studied. Those substrates possesing an electron-withdrawing group in a 1,3 relationship with the coordinating (-CH2OMe) group underwent regioselective metalation by the action of n-BuLi/THF. Highly substituted phenols can thus be readly prepared.
已经研究了几种对羟基苄基甲基醚的直接金属化。那些具有与配位基团(-CH 2 OMe)成1,3关系的吸电子基团的底物在n-BuLi / THF的作用下进行了区域选择性金属化。因此可以容易地制备高度取代的酚。
