zed domino reaction was developed to yield functionalized naphthalenes, quinolines, and isoquinolines. The reactions of various substituted 1-phenylprop-2-yn-1-ols containing electron-donating (EDG) and electron-withdrawing (EWG) groups and 1-heteroarylprop-2-yn-1-ols worked well with this procedure. Both electron-rich and -deficient aryl halides were satisfactory substrates for this reaction. This
开发了一种有效的钯/铜催化的多米诺反应,以产生功能化的萘、喹啉和异喹啉。含有给电子 (EDG) 和吸电子 (EWG) 基团的各种取代的 1-苯基丙-2-yn-1-醇与 1-杂芳基丙-2-yn-1-醇的反应适用于该程序。富电子和缺电子的芳基卤化物都是该反应的令人满意的底物。这种多米诺苯环化过程涉及 Sonogashira 交叉偶联反应,然后异构化为查耳酮,最后是分子内缩合反应。
