Abstract The crystal and molecular structure of the methyl ester of (Z)-N-acetyl-β(3′-pyridyl)-dehydroalanine [methylZ-2-acetamido-3(3′-pyridyl) propenoate] have been determined from three-dimensional X-ray data. Crystals are monoclinic, space groupP21]. The molecular [φ=−51.5(5),ψ=157.0(4)°] conformation is discussed making reference to previous experimental results of analogous amino acid derivatives (in particular, ethyl (Z)-N-acetyldehydrophenylalaninate) and theoretical predictions. On the basis of He(I) and He(II) photoelectron spectra, a similar conformation is proposed for the title molecule in the vapor phase also.
