Directed lithiation of 1-dimethylamino- and 1-methoxynaphthalene, followed by Li-Mn exchange and reaction with electrophiles, provides regioselective syntheses of previously unknown racemic thioamides 2, 11 and 12, and ketones 5-8.

Lithiation of 1-substituted naphthalenes, followed by Li-Mn exchange, served for synthesis of title compounds.
