1-aminoisoquinoline derivatives by gold(III)-mediated domino reactions is described. This synthetic protocol starts from readily available 2-alkynylbenzamides and ammonium acetate and takes place under mild reaction conditions compatible with a variety of functional groups. A plausible mechanism for the domino process is proposed, supported by the reaction of a possible intermediate, N-(3-phenyl-1H-isochrom
描述了一种通过金(III)介导的多米诺反应向药学上感兴趣的1-氨基异喹啉衍生物的简便合成路线。该合成方案从容易获得的2-炔基苯甲酰胺和乙酸铵开始,并且在与各种官能团相容的温和反应条件下进行。提出了一种可行的多米诺骨牌机制,并由一种可能的中间体N-(3-苯基-1H-异色烯-1-亚烷基)丙-1-胺的反应所支持。
