selective product formation and high yields are the advantages of this method. The synthesis of a series of novel quinoline fused imidazo[4,5-c]quinolines was accomplished by a simple, efficient, iodine–dimethyl sulfoxide (I2–DMSO) promoted sequential oxidative cross coupling followed by intramolecular cyclization of pyridoimidazole arylamines and carbonyl compounds in a one-pot reaction. Simple reaction
摘要 一系列新颖的喹啉稠合的咪唑并[4,5- c ]喹啉的合成是通过简单,有效的碘-二甲基亚砜(I 2 -DMSO)促进的顺序氧化交叉偶联,然后进行吡啶并咪唑芳胺和羰基的分子内环化一锅反应中的化合物。简单的反应条件,无金属催化剂,无添加剂,无配体,选择性的产物形成和高收率是该方法的优点。 一系列新颖的喹啉稠合的咪唑并[4,5- c ]喹啉的合成是通过简单,有效的碘-二甲基亚砜(I 2 -DMSO)促进的顺序氧化交叉偶联,然后进行吡啶并咪唑芳胺和羰基的分子内环化一锅反应中的化合物。简单的反应条件,无金属催化剂,无添加剂,无配体,选择性的产物形成和高收率是该方法的优点。
