摘要
An efficient palladium-catalyzed difunctionalization/dearomatization of N-benzylacrylamides with alpha-carbonyl alkyl bromides as alkyl radical precursors has been described. Various alpha-carbonyl alkyl bromides, including alpha-bromoalkyl esters and ketones, reacted smoothly to provide important azaspirocyclohexadienones in moderate to excellent yields. In addition, mechanistic studies suggested that the reaction proceeded via a radical pathway.
