    The electrochemical thiocyanation of barbituric acids with NH4SCN was disclosed in an undivided cell under constant current conditions. The electrosynthesis is the most efficient at a record high current density (janode ≈50–70 mA cm−2). NH4SCN has a dual role as the source of the SCN group and as the electrolyte. Electrochemical thiocyanation of barbituric acids starts with the generation of (SCN)2
    巴比妥酸与 NH 4 SCN 的电化学硫氰化反应在恒流条件下的未分隔电池中进行了公开。在创纪录的高电流密度( j阳极≈50–70 mA cm -2)下,电合成效率最高。NH 4 SCN 作为SCN基团的来源和作为电解质具有双重作用。巴比妥酸的电化学硫氰化反应始于 (SCN) 2的生成来自硫氰酸根阴离子。将硫氰加成到巴比妥酸的烯醇互变异构体的双键上,得到硫氰化巴比妥酸。各种具有不同官能团的硫氰化巴比妥酸以 18-95% 的收率获得,并显示出有希望的抗真菌活性。

    The generation of peroxy radicals from hydroperoxides with subsequent selective peroxidation of 1,3-dicarbonyls in an undivided electrochemical cell under constant current conditions is reported. The method provides a variety of peroxy-containing barbituric acids and 4-hydroxy-2(5H)-furanones with yields of up to 74%. Only the combination of anodic and cathodic processes provides efficient peroxidation

    The three-dimensional structure of 1,3-dirnethyl-5-(4-allyloxybenzyl)-5-cytisylmethylbarbituric acid was found by x-ray structure analysis. A conformation with proximal cytisine and 2,4,6-trioxopyrimidine moieties was observed. Analogous structures for other synthesized 1,3-dimethyl-5-arylmethyl-5-cytisylmethylbarbituric acids and their 2-thio analogs were proved and the intramolecular effects caused by mutual magnetic shielding of spatially proximal groups were studied using PMR.
  • Chemical modification of plant alkaloids. I. Aminomethylation of barbituric acid derivatives by cytisine
    作者:K. A. Krasnov、V. G. Kartsev、A. S. Gorovoi
    DOI:10.1007/bf02236429
    日期:2000.3
    Reaction of cytisine with 1-mono- and 1,3-disubstituted 5-arylmethylbarbituric acids in the presence of formaldehyde results in aminomethylation of C-5 to form the corresponding 5-cytisylmethylbarbituric acids. The structures of the products are found using PMR spectroscopy mid mass spectrometry. 1-Phenyl-5-(2,4-dimethoxybenzyl)-5-cytisylmethylbarbituric acid is obtained as a mixture of two steroisomers in an approximately 2:1 ratio.
