cis-and trans-2-Methoxymethylene-3-ethoxypropiontirile and 2-ethoxymethylene compounds are successfully separated and their structures were determined. Corresponding ester derivatives were not able to separate, however, the ratio of cis/transformation was made clear by elimination of ethyl alcohol from corresponding acetal compounds.
