Stahl, J. Wang, L. Sarkar, J. It was observed that the steric effects of the substituents play a more important role in the electrophilic aromatic annulation step, which is the rate-determining step , compared to the initial nucleophilic addition of the aniline to the di ketone. The reaction offers high efficiency, mild reaction conditions, easy operation, and broad functional-group tolerance. Regioselectivity[ edit ] The formation of the quinoline product is influenced by the interaction of both steric and electronic effects.
