especially for the synthesis of complex molecules. Herein, we report a mild, general, and functional group tolerant intramolecular hydroamination of unactivated olefins using a Co(salen) complex, an N-fluoropyridinium salt, and a disiloxane reagent. This method, which was carried out at room temperature (or 0 °C), afforded three-, five-, six-, and seven-membered ring nitrogen-containing heterocyclic compounds
官能团耐受性是化学反应的重要要求之一,特别是对于复杂分子的合成。在此,我们报告了使用 Co(salen) 配合物、N-氟吡啶盐和二硅氧烷试剂对未活化烯烃进行温和、通用和官能团耐受的分子内加氢胺化。该方法在室温(或 0°C)下进行,可得到三元、五元、六元和七元环含氮杂环化合物,并且与多种官能团相容。
