We discovered that a reagent comprising a combination of PhBCl2 and nitriles was useful for syntheses of both 3-acylindoles and 1-(1H-indol-3-yl)alkylamine from indoles. The reaction proceeded selectively at the 3-position of indoles providing 3-acylindoles in moderate to high yields on treatment with the above reagent. Furthermore, the reaction provided the corresponding amine products in moderate
我们发现包含PhBCl 2和腈的组合的试剂可用于从
吲哚合成3-酰基环
吲哚和1-(1H-
吲哚-3-基)烷基胺。在用上述试剂处理后,该反应在
吲哚的3-位选择性地进行,从而以中等至高产率提供3-酰基环
吲哚。此外,在中间体
亚胺被NaBH 3 CN还原后,该反应以中等至高产率提供了相应的胺产物。这些反应在温和的条件下进行,适用于在3-位官能化的
吲哚的形成。
