An efficient copper-catalyzed solvent-switchable regioselective 1,2- or 1,6-addition of quinones with boronic acids has been developed. This novel catalytic protocol for the synthesis of various quinols and 4-phenoxyphenols was enabled by a simple solvent swap between H2O and MeOH. It features mild reaction conditions, simple and easy operation, broad substrate scope and excellent regioselectivity
已经开发出一种有效的铜催化溶剂可转换的醌与硼酸的区域选择性 1,2-或 1,6-加成反应。这种用于合成各种对苯二酚和 4-苯氧基苯酚的新颖催化方案是通过 H 2 O 和 MeOH 之间的简单溶剂交换实现的。其具有反应条件温和、操作简单易行、底物范围广、区域选择性优良等特点。还成功地研究了克级反应以及两种加成产物的进一步转化。
