The NMR spectra of 15 novel guinolines containing 11-34 carbon atoms and bearing substituents such as hydroxyl, sunfo, chloro, bromo, amino, azo and carboxymetoxy groups were recorded in DMSO at 298 - 300 K. For seven quinolines, the 13C-NMR signals were assigned on the basis of an analyzation of the cross peaks in the HSQC and HMBC spectra. For the others, the assignation of 13C-NMR signals was accomplished using chemical shifts of analogous compounds. The received data well agree with the predicted structure of the examined quinolines.
