Ethyl 2-formamido-2-(4-iodobenzyl)-3-(4-iodophenyl)propionate and ethyl 2-(3-bromobenzyl)-3-(3-bromophenyl)-2-formamidopropionate.
The title compounds, C(19)H(19)I(2)NO(3) and C(19)H(19)Br(2)NO(3), are derivatives of alpha-aminoisobutyric acid with halogen substituents at the para and meta positions, respectively. The ethoxycarbonyl and formamide side chains attached to the C(alpha) atom of the molecule adopt extended and folded conformations, respectively. The crystal structures are stabilized by N-H.O, C-H.O, C-Br.O and C-I.O interactions.
