Abstract
The crystal and molecular structure of the β,β′-disubstituted dehydroamino acid derivative acetylaminoethenetricarboxylic acid trimethyl ester has been determined from three-dimensional X-ray data. C10H13NO7 is monoclinic, space group P21/c, with Z = 4 in a cell of dimensions a = 8.963(2), b = 17.027(3), c = 8.248(2) Å, β = 99.79(5). The conformation [φ = 3.6(4), ψ = 74.1(3)°] is different from that of any dehydroamino acid derivative reported so far and it is discussed on the basis of previous theoretical predictions and experimental results of analogous molecular systems.
