salts of 2-, 3- and 4-pyridinecarboxylic acids undergo deprotonation at the position adjacent to the carboxylate group when treated with LTMP in THF at 0 °C, −50 °C and −25 °C, respectively. The lithiation conditions could be extended to chloronicotinic acids, and even to an activated benzoic acid.
当分别在0°C,-50°C和-25°C下用LTMP在THF中处理时,2-,3-和4-吡啶羧酸的锂盐会在与羧酸酯基团相邻的位置发生去质子化。锂化条件可以扩展到氯烟酸,甚至扩展到活化的苯甲酸。
