  Approaches to the Construction of Substituted 4-Amino-1H-pyrrol-2(5H)-ones

  摘要：

  Fully substituted 4-aminopyrrolones are easily accessed via simple routes starting from imines, ketones, or alpha-bromophenyl acetonitriles. Imines were reacted with KCN/NH4Cl in aqueous ethanol to produce alpha-arylamino benzyl cyanides. On the other hand, ketones were transformed to the desired alpha-amino nitriles using a modified Strecker reaction. Then, alpha-amino nitrile precursors were allowed to react with a suitable acyl halide to produce the corresponding amides. Further treatment of these amides with ethanolic KOH converted them to highly substituted 4-amino-1H-pyrrol-2(5H)-one derivatives in moderate to excellent yields.
