A synthetic strategy based on the sequential application of an aromatic aza-Claisen rearrangement and an intramolecular Heck reaction sequence as the key steps has been developed for the synthesis of various hitherto unreported coumarin- and quinolone-annulated benzazocine derivatives in excellent yields. aza-Claisen rearrangement - Heck reaction - benzazocine - coumarin - quinolone - palladium catalyst
