title: 1H and 13C NMR spectral assignments of pyridinium salts linked to a N-9 or N-3 adenine moiety.
abstract: (1)H and (13)C NMR spectral data of 13 new compounds containing a 4-(dimethylamino)- or 4-(pyrrolidin-1-yl)pyridinium moiety linked to the N-9 or N-3 nitrogen atom of an adenine moiety were assigned. 1D and 2D NMR experiments (DEPT, HSQC and HMBC) allowed the unequivocal identification of N-9 and N-3 isomers.
