An efficient synthesis of functionalized phenanthrenes has been developed for the first time involving an iron(III)-catalyzed intramolecular coupling of 2′-alkynyl-biphenyl-2-carbaldehydes. A broad range of functionalized phenanthrene derivatives could be obtained in the present method in moderate to good yields with high chemo- and regioselectivity. This transformation can also be applied to the synthesis
首次开发了一种有效的合成功能化菲的方法,该方法涉及铁(III)催化的2'-炔基-联苯-2-甲醛的分子内偶联。在本方法中,可以以中等到良好的产率以高的化学和区域选择性获得各种各样的官能化的菲衍生物。该转变也可以应用于有角度稠合的四环化合物的合成。该方法具有许多优点,例如高选择性,温和的反应条件和容易获得的起始原料。
