Ethyl (Z)-3-bromo-2-[(tert-butoxycarbonyl)amino]-3-phenylacrylate

P. G. Jones and S. Jäger

Abstract: The title compound, C₁₆H₂₀BrNO₄, displays almost planar coordination at the enamine N atom, which thus has a stereochemically inactive lone pair. There is no indication of delocalized charge within the didehydrogenated amino acid, as shown by the bond lengths. The molecules are linked in pairs by two hydrogen bonds (N-HO and C-HO), and then by a longer C-HO contact to form columns parallel to the a axis.
