Notes:
The complete assignment of the 13C NMR spectra of a series of biologically active quipazines substituted at position C-5, C-6 or C-7 of the quinoline moiety provides evidence for a strong conjugation between the π-electron cloud of the pyridine ring and the nitrogen lone pair of the piperazinyl residue. The SCS values of these quipazines are compared with those of the analogous quinolines, and their deviations are discussed in terms of conjugation effects.
