  us to obtain 2-pyrrolidones with oxo and cyano groups in the substituent at the nitrogen atom, because the reduction amination process was accompanied by hydrogenation of these functional groups. Introduction of an oxoalkyl substituent at the nitrogen atom of pyrrolidin-2-ones offers the possibility to modify their structures by reactions involving the oxo group, which leads to the synthesis of new

  以前，我们开发了一种方法来获得在第二个氮原子的取代基中含有各种官能团的 2 吡咯烷酮。该过程本质上是通过除伯氨基之外还含有所需官能团的特殊试剂对 y-酮羧酸酯进行催化还原胺化。使用这种方法，我们已经合成了含有各种片段的 N 取代 2-吡咯烷酮，例如 (CH2)2OH、(CH2)2NHZ、CH2COOC2H 5、CH2COONH2 等 [1 4]。然而，这种方法不允许我们获得在氮原子取代基中具有氧代和氰基的 2-吡咯烷酮，因为还原胺化过程伴随着这些官能团的氢化。在 pyrrolidin-2-ones 的氮原子上引入氧代烷基取代基提供了通过涉及氧代基团的反应来修改其结构的可能性，这导致合成新的生物活性化合物。为了获得取代基中带有氰基和氧代基团的吡咯烷-2-酮，我们使用了未取代氮的 2-吡咯烷酮与 α,13-不饱和腈或酮之间的反应。早先 [5] 我们已经报道了 5-烷基-2-吡咯烷酮的氰乙基化反
