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.
反式和顺式-2-甲氧亚甲基-3-乙氧基丙腈和2-乙氧亚甲基化合物被成功分离,并确定了它们的结构。然而,相应的酯衍生物未能分开,但通过从相应的缩醛化合物中除去乙醇,明确了顺反异构体比例。
