摘要
A synthetic strategy based on the application of the aromatic aza-Claisen rearrangement followed by an intramolecular Heck reaction sequence as the key step has been developed for the regiocontrolled synthesis of hitherto unreported coumarin- and quinolone-annulated benzazoninone derivatives in 48-69% yield.
