中文摘要: |
对具有高生物活性的4'-三氟甲基-3,2'-吡咯烷基双螺环氧化吲哚及其衍生物进行了探索合成。在有机小分子碱三乙胺催化作用下,由3-异硫氰基氧化吲哚与3-三氟亚乙基羟吲哚在二氯甲烷(DCM)溶剂中于室温下发生3+2环合加成反应,高产率(85%~96%)获得4'-三氟甲基-3,2'-吡咯烷基双螺环氧化吲哚。通过核磁共振氢谱和碳谱、高分辨质谱等手段对已合成的产物进行表征。这一合成方法具有简单,高效,环保的特点。 |
英文摘要: |
The synthesis of 4'-trifluoromethyl-substituted 3,3'-pyrrolidinyl-dispirooxindoles and its derivatives with high biological activity was explored. Under the catalysis of organic triethylamine, 3-isothiocyanato oxindoles reacted with 3-trifluoroethylidene oxindoles in dichloromethane (DCM) at room temperature, A 3+2 cyclization addition reaction was carried out to obtain a high yield (85%~96%) of 4'-trifluoromethyl-substituted 3,3'-pyrrolidinyl-dispirooxindoles. The synthesized products were characterized by 1H-NMR, 19F-NMR, 13C-NMR and high-resolution mass spectrometry. This synthetic method is simple, efficient and environmentally friendly. |
