一般說明

1，3-二甲基巴比妥酸（1，3-二甲基-2，4，6（1H，3H，5H）-嘧啶三酮）是活性亚甲基化合物。它经历空心 Pd6 水溶性笼，与芘-1-甲醛，[{（tmen）Pd} 6（timb）4]（NO3）12（tmen =N,N,N′,N′-四甲基乙二胺，timb = 1，3，5-tris （1-咪唑基）苯）催化的诺文葛尔缩合反应。它经过自分选的 Pd7 分子舟实验，其与各种芳香醛，具有内部纳米腔（催化剂）辅助的诺文葛尔缩合反应。它通过 1，3-二甲基脲、丙二酸和乙酸酐在乙酸中反应合成。它广泛用于合成各种合成中间体和杂环化合物。

應用

1，3-二甲基巴比妥酸可用于以下研究：
  • 具有五个立体中心的异色烯嘧啶二酮衍生物的对映选择性合成，通过一锅式迈克尔-诺文葛尔缩合-反电子-需要杂-狄尔斯-阿尔德反应。
  • 5-芳基-6-（烷基 - 或芳基 - 氨基）-1，3-二甲基呋喃[2，3-d]嘧啶衍生物的合成。
  • 微波促进醇的间接官能化，通过使用顺序一锅式 Ir（III）/Pd（0） 催化过程的螺环化。

Electrochemical oxidation of trimipramine in the absence and presence of 1,3 dimethyl barbituric acid as a nucleophile in aqueous solution has been studied using cyclic voltammetry and controlled-potential coulometry electrolysis. Voltammetric studies of electro-oxidation of trimipramine were realized in a
