/c, a = 12.372(2), b = 12.154(2), c = 10.119(2)Angstrom, beta = 112.95(2)degrees) shows that the NO2 group, squeezed between the CF3 and the C=O group, is oriented almost perpendicularly (87.8(4)degrees) to the ring plane. The intramolecular F ... N distance between the CF3 and the NO2 group is only 2.513(4)Angstrom.
  • Intramolecular amidation — An efficient synthesis of 3-aryl-2-quinolinones

    DOI:10.1139/v06-163
    日期:2006.12.1

    To reveal the scope of the syntheses of 3-aryl-2-quinolinones from 2-nitro-α-phenylcinnamic acids, the isomerization of (E)-2-amino-α-phenylcinnamic acids was studied. The results showed that (E)-2-amino-α-phenylcinnamic acids were isomerized to its (Z)-forms under sunlight in organic solvents. The reaction temperature and the functional groups at both phenyl rings have no effect on the isomerization of (E)-2-amino-α-phenylcinnamic acids and the following intramolecular spontaneous amidation of (Z)-2-amino-α-phenylcinnamic acids. Various 3-aryl-2-quinolinones prepared in high total yields indicated that the syntheses of 3-aryl-2-quinolinones from Perkin condensation products 2-nitro-α-phenylcinnamic acids via reduction, sunlight-induced isomerization of (E)-2-amino-α-phenylcinnamic acids, and the following intramolecular amidation is an efficient procedure. Key words: 3-aryl-2-quinolinones, isomerization, amidation.
