The synthesis of a series of ring-methylated 1-alkyl-1,4-dihydronicotinamides and the corresponding pyridinium salts is described.Their NMR properties involving aromatic-ring-shielding anisotropy, due to ring current effects, are discussed and compared with electron populations calculated from STO-3G results.
