A new strategy is developed for the synthesis of 1-aminoisoquinoline derivatives. This Rh(III)-catalyzed [4 + 2] annulation reaction employs benzamidines as efficient directing groups and the vinylene carbonate as an acetylene surrogate. Additionally, the reaction features broad substrate scopes and good yields, only producing carbonate anion as byproduct.
开发了一种用于合成 1-氨基异喹啉衍生物的新策略。这种 Rh(III) 催化的 [4 + 2] 环化反应使用苯甲脒作为有效的导向基团,使用碳酸亚乙烯酯作为乙炔替代物。此外,该反应底物范围广,收率好,只产生碳酸根阴离子作为副产物。
