The conformation of (R,S)-propiram and 8 analogues are investigated spectroscopically. Active analgesics are only found among the E-forms of the amides, in which the CH2 group of the propionyl substituent hangs over the pyridine ring - which itself stands vertical with respect to the planar amide group. The R-enantiomer of propiram is morphine-agonistic and corresponds to N-methylmorphinan in its spatial arrangement.
