• Discrepancies in the reactivity pattern of azaenamines towards cinnamonitriles: synthesis of novel aza-steroid analogues
  作者：Said A.S. Ghozlan、Amr M. Abdelmoniem、Holger Butenschön、Ismail A. Abdelhamid

  DOI：10.1016/j.tet.2015.01.026

  日期：2015.3

  Azaenamine incorporating pyrazole-4-carboxylate is prepared and allowed to react with alpha,beta-substituted nitriles. A new reactivity pattern was observed leading to the formation of substituted pyrazolo[4',3'-5,61 pyrimido[2,1-a]phthalazine-9-carbonitriles, which can be considered as aromatic aza-steroid analogues.
