  An NMR Study of Halogenated 1,4-Dihydro-1-ethyl-4-oxoquinoline-3-carboxylates

  摘要：

  Ethyl 1,4-dihydro-1-ethyl-4-oxoquinoline-3-carboxylate and 29 of its mono-, di- and tri-fluoro and/or -chloro derivatives were synthesized and their H-1, C-13 and F-19 NMR spectra were recorded. H-1,C-13 and F-19 chemical shifts, J(HH), J(FH), J(CF) and J(FF) coupling constants are reported. The C-13 substituent chemical shift values of the chloro and fluoro substituents were calculated by linear multiple regression.
