Pd-Catalyzed Benzylic C–H Amidation with Benzyl Alcohols in Water: A Strategy To Construct Quinazolinones

摘要

A novel method for the synthesis of 4-phenylquinazolinones via a palladium-catalyzed domino reaction of o-aminobenzamides with benzyl alcohols is developed. This protocol involves N-benzylation, benzylic C–H amidation, and dehydrogenation in water, which may play an important role in the smooth generation of the (η3-benzyl)palladium species by activation of the hydroxyl group of the benzyl alcohol.
