We have developed a new three-component approach using ortho-alkynylbenzaldoximes involving the formation of a cyclic nitrone in the presence of Br2 or ICl for the synthesis of 1-aminoisoquinolines via cascade 6-endo-cyclization, 1,3-dipolar cycloaddition reaction with 2H-azirines, and ring-opening reaction sequences. The broad range of structurally diverse products, good to high yields, high atom-economy
我们开发了一种新的三组分方法,使用邻-炔基
苯甲醛肟,包括在 Br 2或 ICl存在下形成环状硝酮,用于通过级联 6-内环化、1,3-偶极环加成反应合成
1-氨基异喹啉与 2 H-
氮丙啶和开环反应序列。结构多样的产品范围广、产率好到高、原子经济性高和成键效率高,使该方法成为合成
1-氨基异喹啉的有吸引力的替代方法。
