This transformation could be used for the synthesis of biologically important 3-hydroxy-2-oxindole derivatives in good to excellent yields and the catalyst could be reused for six times without significant decrease in activity.展开更多

The reactions proceeded smoothly under aqueous conditions at room temperature and generated the corresponding products in good to excellent yields. It is worth noting that alkyl amines which did not react in known approaches are well tolerated in our system.展开更多
