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. coumarin - quinolone - benzazoninones - aza-Claisen rearrangement - Heck reaction
已经开发了一种基于芳香族氮杂-克莱森重排然后分子内Heck反应序列为关键步骤的合成策略,用于迄今未报道的香豆素和喹诺酮修饰的苯扎宗酮酮衍生物的区域控制合成,收率为48-69%。 香豆素-喹诺酮-苯并zon酮-氮杂-克莱森重排-Heck反应
