Synthesis of Coumarin- and Quinolone-Annulated Benzazocinone Frameworks by a Palladium-Catalyzed Intramolecular Heck Reaction

[摘要]：A synthetic strategy based on the sequential application of an aromatic aza-Claisen rearrangement and an intramolecular Heck reaction as the key steps has been developed for the synthesis of various new coumarin- and quinolone-annulated benzazocinone derivatives in 60-70% yields.
