  Synthesis of 3-Methylthio-4-aryl-3-pyrroline-2,5-diones and 3-Arylpyrrolidine-2,5-diones by Reaction of Nitroketene Dithioacetal with Arylacetonitriles

  摘要：

  The reaction of nitroketene dithioacetal (1a), i.e., 2,2-bis(methylthio)-1-nitroethylene, with arylacetonitriles (2a-I) in the presence of the base like sodium hydroxide gave 4-nitrobut-2-enenitriles (3a-I) which were converted into 5-hydroxyimino-4-methylthio-3-phenyl-3-pyrrolin-2-ones (4a-i) under refluxing in methanol. Title compounds (5a-i) were readily obtained by the treatment of 4a-i with hydrochloric acid and were finally led to N-methylated products (6a-I) with methyl iodide. The reduction of maleimides (4-6) with zinc dust in acetic acid afforded the corresponding 3-arylpyrrolidine-2,5-diones (7a-i) that can be converted to pharmacologycally active compounds like mesembrines.

  converted to DMS in situ, which subsequently served as a methylthiolation reagent in the reaction. To the best of our knowledge, this protocol provided the first known example of convergent integration of three self-sorting domino sequences.

  描述了由I 2促进的三组分偶联反应，用于由甲基酮与乙腈和DMSO构建3-（甲硫基）-4-芳基-1 H-吡咯-2,5-二酮。该转化涉及α-酮酰亚胺的原位产生和应用。此外，DMSO原位转化为DMS，随后在反应中用作甲基硫醇化试剂。据我们所知，该协议提供了三个自排序多米诺骨牌序列的融合整合的第一个已知示例。
