标题:使用羟基吡啶甲酰胺配体的铜催化芳基卤化物的羟基化
摘要:卤代芳烃的羟基化是有机合成化学中的一个基本转变.羟基吡啶甲酰胺配体能够实现杂芳基卤化物的有效铜催化羟基化,并具有广泛的官能团耐受性. Cu-Mpbs 系统最初设计用于 C-N 偶联,可实现铜催化芳基溴的羟基化.相关衍生物 Cu-Hmps 为芳基溴,芳基碘和活化芳基氯的羟基化提供了出色的反应性和纯度.邻位活化底物对铜催化的羟基化表现出极高的反应活性和选择性.更困难的芳基氯化物,需要更高活化温度(120oc)的底物,可以通过具有优异的内在配体稳定性的cu-Dmps系统进行羟基化.可以通过配体,溶剂和碱基的选择来调整反应条件以适应目标底物.采用 Koh,K 2 Co 3 或 K 3 Po 4 水溶液(溶于环丁砜或环丁砜)设计了安全可靠的加工条件和酒精混合物.
