Abstract Some new (Z)-ethyl 3-amino-3-aryl-2-cyanopropenoates have been prepared in good yields by reacting (E)- and (Z)-ethyl 3-aryl-3-chloro-2-cyanopropenoates with primary and secondary amines. The (Z)-isomers were exclusively formed.although the starting material consisted of a mixture of (E)- and (Z)-isomers (≈ 1:1)
摘要 通过 (E)- 和 (Z)-3-芳基-3-氯-2-氰基丙烯酸乙酯与伯醇反应制备了一些新的 (Z)-乙基 3-氨基-3-芳基-2-氰基丙烯酸酯,收率良好。和仲胺。仅形成 (Z)-异构体。 尽管起始材料由 (E)- 和 (Z)- 异构体的混合物组成 (≈ 1:1)
