Directed lithiation of unprotected pyridinecarboxylic acids
Mongin, Florence,Trecourt, Francois,Queguiner, Guy
, p. 5483 - 5486 (1999)
The lithium 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 chlor
