Lithiation of 1-methyl-4-quinolone and 1-methylquinoline-4-thione with lithium diisopropylamide (LDA) at -78 deg C takes place at C-2.The resulting lithio-species react with a variety of electrophiles to give 2-substituted-4-quinolones and -quinolines-4-thiones respectively. 1-Methylquinoline-4-thione is easily converted into 1-methyl-4-quinolone in protic solution.
