Isochromanone is the core structure of many bioactive compounds. Direct oxidation of isochromans is one of leading methods for the construction of isochromanones, while most established processes remain suffering from the use of environmentally unfriendly metal oxidants, harsh reaction conditions, and the difficulty in catalyst recycling and product separation. Herein, we report a convenient, cost-effective
异色满酮是许多生物活性化合物的核心结构。异色满的直接氧化是构建异色满酮的主要方法之一,但大多数已建立的工艺仍然存在使用环境不友好的金属氧化剂、苛刻的反应条件以及催化剂回收和产物分离的困难。在此,我们报道了一种方便、经济、绿色的方法,通过新型非均相钒簇催化剂(Cat.1 )在温和条件下通过O 2氧化异色满酮来合成高附加值异色满酮。该反应方案表现出高催化活性以及良好的催化剂可回收性和对多种底物的可重复使用性。
