The powerful ortho-metalating directive effect of the N, N-dialkylcarboxamide group can be used for the preparation of C-1 alkyl-substituted 2, 6-acylnaphthols. The alternative reaction pathways of C-1 metalation vs. acylation (carbonyl addition) in the reaction of alkyllithium reagents with Nfl-dialkyl-6-methoxynaphthalenecarboxamides depends upon the cumulative steric nature of the N-alkyl and lithium alkyl groups: The NJV-dimethylamide 7 ...
