efficient dimedone‐catalyzed synthesis of highly functionalized thiazol‐2‐yl substituted E‐acrylonitrile derivatives has been established through two‐step reaction of α‐thiocyanate ketones with malononitrile and amines. The α‐thiocyanate ketones were subjected with malononitrile to provide thiazol‐2‐ylidenemalononitrile derivatives, followed with various amines in the present of dimedone to yield the
通过α-硫氰酸酯酮与丙二腈和胺的两步反应,已经建立了高效的由二甲酮催化的高官能度噻唑-2-基取代的E-丙烯腈衍生物的合成方法。将α-硫氰酸酯酮与丙二腈进行合成,以提供噻唑-2-亚甲基丙二腈衍生物,然后在二甲基酮的存在下提供各种胺,以生成最终的由噻唑-2-基取代的丙烯腈衍生物。
