Abkoemmlinge der 3-Chinolincarbonsaeure mit Sauerstoffsubstitution in Stellung 4,5 und 8: Synthese, Reaktionen, NMR-Studien

Starting from either 1,4-dibenzyloxybenzene (7) or 2,5-dimethoxyaniline (16), synthetic routes have been developed to benzenoid and quinoid derivatives of 4-oxo-1,4-dihydro-3-quinolinecarboxylic acid with O-bearing substituents in the positions 5 and 8 (c
