  摘要：

  在基于邻-金属化位点在芳族化学的新值一般方法邻- ，间- ，和对-茴香酸（1 - 3）（方案1）进行说明。通过改变碱，金属化温度和曝光时间，可以将金属化选择性地定向到任何一个邻位。的金属化邻-茴香酸（1）与小号正丁基锂/ TMEDA在THF中在-78℃下在位置adjacente将羧酸只发生。另一方面，通过n -BuLi / t -BuOK观察到区域选择性的逆转。在LTMP为0°C的情况下，间苯二酸的两个指向矢（2）协同作用以直接将金属引入它们之间，而n - BuLi / t- BuOK优先除去位于甲氧基和羧酸酯（H-4）对位的质子。s- BuLi / TMEDA仅在羧酸酯附近与对茴香酸（3）反应。根据这些方法，已开发出通过多种途径难以达到的，具有多种功能的非常简单的甲氧基苯甲酸的途径（表1）。
