RING LITHIATION OF PYRIDONES
Meghani, Premji,Joule, John A.
, p. 1 - 8 (2007/10/02)
Lithiation of 1-methyl-2-pyridone takes place mainly at the methyl group which then leads to a dimer (11) by addition to a second mol equivalent of pyridone at C-6.Lithiation of 1-methyl-4-pyridone takes place cleanly and efficiently at C-2; this lithio d
