  摘要：

  AbstractNew activated indolylpyrrolidones—their methylthiopyrrolinium salts—in the reactions with several CH‐acids were studied. 2‐Nitromethylene‐ and 2‐dicyanomethyleneindolylpyrrolidines were obtained from 5‐indolyl‐2‐methylthiopyrrolinium salts with good yields. The reduction in these nitro compounds yields the respective aminomethylpyrolidines. The rigid structure of the starting compounds has significant stereoelectronic requirements of nucleophilic agents.

  摘要：

  The reaction under mild conditions of 1-alkyl-5-hydroxypyrrolidin-2-ones with different indoles having a free 3 position leads exclusively to 1-alkyl-5-(indol-3-yl)pyrrolidin-2-ones but if position 3 is occupied to 1-alkyl-5-(indol-2-yl)pyrrolidin-2-ones.

  The mass spectrometric behavior of 1-alkyl-5-(1H-indol-2-yl)pyrrolidin-2-ones and 1-alkyl-5-(1H-indol-3-yl)pyrrolidin-2-ones was studied and the fragmentation of these compounds was established. The product of N-methylindole reaction with 1-benzyl-5-hydroxypyrrolidin-2-one was shown to be 1-benzyl-5-(1-methylindol-3-yl)pyrrolidin-2-one.
