Hydroacridines: part 30. 1H and 13C NMR spectra of 9-substituted 1,2,3,4,5,6,7,8-octahydroacridines and of their N-oxides.
The 1H and 13C NMR chemical shifts of 1,2,3,4,5,6,7,8-octahydroacridine, 12 of its 9-substituted derivatives, and of the corresponding N-oxides were determined, assigned, and discussed in terms of 9-substituent effects and effects of N-oxidation. A good linear correlation was found between the 13C chemical shifts of the aromatic carbons in octahydroacridines and those of respective carbons in the corresponding N-oxides.
