Natural abundance "0 NMR spectra for 42 aliphatic and 13 cyclic enaminones with tertiary amino groups are reported. The "0 NMR chemical shifts of enaminones depend upon the type, number and position of the substituents. Substituents at C-1 cause shielding, and those at C-2 or C-3 cause deshielding.
